libthreadable-benchmarks

TLDR

libthreadable is a C++ library for cache-aware, concurrent task execution using
a thread pool with lock-free queues. It simplifies parallel programming by managing
threads and task distribution for performance-critical applications.

Example

#include <threadable/pool.hxx>

int main() {
  // thread pool:
  auto  pool  = fho::pool();
  auto& queue = pool.create();
  auto  token = queue.emplace_back( []() { cout << "task executed!\n"; });
  token.wait();

  // generic ring buffer:
  auto ring = fho::ring_buffer<int>();
  ring.emplace_back(1);
  ring.emplace_back(2);
  ring.emplace_back(3);
  assert(ring.size() == 3);

  for (auto v : ring)
  {
    cout << format("{}\n", v); // prints 1 2 3
  }
  assert(ring.size() == 3);

  for (auto v : ring.consume())
  {
    cout << format("{}\n", v); // prints 1 2 3
  }
  assert(ring.size() == 0);

  return 0;
}

Design Overview

Thread Pool (pool) + Worker Threads (executor):
Manages multiple task queues and worker threads,
orchestrating task distribution to executors running
in dedicated threads via a scheduler.

task Queues (ring_buffer):
Lock-free multi-producer, single-consumer ring buffer
to store tasks.

Ring Iterator (ring_iterator) + Slot (ring_slot):
Support the ring_buffer with efficient random access
and state management for buffer elements.
