    well, somebody ask me to build a static dll without dependencies to visual c runtime and visual c++ this should be done with clang and mingw (but now I don't have time) about my repository I added a thread safe fifo queue for highest performance producer-consumer between threads https://github.com/RDP1974/Delphi64RTL check testqueue

    oneapi tbb concurrent hash map when call iterate() does a snapshot copy of the collection and publish it, meantime protecting keys with acc (similar to critical section) btw. concurrent_queue test with 10 threads is 3x quicker than TOmniQueue, and unfortunately TThreadedQueue goes in deadlock

    hi, I wish to not be offtopic, and to be useful anyway there https://github.com/RDP1974/Delphi64RTL I have added concurrent queue, thread safe, from OneApi v2022.1 also a small test there (single thread, create and dispose string, 10M push + 10M pop within 1 sec)(I have not time to do multithread test now) kind regards btw. this repo is a base for a mine custom server reactor+proactor done in Delphi

    updated intel scalable allocator a little change for delphi 12.x please let me know if you found errors kind regards btw. in my test, win11 24h, i9900, in single thread scenario it's identical score with the default mm (D12.3), in multithread scenario it's the fastest among tested

    guess a pool with 100 tthreads, each with a queue fifo receiving messages, also each tthread send messages simultaneously to every all others: then a tthreadqueue without global locking as CRT should be the faster solution? as far I have researched then the spring4d queue lock free seems the fastest solution (but I cannot find it in the source) finally -> OmniThreadLibrary -> TOmniBaseQueue -> Dynamically allocated, O(1) enqueue and dequeue, threadsafe, microlocking queue or TOmniMessageQueue (ring buffer) also I have found a ring buffer from https://blog.grijjy.com/2017/01/12/expand-your-collections-collection-part-2-a-generic-ring-buffer/ please can you suggest me the best code, libraries to achieve consumer-producers between threads? thanks btw.if I have time will do a dll for tbb::concurrent_queue

    please can you test with TThreadedQueue? (with latest 12.3)
  9. RDP1974
    can I ask? the tthreadedqueue it's reliable in delphi 12.3 latest release? or do you suggest omnithread queue? about dictionary same question, or do you suggest spring4d? or other libraries are better than default rtl?

    hi, I have a windows service where I dispatch a custom thread pool, dynamic, using IoCompletionPort api, then I have a component where methods should be called within the servicethread, my question is, do you know if servicethread.queue it is reliable? is this the best method to post things to the main thread in a safer way without incur in race conditions as deadlock? example, this code is called within a thread: TServiceThread.Queue(Service.ServiceThread, procedure begin dothings end); kind regards
