| rami17 <rami17@rami17.net>: May 03 12:26AM -0400 Hello.... Please read this: "Just as with normal thread pool usage, the main program thread may create Tasks that will get queued on the global queue (e.g. Task1 and Task2) and threads will grab those Tasks typically in a FIFO manner. Where things diverge is that any new Tasks (e.g. Task3) created in the context of the executing Task (e.g. Task2) end up on a local queue for that thread pool thread." Read more here: http://www.danielmoth.com/Blog/New-And-Improved-CLR-4-Thread-Pool-Engine.aspx You will notice that there is a contention on the global queue from the producer threads and from the consumer threads on the Microsoft CLR Threadpool engine, so that's not good. But please look at the source code of my Threadpool engine that scales well, it does eliminate the contention on the consumer threads side by using technics such as lock-striping and other technics.. And my efficient threadpool that scales well supports the following: - Now it can use processor groups on windows, so that it can use more than 64 logical processors and it scales well. The following have been added to my efficient Threadpool engine: - The worker threads enters in a wait state when there is no job in the concurrent FIFO queues - for more efficiency - - You can distribute your jobs to the worker threads and call any method with the threadpool's execute() method. - It uses work-stealing to be more efficient. - You can configure it to use stacks or FIFO queues , when you use stacks it will be cache efficient. - Now it can use processor groups on windows, so that it can use more than 64 logical processors and it scales well. - Now it distributes the jobs on multiple FIFO queues or stacks so that it scales well. - You can wait for the jobs to finish with the wait() method. - It's NUMA-aware and NUMA efficient.

| rami17 <rami17@rami17.net>: May 02 11:58PM -0400 Hello.... The readme file of my scalable SeqlockX was updated, you will find it inside the zip file.. My scalable SeqlockX elminates the weaknesses of the classical Seqlock (sequential lock) that is "livelock", so it avoids livelock when there is more writers, so my scalable SeqlockX is a powerful sychronization mechanism. Please download it again from: https://sites.google.com/site/aminer68/scalable-seqlockx Thank you, Amine Moulay Ramdane. |
| rami17 <rami17@rami17.net>: May 02 10:38PM -0400 Hello... I have just finished my project of my Object oriented library to do stackful coroutines.. You can download the new version 2.0 from: https://sites.google.com/site/aminer68/object-oriented-stackful-coroutines-library-for-delphi-and-freepascal . Also i am actually finishing a project that is a GUI archiver that looks like 7Zip GUI archiver, it is an archiver that uses my Parallel archiver and that supports Parallel Zstandard and Parallel LZ4 and Parallel LZMA, and that supports windows processor groups and that works on Win32 and Win64. My other projects that i have finished are actually more stable and really fast, you can be more confident with them, please feel free to download them from: https://sites.google.com/site/aminer68/ Hope you will be happy with my Delphi and FreePascal projects ! Thank you, Amine Moulay Ramdane. |
| rami17 <rami17@rami17.net>: May 02 10:02PM -0400 Hello, My Object oriented Stackful coroutines library for Delphi and FreePascal version 2.0 is here.. I have completly rewritten the 64 bit and 32 bit library for FPC and the 32 bit library for Delphi XE, i have enhanced it and you have to take a look at it , it is now really good and really fast and more stable. Now it is working with Windows and Linux and MacOSX on (x86), i have just booted on Linux and compiled it with FreePascal on Linux and it is working correctly and it is really good. Please take a look at the source code to learn more how to use it. You can download the new version 2.0 from: https://sites.google.com/site/aminer68/object-oriented-stackful-coroutines-library-for-delphi-and-freepascal . Thank you, Amine Moulay Ramdane. |
