> Hi all,
> My system is a 64 core, with Debian 3.2.57 64 bit, GNU gcc 4.7, kernel
Linux 3.2.0 and OpenMPI 1.8.1.
> I developed an application to matching proteins files using OpenMP
+OpenMPI. I compiled souce code with -fopenmp flag, I set OMP_NUM_THREADS=4
then I ran binary with mpiexec -np 16.
> When the program runs, the top command show me that only 16 core are
used. If I use the previous of OpenMPI (1.6.5) it works fine. Must I set
anything in the new version? Where I wrong?
> Thanks in advance
