Fatal error in MPI_Send: Other MPI error, error stack:

[manhnt181]

Hi everyone,
I've been using COAWST model with new version (3.7), however, I got the error related to the MPI like that:

Code: Select all

Fatal error in MPI_Send: Other MPI error, error stack:
MPI_Send(173)..................: MPI_Send(buf=0x4768f30, count=4, MPI_INTEGER, dest=0, tag=31, comm=0xc400002c) failed
MPIDI_EagerContigShortSend(262): failure occurred while attempting to send an eager message
MPIDI_CH3_iStartMsg(36)........: Communication error with rank 0

This error is attached in the attachments.
Please help me to resolve this problem!
Any suggestions will be appreciated!
Many thanks,

i see "MCT::m_SparseMatrixPlus::initFromRoot_:: FATAL--length of vector y different from row count of sMat.Length of y = 128250 Number of rows in sMat = 127516
01E.MCT(MPEU)::die.: from MCT::m_SparseMatrixPlus::initFromRoot_()"
so this is probably due to the scrip weights not being computed correctly. most likely you entered the incorrect grid size for swan in the scrip.in file.
can you please post this issue here:
