openmp

I have the following problem: I am trying to set 4 threads in parallel areas, but I see that only 2 are working. Ed. The vari ... le "test" everything works as it should, and I see that all 4 threads work. Tell me, please, what kind of mistake did I make?

We set the task to write a couple of algorithms in C++ using OpenMP. Since I have a Macbook, I had to install the Clion IDE a ... o set it. I must say that I have not worked with C++ or C ++ before. OpenMP. OS: macOS Catalina Beta Version 10.15.6 (19G36e)

I have about a trace. code for (;;) { do { //тут нужно расспараллелить } } I would like to parallelize what is i ... hat we need to create two threads that will execute this code, while they do not need to be deleted and created 100500 times.

There is a task to make a parallel implementation of quick sorting, but I get it so that the parallel algorithm works many ti ... ; double time = end_time - start_time; printf("%f", (double)time / CLOCKS_PER_SEC); delete[] A; cin.get(); }

Reading a few things on the topic, I realized that they are not the same thing, so I would like to find out: What is the difference between parallelism and concurrency in processes?

I wanted to know what I can do to decrease runtime using Openmp threads. I made a code to add the values of a vector of size ... on(+:soma) for(i=0; i<N; i++){ soma += vet[i]; } printf("Resultado: %ld\n", soma); return 0; }
