[mpich-discuss] MPI fail on 20 processes, but not on 10.

5 Jan 2014

      Hi.
I have created an application. This application fails on MPI error.
Assertion failed in file src/mpid/ch3/channels/nemesis/src/ch3_progress.c
at line 640: pkt->type >= 0 && pkt->type < MPIDI_NEM_PKT_END
 internal ABORT - process 0

Scenario:
Master receives messages from slaves.
Each slave sends data using MPI_Send.
Master receives using MPI_Irecv and MPI_Recv.

There are another errors in out*.log files.
Application doesn't *fail* with 10 processes, but fails with 20.

execute command:
mpiexec.hydra -genvall -f MpiConfigMachines1.txt -launcher=rsh -n 20
/home/anatol-g/Grape/release_under_constr_MPI_tests_quantum/bin/linux64/rhe6/g++4.4.6/debug/mpi_rcv_any_multithread
100000 1000000 -1 -1 1 out

Please help,

Regards,
Anatoly.
