performance - Is there a parallel file archiver (like tar)? - Unix ...
From the pigz documentation: "Decompression can't be parallelized, at least not without specially prepared deflate streams for that purpose. As a result, pigz uses a single thread (the main thread) for decompression, but will create three other threads for reading, writing, and check calculation, which can speed up decompression under some ...
parallelism - Are basic POSIX utilities parallelized? - Unix & Linux ...
2020年6月25日 · Finally: parallelization also takes place at process level and a parallelized make could easily run 3x faster than a non-paralelized version. If your platform allows you to switch off CPUs at runtime, I encourage you to switch off n-1 CPUs and compare the results with a multi CPU environment on the otherwise identical machine.

sed - How to wait for execution of parallelized processes and stitch ...
I know about using split and sed for splitting files, and I can't imagine getting the split files to run through a Python script is hard either, but the problem is finding out when all executions of the parallelized programs are complete, and THEN stitching their outputs together into one.
How to use GNU parallel effectively - Unix & Linux Stack Exchange
2015年2月3日 · The decompression is the bottleneck here. If decompression is not parallelized internally, you won't achieve it by yourself. If you have more than one job like that, then of course launch them in parallel, but your pipeline by itself is hard to parallelize.

How to gzip 100 GB files faster with high compression?
2020年12月11日 · I myself needed to compress a larger file of size approx. 256 GB, and I tested gzip, bzip2, xz, and their parallelized versions. In the end, I used pigz .

GNU Parallel Python Semaphore - Unix & Linux Stack Exchange
2020年1月20日 · I have a Python script parallelized through GNU parallel which finds a certain result which I would like to output to a file, which I currently do through standard Python file IO. The issue is that I open this file in each parallelized thread, and the threads are stepping on eachother's toes while writing.
