I am working on an existing application where threads are submitted
concurrently. he is submitting 8 threads together and then he is waiting
for all 8 threads to be finished to submit the next 8 threads. In this way
after every 8 threads he is waiting and a lot of time is being taken for
waiting. Can you me some suggestions how can I skip this waiting after
submitting 8 threads to improve speed. Total number of cpu is 8 so he is
submitting 8 threads at a time.
Submitting threads like this
int nCpus = Environment::Get_No_Of_Cpus(); // ==8
for(z=0; z<21; z++)
{
for (int cpuID=0; cpuID<nCpus; cpuID++)
{
Th = QtConcurrent::run(this, zLayerFunction,z,...,cpuID);
Threads.push_back(Th);
}
//then he after submitting 8 threads, he is waiting for all 8 threads to be
finished to submit the next 8 threads.
for(int th=0; th<Threads.size(); th++ )
{
Threads.at(th).waitForFinished();
Threads.cancel();
}
Threads.clear();
z--;
}
How can i improve the speed so that it doesn't wait. How can I make it
continuous. Any suggestions would be highly appreciated. Thanks Sujan
