[mpich-discuss] Error in dynamically spawned processes

[Mahesh Doijade]

Hi,
    I am dynamic creating process using MPI_Comm_spawn_multiple(), the code
runs for several inputs without any error but for some larger input size it
is throwing this error as given below.


Fatal error in PMPI_Barrier: A process has failed, error stack:
PMPI_Barrier(426).........: MPI_Barrier(comm=0x84000002) failed
MPIR_Barrier_impl(333)....: Failure during collective
MPIR_Barrier_impl(315)....:
MPIR_Barrier_intra(83)....:
dequeue_and_set_error(823): Communication error with rank 0
