Hi Diego,
displacements start at 0, so 0 means no displacement, i.e., the
corresponding data starts at the first entry (by default 1 in Fortran)
of the receive field. A displacement of 1 would point to entry number 2.
Btw., MPI does not care how you allocate your fields in Fortran. E.g.,
if yo
dear George, dear all,
thanks for the suggestions, it works now.
I have just put:
IDNodeStartGLOBAL = IDNodeStartGLOBAL -1
but I do not understand why. Can you explain it to me?
Thanks
Diego

I wonder if this is related to the problem reported in

Dear all,
I am a beginner of MPI, right now I try to use MPI_GATHERV in my code, the test
code just gather the value of array A to store them in array B, but I found an
error listed as follows,
'Fatal error in MPI_Gatherv: Invalid count, error stack:
PMPI_Gatherv<398>: MPI_Gatherv failed
fail
