Hi!

I tried my code on another machine with 4 processors. It works when I put
omp_set_num_threads(2) but only with omp_set_dynamic(true) and I noticed on
htop that only one processor is used per request. When I force the use of 2
processors with omp_set_dynamic(false), it segfaults or deadlocks, as it
does with 3 or 4 processors and on my 2 processors machine. So I didn't
solve the problem yet :-((.

So, anyone has an idea of the problem?
Thanks
