Dear Collegues, I've got a question: Is there basically any difference between running an MPI program on Intel Xeon and Core i7 processors?
I heard that since an MPI program is running on Intel Xeon processor, then it's executed in a different way. For example, if you run an MPI program on Intel Xeon processor, then all processes has been launched by mpiexec utility are executed in the order of their ranks e.g. 0,1,2,3,4,5,6,7,... and if you run the program on Intel Core i7 processor, then those processes executed in arbitrary order.
Waiting for your reply.
Cheers, Arthur.
