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.
