Hello,
I'm using openMPI for a paralelization of a fortran90 code. I came accross
an error - when I try to send a matrix 400x450 of real*8 (double) I get
following error:
[masada:05620] *** An error occurred in MPI_Recv
[masada:05620] *** on communicator MPI_COMM_WORLD
[masada:05620] *** MPI_ERR_TRUNCATE: message truncated
[masada:05620] *** MPI_ERRORS_ARE_FATAL (goodbye)
forrtl: error (78): process killed (SIGTERM)
I understand that the amount of data that can be send by one MPI_SEND call
is somehow limited - what is this limitation? can it be somehow augmented?
best
regards,
Michael
