[petsc-users] About MPIRUN

[김성익]

I already done VecAssemblyBegin/End().

However, only mpirun case these outputs are represented.
There are more error outputs as below.
  --------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_SELF
with errorcode 73.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------

[ubuntu:02473] 3 more processes have sent help message help-mpi-api.txt /
mpi-abort
[ubuntu:02473] Set MCA parameter "orte_base_help_aggregate" to 0 to see all
help / error messages

Could this be the cause of the former petsc error??


Thanks,
