Intelli2 <intelli2@mama.com>: Dec 19 06:02PM -0500 Hello, My Parallel Compression Library version 4.25 is here.. It works with C++Builder, because Delphi can be used from C++Builder. Here is C++Builder: https://www.embarcadero.com/products/cbuilder My Parallel Compression Library implements Parallel LZ4 , Parallel LZMA , and Parallel Zstd algorithms using my Thread Pool Engine. - It supports memory streams, file streams and files - 64 bit supports - lets you create archive files over 4 GB , supports archives up to 2^63 bytes, compresses and decompresses files up to 2^63 bytes. - Parallel compression and parallel decompression are extremely fast - Now it supports processor groups on windows, so that it can use more than 64 logical processors and it scales well. - It's NUMA-aware and NUMA efficient on windows - It minimizes efficiently the contention so that it scales well. - It supports both compression and decompression rate indicator - You can test the integrity of your compressed file or stream - Easy programming interface - Full source codes available. Now my Parallel compression library is optimized for NUMA and it supports processor groups on windows and it uses only two threads that do the IO (and they are not contending) so that it reduces at best the contention, so that it scales well. Also now the process of calculating the CRC is much more optimized and is fast, and the process of testing the integrity is fast. I have done a quick calculation of the scalability prediction for my Parallel Compression Library, and i think it's good: it can scale beyond 100X on NUMA systems. Here are the parameters of the constructor: First parameter is: The number of cores you have specify to run the compression algorithm in parallel. Second parameter is: A boolean parameter that is processorgroups to support processor groups on windows , if it is set to true it will enable you to scale beyond 64 logical processors and it will be NUMA efficient. Just look at the Easy compression library for example, if you have noticed it's not a parallel compression library. http://www.componentace.com/ecl_features.htm And look at its pricing: http://www.componentace.com/order/order_product.php?id=4 My parallel compression library costs you 0$ and it's a parallel compression library..

It doesn't impose any additional requirements on the layout of the class, so it doesn't resolve the issue I raised. |
