use more than one processor in parallel system returns error

[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

bytes received but buffer size is 16

thanks in advance for your helps

what solver are you using .. you need to be using Mumps.

hello fmk
SuperLU is used . your mean the only option for me is Mumps solver ?

[fmk]

yes.

Hello mehdikia2519,

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

Thanks for your help.
