use more than one processor in parallel system returns error

Post by mehdikia2519 »

dear fmk
when a model is run in a parallel system with one processor ( i.e. " mpiexec -np 1 OpenSeesSP pushover.tcl " ) , there is no problem but when more than one processor is used ( i.e. " mpiexec -np 2 OpenSeesSP pushover.tcl ") the following errors return

Slave Process Running 1
StaticDomainDecompositionAnalysis::recvSelf - failed to get the Solver
Fatal error in MPI_Recv: Message truncated, error stack:
MPI_Recv(186).....................: MPI_Recv(buf=00E84050, count=4, MPI_INT, src
=0, tag=0, MPI_COMM_WORLD, status=0031F638) failed
MPIDI_CH3U_Receive_data_found(129): Message from rank 0 and tag 0 truncated; 24
bytes received but buffer size is 16

job aborted:
rank: node: exit code[: error message]
0: MEHDI-PC: 123
1: MEHDI-PC: 1: process 1 exited without calling finalize

thanks in advance for your helps

Hello mehdikia2519,

Were you able to fix this issue? I am having the same problem even using Mumps solver.

Thanks for your help.
