from 1 to
numprocs? This may be important when they work as arguments in
mpi_allgatherv subroutine.
These questions may be too simple for MPI professionals, but I do not have
much experience on this. Thus I am sincerely eager to get some comments and
suggestions from you. Thank you in advance!

put into YVAR in a non-consecutive way. for instance, if I have 4
processors, the first element in YVAR is from rank 0, second from rank 1
..fourth from rank 3, and then fifth from rank 0 again, sixth from rank
1 again... But I will try your suggestion.
Thanks.

(2s). I used
mpi_wtime to count the time.
I think mpi_send and mpi_recv are blocking subroutines and thus no
additional mpi_barrier is needed. Can anybody tell me what is the reason
for this phenomena? Thank you very much.
