I think if you boot the mpi on the host machine, and than run your
program with 8 thread (mpirun -np 8 ) , the operating
system will automatically distribute it to the cores.

Also there is profiler called "vampire", I think bought by Intel.. It
create a very extended profile for mpi applications and mpi
communication. It is very useful, I think it is a library, you should
compile your program with vampire option to be able to use it. Also it
has a graphical inter

Hi,
I need to use rank of the mpi processes in my sub functions ( c
language). which one has more cost?;
creating a new variable& and finding the rank in each sub function by:
int mpi_rank;
MPI_Comm_rank(MPI_COMM_WORLD,&mpi_rank);
or finding the rank in main function once,
