[OMPI users] CPU use in MPI_recv

2006-06-06 Thread Laurent . POREZ
Hi, I'm using Open-MPI 1.0.2 on a debian system. I'm testing the MPI_recv function with a small C program (source code at the end of the message). And I see that when I'm waiting a message, calling MPI_recv, the CPU is used at 100 %. Is that normal ? Is there other ways to use a recv function
