我試圖在任何時候限制線程的數量,使其等於最大可用內核的數量。以下是一個合理的方法嗎?有更好的選擇嗎?謝謝!Boost thread_group線程限制器
boost::thread_group threads;
iThreads = 0;
for (int i = 0; i < Utility::nIterations; i++)
{
threads.create_thread(
boost::bind(&ScenarioInventory::BuildInventoryWorker, this,i));
thread_limiter.lock();
iThreads++;
thread_limiter.unlock();
while (iThreads > nCores)
std::this_thread::sleep_for(std::chrono::milliseconds(1));
}
threads.join_all();
void ScenarioInventory::BuildInventoryWorker(int i)
{
//code code code....
thread_limiter.lock();
iThreads--;
thread_limiter.unlock();
}
