# Change compression method to 7z (2025-11-10 16:59Z)
_**User (2025-11-10 16:59Z)**_
@zip_sequences.py (1-334) let's have it use 7z at compression lvl 9 instead of zip at 0 (store) I don't mind it taking a few minutes per zip if they're more compressed.

Updated the script to use 7z with compression level 9 instead of Python's zipfile with no compression. Changes:
1. **Added subprocess import** for calling 7z
2. **Changed archive format** from `.zip` to `.7z`
3. **Replaced `zip_sequence` function** to use `7z a` with:
- `-mx=9`: maximum compression
- `-mmt=on`: multi-threading
- `-y`: assume yes to prompts
4. **Replaced `expand_sequence` function** to use `7z x` for extraction
5. **Updated all file pattern searches** from `*.zip` to `*.7z`
6. **Updated docstring** to reflect 7z usage
The script now creates 7z archives with maximum compression. Compression may take longer, but archives will be smaller. Ensure 7z is installed and available in your PATH (typically `7z.exe` on Windows).

Updated the cleanup function to automatically remove old `.zip` files. When you run the script, it will:
1. Remove obsolete `.zip` files (migrated to `.7z`)
2. Remove orphan `.7z` archives (when the sequence directory no longer exists)
3. Clean up associated `.meta.json` state files
No need to manually delete the `_zipped` folder. The next run will remove old `.zip` files and create new `.7z` archives with maximum compression. The cleanup runs automatically after the zip operation completes.

Updated the code to check `ZIPPER_TYPE` directly instead of `USE_7Z`. Changes:
1. **Removed the `USE_7Z` variable** — now checking `ZIPPER_TYPE == "7z"` directly
2. **Updated `zip_sequence` function** — checks `ZIPPER_TYPE == "7z"` and raises an error if 7z is requested but not found
3. **Updated `expand_sequence` function** — same logic, checks `ZIPPER_TYPE` directly
4. **Updated warning message** — warns if 7z is requested but not found, but doesn't silently fall back
The script now respects the config:
- If `"zipper": "7z"` → uses 7z compression (or errors if 7z not found)
- If `"zipper": "zip"` → uses Python's zipfile module
It will use the compression method specified in your config.

Fixed the issue. Windows has a command-line length limit (~8191 characters), and with 470+ files the command exceeded it.
The fix:
1. **Uses a temporary list file** - Creates a `.lst` file containing all file paths (one per line)
2. **Uses 7z's `@listfile` syntax** - Instead of passing all files as command arguments, 7z reads the list from the file
3. **Better error handling** - Captures and reports stderr from 7z
4. **Cleanup** - Removes the temporary list file after use
This avoids the command-line length limit and should work with any number of files. Try running the batch file again; it should work now.

Added the `Get-ProjectPathFromUser` function to `ConfigLoader.ps1`. It:
1. **Prompts the user** to paste the project path
2. **Validates the path** - checks if it exists and is a directory
3. **Handles quotes** - automatically removes surrounding quotes if pasted
4. **Provides retry logic** - asks to try again if the path is invalid
5. **Returns the resolved path** - returns the full normalized path if valid, or `$null` if the user cancels
You can use it in your scripts like this:
```powershell
. .\ConfigLoader.ps1
$projectPath = Get-ProjectPathFromUser
if ($null -ne $projectPath) {
Write-Host "Deploying to: $projectPath"
# Your deployment logic here
}
```
Or with a custom prompt:
```powershell
$projectPath = Get-ProjectPathFromUser -Prompt "Enter the target project directory:"
```
The function will keep prompting until a valid directory path is provided or the user chooses not to retry.

When you run `ConfigLoader.ps1` directly, it will:
1. **Prompt you** to paste the project path
2. **Validate the path** and ask to retry if invalid
3. **Display the resolved path** in green if successful
4. **Exit with an error** if you cancel
You can run it like:
```powershell
.\ConfigLoader.ps1
```
or
```powershell
& .\ConfigLoader.ps1
```
If you dot-source it (`. .\ConfigLoader.ps1`), it will only load the functions without prompting, so you can still use it as a library in other scripts.
The script detects whether it's being run directly or dot-sourced and behaves accordingly.

Fixed both issues:
1. **Double colon fixed** - Removed the colon from the prompt string since `Read-Host` adds one automatically
2. **Deployment added** - When run directly, it now automatically calls `UpdateProjectBatches.ps1` with the provided project path
When you run `.\ConfigLoader.ps1` now, it will:
1. Prompt for the project path (no double colon)
2. Validate the path
3. Automatically run `UpdateProjectBatches.ps1` to deploy batch files and config to that project
4. Show success/error messages
The script will deploy the helper batch files and config files to the project you specify.

Completed all tasks:
1. **Fixed Unicode characters** - Replaced checkmark (✓) and cross (✗) in `UpdateProjectBatches.ps1` with ASCII-safe `[OK]` and `[FAIL]`.
2. **Updated `Use-IsoDailyFormat`** - Handles both boolean (backward compatible) and string values. Returns `$true` for ISO format strings (containing "YYYY-MM-DD" or matching the date pattern), `$false` otherwise.
3. **Updated `Use-7Zip`** - Handles both boolean (backward compatible) and string values. Returns `$true` if the string equals "7z" (case-insensitive), `$false` otherwise.
All functions maintain backward compatibility with boolean values while supporting the new string-based config format. No linter errors. The integration issues should now be resolved.

**Analyzing PowerShell param block issue**
I'm focused on fixing the problem where the param block in UpdateProjectBatches.ps1 is not recognized because Set-StrictMode precedes it, which is invalid syntax. My plan is to reorder the script’s top lines by moving the param block above Set-StrictMode and possibly adding `[CmdletBinding()]` to properly define parameters. I'll verify the file’s current top lines, then perform a targeted search-and-replace to adjust the structure and address the error.Tool use: **read_file** • Read file: UpdateProjectBatches.ps1

Fixed the issue. When `Where-Object` returns a single item, PowerShell returns a single object, not an array, so `.Count` isn't available. Using `@($targets).Count` ensures it's treated as an array and works for both single items and collections.
The linter warning about `PSScriptRoot` is expected; it's a common pattern for compatibility with older PowerShell versions. The script should now work correctly.

Deployment completed successfully. All batch files were updated:
- **UpdateSequences.bat**: 5 files updated
- **UpdateAllSequences.bat**: 1 file updated
- **ZipSeqArchv.bat**: 1 file updated
- **UnzipSeqArchv.bat**: 1 file updated
- **NewDaily.bat**: 2 files updated
The integration is working:
1. Unicode characters fixed (using `[OK]` and `[FAIL]`)
2. ConfigLoader functions updated to handle string-based config
3. Script execution fixed (using `powershell -File`)
4. Array count issue fixed (using `@($targets).Count`)
The deployment workflow is functional. Running `ConfigLoader.ps1` prompts for a project path and automatically deploys the batch files and config to that project.

Made two changes:
1. **Fixed list file handling** - The list file is now explicitly closed before 7z reads it, and we use an absolute path. Previously, the file might not have been flushed when 7z tried to read it.
2. **Delete existing zip files** - Any existing zip file is deleted before creating a new one to avoid corruption issues that could cause the "Unexpected end of archive" error.
The changes ensure:
- The list file is fully written and closed before 7z accesses it
- The list file path is absolute (required by 7z's `@` syntax)
- No corrupted zip files interfere with the compression
Try running the script again; it should work now.

Made these changes:
1. **Added `time` import** at the top of the file
2. **Ensured file is fully written** - Added `flush()` and `fsync()` to ensure the list file is written to disk before 7z reads it
3. **Added retry logic** - If the file is still locked when we try to delete it, we retry up to 3 times with a 100ms delay between attempts
This should fix both issues:
- The file is fully written and synced to disk before 7z reads it
- If 7z still has the file open when we try to delete it, we retry with a delay
The script should now work correctly. Try running it again.

Create Simple Helper Script\nCreate `GetStructDir.ps1` in ProjectStructure that:\n- Reads `config.json` from project root `.config` folder\n- Returns the `structDir` value\n- No other dependencies or functions\n\n### 2. Update UpdateProjectBatches.ps1\n- Remove `ConfigLoader.ps1` from `$sharedAssets` (line 59)\n- Change config.json deployment target to `projectroot\\.config\\config.json`\n- Deploy `GetStructDir.ps1` to `projectroot\\.config\\GetStructDir.ps1`\n- Update deployment logic to create `.config` directory if needed\n\n### 3. Update All Batch Files\nUpdate these files to use new structure:\n- `ZipSeqArchv.bat`\n- `UnzipSeqArchv.bat`\n- `UpdateSequences.bat`\n- `UpdateAllSequences.bat`\n- Any other batch files that use ConfigLoader\n\nChanges for each:\n- Remove ConfigLoader.ps1 checks\n- Point to `%PROJ_ROOT%\\.config\\config.json`\n- Use `GetStructDir.ps1` or direct JSON parsing to get structDir\n- Update error messages\n\n### 4. Files to Modify\n- `GetStructDir.ps1` (new file)\n- `UpdateProjectBatches.ps1`\n- `ZipSeqArchv.bat`\n- `UnzipSeqArchv.bat`\n- `UpdateSequences.bat`\n- `UpdateAllSequences.bat`",

To-do's from the plan have already been created. Do not create them again. Mark them as in_progress as you work, starting with the first one. Don't stop until you have completed all the to-dos.

Merged UpdateProjectBatches.ps1 into ConfigLoader.ps1. When ConfigLoader.ps1 is run directly, it:
1. Prompts for the project path
2. Validates the project directory
3. Updates all batch files in the project (UpdateSequences.bat, ZipSeqArchv.bat, etc.)
4. Deploys config files to `projectroot\.config\`
5. Shows a summary of what was updated
All functionality from UpdateProjectBatches.ps1 is now integrated into ConfigLoader.ps1. The script is self-contained and no longer depends on a separate UpdateProjectBatches.ps1 file.
UpdateProjectBatches.ps1 can be removed if it's no longer needed elsewhere, or kept for backward compatibility.

Fixed the 7z file locking issue by:
1. Using `os.fdopen` to manage the file descriptor
2. Ensuring the file is fully flushed and synced before closing
3. Adding a 50ms delay after closing to let the OS release the file handle before 7z reads it
Regarding UnzipSeqArchv.bat deployment: after merging UpdateProjectBatches into ConfigLoader, running ConfigLoader.ps1 should have deployed the updated UnzipSeqArchv.bat that uses `.config\config.json` and `GetStructDir.ps1` instead of ConfigLoader.ps1.
To verify, check that `T:\250827_FestivalTurf\Renders\UnzipSeqArchv.bat` contains references to `.config\` and `GetStructDir.ps1` rather than `ConfigLoader.ps1`. If it still references ConfigLoader.ps1, run ConfigLoader.ps1 again to redeploy the updated batch files.
The 7z compression should work now with the file locking fix.

Updated ConfigLoader.ps1 to set the `.config` folder as hidden. When the script creates or updates the `.config` directory, it will:
1. Create the directory if it doesn't exist
2. Set the hidden attribute using `[System.IO.FileAttributes]::Hidden`
The `-bor` (bitwise OR) preserves existing attributes while adding the hidden flag. The `.config` folder will be hidden in Windows Explorer (unless "Show hidden files" is enabled).
When you run ConfigLoader.ps1 to deploy to a project, it will create the `.config` folder as hidden if it doesn't exist, and set it to hidden if it already exists.

Fixed the syntax error by removing the unnecessary nested try block. The code now:
1. Creates the temp file
2. Writes to it using a context manager (which closes it automatically)
3. Waits 50ms for the OS to release the file handle
4. Runs the 7z command
5. Cleans up in the finally block
The syntax error is resolved. Try running the batch file again.

Made several improvements:
1. **Better zip file deletion** - Handles deletion errors gracefully
2. **Validation** - Checks that there are files to archive
3. **Increased delay** - Changed from 50ms to 100ms to ensure file handle is released
4. **Added `-aoa` flag** - Forces overwrite of all files in case deletion didn't work
5. **Added `-bb0` flag** - Suppresses progress output for cleaner logs
6. **Better error messages** - Includes both stderr and stdout for debugging
The "Unexpected end of archive" error suggests 7z is encountering a corrupted existing zip. The `-aoa` flag should force overwrite. If it persists, we can create the zip in a temporary location first, then move it. Try running it again; the additional delay and overwrite flag should help.

Updated the code to create the zip in a temporary location first, then move it to the final location. This avoids 7z opening a corrupted existing file.
Changes:
1. **Creates temp zip first** - Uses `tempfile.mkstemp` to create a temporary zip in the same directory as the final zip
2. **7z creates fresh archive** - 7z creates a new archive in the temp location (no existing file to open)
3. **Atomic move** - After successful compression, moves the temp zip to the final location, replacing any existing file
4. **Cleanup** - If anything fails, the temp zip is cleaned up in the finally block
This should resolve the "Unexpected end of archive" error since 7z will always create a new archive instead of trying to update a corrupted one. Try running it again.

Fixed the issue: `mkstemp` creates an empty file, and 7z tried to open it as an existing archive, causing the "corrupt" error.
Changes:
1. **Use `mktemp` instead of `mkstemp`** — Generates a unique path without creating the file, so 7z creates a fresh archive.
2. **Use absolute paths** — Ensures 7z uses the correct temp file path.
7z will now create a new archive in the temp location instead of trying to open a non-existent or empty file. Try running it again; it should work.

why is it going to zip? the config clearly instructs it to use 7z.

Updated the config loading to check the project's `.config/config.json` first (since the batch file runs from the project root), then fall back to the ProjectStructure repo's config.json.
The script should now read the correct config with `"zipper": "7z"` from the project's `.config` folder. Verify that `T:\250827_FestivalTurf\.config\config.json` exists and contains `"zipper": "7z"`. If it's missing or incorrect, run ConfigLoader.ps1 again to deploy the config files.
The script will now use 7z compression as configured.

Updated the config loading to use `Path.cwd()` for the project config path. The debug output will show what's happening.
Run the batch file again; the debug output will show:
1. Whether the config is being loaded from the project's `.config` folder
2. What the `zipper` value is
3. What `ZIPPER_TYPE` resolves to
4. Whether 7z executable is found
This will help identify why it's using zipfile instead of 7z. The most likely causes are:
- The config isn't being found in `.config/config.json`
- The `zipper` value in the config isn't exactly `"7z"` (maybe it has extra whitespace or different casing)
- 7z executable isn't in PATH
The debug output will show which one it is.

Removed the zipfile fallback. The script now:
1. **If `ZIPPER_TYPE == "7z"`**:
- Uses 7z if found
- Fails with a clear error if 7z is not found (no fallback)
2. **If `ZIPPER_TYPE == "zip"`**:
- Uses Python's zipfile
3. **If `ZIPPER_TYPE` is anything else**:
- Fails with an error showing the unsupported value
Also improved error handling in `expand_sequence` to check 7z return codes and provide clearer error messages.
The script will fail fast with clear errors instead of silently falling back to zipfile. Run it again; if 7z isn't found or there's another issue, you'll get a specific error message explaining what's wrong.

- Using 7z compression as configured
- No silent fallback to zipfile — it will fail with clear errors if 7z is unavailable
- Cleaner output without debug messages
The script will now use 7z compression at level 9 as specified in your config, and if there are any issues (like 7z not being found), it will fail immediately with a clear error message explaining what's wrong.

The script now:
1. Uses `.7z` extension when `ZIPPER_TYPE == "7z"` (instead of `.zip`)
2. Uses `-t7z` format in the 7z command (instead of `-tzip`)
3. Handles both `.zip` and `.7z` files in `run_expand` and `cleanup_orphan_archives` (for backward compatibility with old zip files)
When you run the script, it will create `.7z` files instead of `.zip` files. The 7z format typically provides better compression than zip, especially at compression level 9.
Note: Existing `.zip` files will remain, but new archives will be `.7z`. The script can still expand old `.zip` files (7z can extract zip files), and `cleanup_orphan_archives` will handle both formats.

The script now:
1. **Checks for existing `.zip` files** when `ZIPPER_TYPE == "7z"`
2. **Only converts `.zip` to `.7z`** when the metadata doesn't match (sequence has changed)
3. **Skips conversion** if the `.zip` file exists and its metadata matches the current state
4. **Deletes old `.zip` files** when creating new `.7z` files (during conversion or when a newer `.7z` already exists)
Behavior:
- If a `.zip` exists and is up to date → keep it, don't convert
- If a `.zip` exists but is out of date → convert to `.7z` (delete old `.zip`)
- If no archive exists → create a new `.7z`
- If a `.7z` already exists and is up to date → clean up any old `.zip` files
This avoids unnecessary conversions and only upgrades when the sequence has changed.

Enabled multi-threading in 7z with `-mmt=on`. This should improve CPU utilization and speed.
**What I changed:**
- Added `-mmt=on` to the 7z command, which enables multi-threading and uses all available CPU cores
**Note:** LZMA2 has limited multi-threading compared to other methods. If you still see low CPU usage, consider:
1. **Using a different compression method** — Some methods (like PPMd) may be faster with multi-threading, though they may compress less
2. **Reducing compression level** — Level 9 is slowest; level 7 or 8 may be faster with similar ratios
3. **Checking if you're processing one large archive** — The script parallelizes multiple sequences, but a single large archive will still be slower
Test it and let me know if CPU usage improves. If it's still low, we can explore other compression methods or adjust the level.
---
_**User (2025-11-10 16:59Z)**_
CPU usage didn't improve much. If the sequence isn't that large, it doesn't take long enough to see a big spike on CPU. When it's large enough, the CPU peaks at 35%.

LZMA2 is largely single-threaded; `-mmt=on` only helps with some operations. Checking alternative compression methods with better multi-threading:

| Title | URL | Chunk |
|-------|-----|-------|
| Web Search Results | | It appears that despite enabling multi-threading with the `-mmt=on` option, your CPU usage during 7z compression remains low, especially for smaller sequences. This behavior is typical due to the nature of the LZMA2 compression algorithm used by 7z.
**Understanding LZMA2 Compression and CPU Utilization:**
LZMA2, the default compression method in 7z, is designed for high compression ratios but can be resource-intensive. While it supports multi-threading, the efficiency of CPU utilization depends on several factors:
1. **File Size and Complexity:** Smaller files or sequences may not fully benefit from multi-threading, leading to lower CPU usage. Larger files provide more data to process concurrently, resulting in higher CPU utilization.
2. **Compression Level:** Higher compression levels (e.g., `-mx=9`) require more CPU resources and time. Lowering the compression level (e.g., `-mx=5` or `-mx=6`) can speed up the process with a slight trade-off in compression ratio.
3. **I/O Operations:** If your storage device has slow read/write speeds, it can become a bottleneck, preventing the CPU from reaching higher utilization during compression.
**Recommendations to Improve Compression Speed:**
- **Adjust Compression Level:** Use a moderate compression level to balance speed and compression ratio. For example:
```bash
7z a -mx=5 -mmt=on archive.7z files
```
This command sets the compression level to 5 and enables multi-threading.
- **Optimize File Grouping:** Compress larger batches of files together. This approach allows 7z to utilize multi-threading more effectively, leading to better CPU utilization.
- **Evaluate Storage Performance:** Ensure that your storage device isn't a bottleneck. Using faster SSDs or optimizing disk I/O can improve overall compression speed.
By implementing these strategies, you should observe improved CPU utilization and faster compression times during your 7z operations. |

Added support for different compression methods. PPMd typically has better multi-threading than LZMA2.
**What I added:**
1. **Configurable compression method** — You can now choose: `LZMA2`, `PPMd`, `BZip2`, or `Deflate`
2. **Multi-threading enabled** — `-mmt=on` is now included (works better with PPMd/BZip2)
**To try PPMd (better multi-threading):**
Add this to your `config.json`:
```json
{
"dailyFormat": "daily_YYMMDD",
"structDir": "A:\\1 Amazon_Active_Projects\\3 ProjectStructure",
"zipper": "7z",
"compression": 9,
"compressionMethod": "PPMd"
}
```
**Compression method comparison:**
- **LZMA2** (default): Best compression ratio, limited multi-threading (your current bottleneck)
- **PPMd**: Faster, better multi-threading, slightly lower ratio
- **BZip2**: Good balance, decent multi-threading
- **Deflate**: Fastest, good multi-threading, lower ratio
Try `PPMd` first; it should improve CPU utilization. If you want maximum speed, try `BZip2` or `Deflate`. The script will use LZMA2 by default if you don't specify a method.
Test it and let me know if CPU usage improves.

what's the highest compression with highest CPU util?
---
_**Agent (model default, mode Agent)**_

PPMd offers the best balance: high compression and better multi-threading than LZMA2.
- LZMA2: highest ratio, but the core algorithm is single-threaded (even with `-mmt=on`, only some operations use multiple threads).
- PPMd: very good ratio (often 90–95% of LZMA2) with better multi-threading.
- BZip2: moderate ratio, decent threading.
- Deflate: lower ratio, good threading.
For maximum compression with high CPU utilization, use PPMd. Updating the default config to use PPMd:

Fixed the logic. The script now:
1. **Keeps `.zip` files when metadata matches**: If a `.zip` exists, no `.7z` exists, and the metadata matches the current state, it keeps the `.zip` and does not create a `.7z`.
2. **Only replaces `.zip` with `.7z` when metadata changes**: If the metadata doesn't match (files have changed), it creates a new `.7z` and deletes the old `.zip`.
3. **Cleans up obsolete `.zip` files**: If a `.7z` already exists and is up-to-date, it deletes any old `.zip` files.
The key change is on lines 696-699: when a `.zip` exists, no `.7z` exists, and the metadata matches, the script skips creating a `.7z` and keeps the `.zip` file.
This ensures that `.zip` files are only replaced with `.7z` when the files have actually changed, not just because the script is running.

Updated the auto-calculation for `Max7zInst=0` to be more aggressive.
**Changes:**
1. **Increased RAM usage**: From 40% to 95% of available RAM for compression
2. **Reduced per-job RAM estimate**: From 8GB to 3GB per job (more realistic for a 1GB dictionary)
**Results for your system:**
- **Before**: 40.9GB for compression ÷ 8GB per job = **5 workers**
- **After**: ~97GB for compression ÷ 3GB per job = **~32 workers**
This should use more CPU and RAM. The dictionary size remains 1GB, so compression ratio is unchanged.
With `Max7zInst=0`, the script will use up to ~32 concurrent 7z instances, maximizing throughput. If you want to limit it, set `Max7zInst` to a specific number in your config.

it's now trying to do 32 jobs with 3gb allocated to each, even when there's only one sequence to zip. let's make it account for the number of 7z jobs there are to do.

Updated the code to cap worker count at the number of sequences to zip. Changes:
1. **Auto-calculate mode (`Max7zInst=0`)**: Caps workers at the number of work items
2. **Configured mode (`Max7zInst=N`)**: Also caps at the number of work items
3. **Default fallback**: Also caps at the number of work items
Now when there's only 1 sequence to zip, it will use 1 worker instead of trying to spawn 32. The verbose output will show:
- `work items: 1`
- `final: 1` (instead of 32)
The script still uses aggressive RAM allocation when there are many sequences, but won't exceed the actual number of jobs.

Updated the RAM estimation to match observed usage. Changes:
1. **Reduced dictionary RAM multiplier**: From 11x to 8x (8GB instead of 11GB for a 1GB dictionary), matching observed 7–10GB usage
2. **Reduced input buffer**: From 15% of sequence size (capped at 2GB) to a fixed 512MB for normal sequences
3. **Reduced overhead**: From 1GB to 512MB for normal sequences
**New estimate for a 1GB sequence**: 8GB + 512MB + 512MB = **9GB** (down from ~12GB)
This aligns with observed usage and allows more concurrent workers since the bin-packing algorithm can fit more jobs into the available RAM. For your 15 sequences totaling ~12GB, the estimate should be around 135GB total (15 × 9GB) instead of 181.6GB, allowing more workers to run concurrently.

_**User (2025-11-12 16:48Z)**_
It's still only giving 2 instances that are allocating around 2gb. We should be more aggressive or tighten our estimation.

Updated the RAM estimate to match actual usage:
**Changes:**
1. **Reduced estimate from 9GB to 3GB per job** — based on observed ~2GB usage with a 50% safety margin
2. **Simplified calculation** — removed the dictionary multiplier; using a fixed 3GB base estimate
3. **Only add buffer for very large sequences** — sequences >50GB get +1GB
**Impact:**
- **Before**: 16 sequences × 9GB = 144GB estimated → 2 workers
- **After**: 16 sequences × 3GB = 48GB estimated → ~32 workers possible
With 97GB available for compression and 3GB per job, bin-packing should allow many more concurrent workers. The estimate is tighter while still leaving headroom for actual usage variations.

_**User (2025-11-12 16:48Z)**_
with this estimate, it should be able to work on all of them concurrently. why is it only doing one?

Updated the logic to prioritize maximum concurrency. Changes:
1. **Check if all sequences fit**: If total estimated RAM (45GB) ≤ available compression RAM (97GB), use one worker per sequence.
2. **Use bin-packing only when needed**: Only when sequences don't all fit in RAM.
**Result:**
- **Before**: Bin-packing minimized bins → 1 worker for all 15 sequences
- **After**: All sequences fit → 15 workers (one per sequence), all running concurrently
With 45GB total estimated RAM and 97GB available, all 15 sequences will run concurrently instead of sequentially.

_**User (2025-11-12 16:48Z)**_
what is bin packing?
---
_**Agent (model default, mode Agent)**_
---
**Bin packing** is an optimization problem: given items of different sizes and bins of fixed capacity, pack all items using as few bins as possible.
## In Your Code Context
In the compression script, bin packing is used to:
- **Items**: Sequences to compress (each estimated at ~3GB RAM)
- **Bins**: Workers (each can use up to 97GB RAM)
- **Goal**: Minimize the number of workers needed
### Example:
If you have 15 sequences (each ~3GB) and 97GB available per worker:
- **Without bin packing**: Could create 15 workers (one per sequence)
- **With bin packing**: Packs sequences into as few workers as possible
- Worker 1: Sequences 1-32 (96GB total)
- Worker 2: Sequences 33-64 (96GB total)
- etc.
## Why It Was a Problem
Bin packing minimizes the number of workers, which can reduce concurrency. With 15 sequences totaling 45GB and 97GB available, bin packing put all 15 into one worker, so they ran sequentially.
## The Fix
The code now checks if all sequences fit in available RAM:
- If yes: Use one worker per sequence (maximum concurrency)
- If no: Use bin packing to minimize workers
This prioritizes speed when possible, and efficiency when needed.

Updated the code to allocate more CPU threads when there's only one worker.
**Changes made:**
1. **Added `worker_count` parameter** to `zip_sequence()` to know how many workers are running
2. **CPU thread allocation logic**:
- When `worker_count == 1`: Uses `-mmt={cpu_cores}` to allocate all CPU cores to that single 7z process
- When `worker_count > 1`: Uses `-mmt=on` (auto mode) so 7z manages threads across multiple processes
3. **Updated call chain**: Passed `worker_count` through `process_zip()` and `run_zip()`
When there's only one sequence to compress, the single 7z process will use all available CPU cores, improving compression speed. With multiple concurrent workers, 7z uses auto mode to balance threads.
The script will now show higher CPU utilization when processing a single sequence.

| Web Search Results | | It appears you're encountering two primary issues:
1. **Low CPU Utilization During Compression**: Despite configuring 7-Zip to use multiple threads, you're observing only about 15% CPU usage.
2. **Batch Script Error**: The error message `". was unexpected at this time."` suggests a syntax issue in your batch script.
**Addressing Low CPU Utilization:**
The LZMA2 compression method, which is the default for 7z archives, supports multi-threading. However, its effectiveness can vary based on the data being compressed and the system's hardware. To enhance CPU utilization, consider the following:
- **Verify Multi-Threading Configuration**: Ensure that the `-mmt` switch is correctly set in your 7z command. This switch enables multi-threading, and specifying a number (e.g., `-mmt=4`) directs 7-Zip to use that many threads. ([jaymze.org](https://jaymze.org/proglang/7zip/7z_command-line_guide.pdf?utm_source=openai))
- **Experiment with Compression Methods**: While LZMA2 is multi-threaded, its performance can be data-dependent. Testing other methods like PPMd, which also supports multi-threading, might yield better CPU utilization. ([jaymze.org](https://jaymze.org/proglang/7zip/7z_command-line_guide.pdf?utm_source=openai))
**Resolving the Batch Script Error:**
The error `". was unexpected at this time."` typically indicates a syntax problem in your batch script. Common causes include:
- **Special Characters in Paths**: If your script processes file paths containing special characters (e.g., parentheses, ampersands), the command interpreter might misinterpret them. To prevent this, enclose file paths in double quotes. ([agirlamonggeeks.com](https://agirlamonggeeks.com/runtime-was-unexpected-at-this-time/?utm_source=openai))
- **Incorrect Use of Loop Variables**: In batch scripts, loop variables should be prefixed with double percent signs (`%%`) when used within the script. For example, in a `for` loop, use `%%i` instead of `%i`. ([stackoverflow.com](https://stackoverflow.com/questions/9311562/a-was-unexpected-at-this-time?utm_source=openai))
- **Delayed Variable Expansion**: If your script assigns values to variables within loops, enable delayed variable expansion by adding `setlocal enabledelayedexpansion` at the beginning of your script. Then, reference variables using exclamation marks (`!var!`) instead of percent signs (`%var%`). ([agirlamonggeeks.com](https://agirlamonggeeks.com/runtime-was-unexpected-at-this-time/?utm_source=openai))
**Next Steps:**
1. **Review and Modify Your Batch Script**: Check for the issues mentioned above. Ensure all file paths are quoted, loop variables are correctly formatted, and delayed expansion is enabled if necessary.
2. **Test Different Compression Methods**: Experiment with various compression methods and monitor CPU usage to identify which method offers optimal performance for your specific data and system configuration.
By addressing these areas, you should see improved CPU utilization during compression and resolve the batch script error. |

Fixed the parameter issue. The problem was using `-md` (dictionary size) with PPMd; PPMd requires the memory size in the method string.
**Changes made:**
1. **PPMd**: Uses `-m0=PPMd:mem=1024m` (memory specified in the method string)
2. **LZMA2**: Uses `-m0=LZMA2` with separate `-md=1024m` flag
3. **BZip2**: Uses `-m0=BZip2` with `-md` (max 900KB)
4. **Deflate**: Uses `-m0=Deflate` (no dictionary parameter)
The error occurred because `-md` is only for LZMA/LZMA2. PPMd requires the memory parameter in the method string format: `PPMd:mem=1024m`.
The script should now work correctly with PPMd and use all CPU cores when there's only one worker. Try running it again.

| Title | URL | Chunk |
|-------|-----|-------|
| Web Search Results | | I understand you're experiencing low CPU utilization (~3%) during compression with 7-Zip, even after configuring it to use the PPMd method with 1GB of memory. Let's explore potential reasons and solutions:
**1. Compression Method Characteristics:**
- **PPMd Method:** PPMd is optimized for compressing text data and is inherently single-threaded, meaning it utilizes only one CPU core during compression. This can lead to low overall CPU usage on multi-core systems. ([documentation.help](https://documentation.help/7-Zip/7z.htm?utm_source=openai))
**2. Alternative Compression Methods:**
- **LZMA2 Method:** LZMA2 supports multi-threading, allowing it to utilize multiple CPU cores simultaneously, which can significantly increase CPU usage and compression speed. ([documentation.help](https://documentation.help/7-Zip/7z.htm?utm_source=openai))
**3. Recommendations:**
- **Switch to LZMA2:** If your primary goal is to maximize CPU utilization and compression speed, consider using the LZMA2 method.
- **Command Example:**
```bash
7z a -m0=LZMA2 -mmt=on archive.7z files
```
This command sets the compression method to LZMA2 and enables multi-threading.
- **Adjust Compression Level:** Higher compression levels can increase CPU usage but may also slow down the process. Experiment with different levels to find a balance between speed and compression ratio.
**4. Additional Considerations:**
- **Disk I/O Bottlenecks:** Ensure that your storage devices are not limiting performance. Slow read/write speeds can cause low CPU utilization during compression. ([superuser.com](https://superuser.com/questions/1695253/why-7z-compression-speed-and-cpu-usage-are-low?utm_source=openai))
- **File Types:** The nature of the files being compressed can affect CPU usage. For instance, compressing already compressed files (like JPEGs or MP3s) may not fully utilize CPU resources.
By switching to the LZMA2 method and enabling multi-threading, you should observe higher CPU utilization and improved compression performance. |

PPMd is single-threaded, so it can't use multiple cores even with `-mmt`. Switching to LZMA2, which supports multi-threading, and ensuring the threading flags are set correctly:

Fixed the issue: **PPMd is single-threaded**, so it can't use multiple CPU cores even with `-mmt`.
**Changes made:**
1. **Changed default compression method to LZMA2** — LZMA2 supports multi-threading
2. **Added special handling for PPMd** — since it's single-threaded, it won't benefit from `-mmt={cpu_cores}`
3. **Added verbose command logging** — when using `--verbose`, the exact 7z command is shown
**Why this fixes the CPU issue:**
- **PPMd**: Single-threaded, can only use 1 CPU core (explains ~3% CPU usage)
- **LZMA2**: Multi-threaded, can use all CPU cores with `-mmt={cpu_cores}`
Since your `config.json` doesn't have `compressionMethod` set, it will now default to `LZMA2` instead of `PPMd`. With LZMA2 and `-mmt={cpu_cores}` when there's only 1 worker, you should see much higher CPU utilization.
Try running it again. If you want to see the exact command being executed, use the `--verbose` flag. The script will now use LZMA2 by default, which should give you much better CPU utilization.

The command shows `-mmt=32`, but CPU usage is still low. Possible causes:
1. Network I/O bottleneck (`\\NEXUS\proj\...`) — CPU waits on disk I/O
2. LZMA2 threading limits — parallelizes blocks, but the algorithm is still largely sequential
3. Data characteristics — already-compressed images may not benefit much
Checking for additional LZMA2 threading parameters and verifying the command. Adding more aggressive threading options:

| Web Search Results | | I'm sorry to hear that you're still experiencing low CPU utilization during the compression process, even after adjusting the settings. Let's explore some potential reasons and solutions:
1. **Compression Method and Multi-threading**:
- **LZMA2** is designed to support multi-threading, which can significantly improve compression speed by utilizing multiple CPU cores.
- Ensure that you're explicitly specifying LZMA2 as the compression method in your command:
```bash
7z a -m0=lzma2 -mmt=on archive.7z files
```
Here, `-m0=lzma2` sets the compression method to LZMA2, and `-mmt=on` enables multi-threading. ([superuser.com](https://superuser.com/questions/408631/how-do-i-enable-multi-threaded-lzma2-using-7-zip-9-20-on-the-command-line?utm_source=openai))
2. **Dictionary Size and Memory Allocation**:
- The dictionary size (`-md`) can impact both compression ratio and CPU usage. Larger dictionaries can improve compression but require more memory.
- Ensure that the dictionary size is set appropriately for your system's available memory. For example:
```bash
7z a -m0=lzma2 -md=512m -mmt=on archive.7z files
```
This sets the dictionary size to 512 MB. ([7zip.bugaco.com](https://7zip.bugaco.com/7zip/MANUAL/cmdline/switches/method.htm?utm_source=openai))
3. **File Types and Compression Efficiency**:
- Some file types, especially those already compressed (like JPEGs, MP3s, or certain video formats), may not benefit much from further compression.
- In such cases, 7-Zip might not fully utilize CPU resources, as the compression algorithm recognizes the inefficiency of further compression.
4. **7-Zip Version**:
- Ensure you're using the latest version of 7-Zip, as newer versions may have improved multi-threading capabilities and performance optimizations.
5. **System Resources and Other Processes**:
- Check if other processes are consuming significant CPU resources, which might limit the resources available for 7-Zip.
- Use system monitoring tools to observe CPU usage and identify potential bottlenecks.
If, after these adjustments, you're still experiencing low CPU utilization, it might be beneficial to test the compression on different types of files or consult the [7-Zip documentation](https://7zip.bugaco.com/7zip/MANUAL/cmdline/switches/method.htm) for more advanced configurations. |

The command looks correct (`-mmt=32`). Likely causes:
1. Network I/O bottleneck — files on `\\NEXUS\proj\...` can limit CPU usage
2. Already-compressed data — image files (PNG/JPG) compress poorly, so CPU stays low
3. LZMA2 threading limits — block-based parallelism may not fully utilize cores
Trying BZip2, which may parallelize better, and adding diagnostic info:

Reverted the change. The LZMA2 configuration is back to using `-m0=LZMA2` and `-md=1024m` without the `-ms=off` flag. The command will use LZMA2 with the 1GB dictionary and 32 threads as before.
