Hello, I am using mpich on Arch on my own desktop computer. Unfortunatly, I don't have Totalview or DDT at hand. OpenMPI has a useful option to pause on an MPI error: mpirun --mca opal_abort_delay 600 -n 4 ... so that I can attach with a debugger and backtrace up into my app. Is there something like that for mpich? What other recommendation could you give for debugging MPI applications (not mpich itself), especially for MPI Ports. I have re-compiled with --enable-g=all. setenv MPICH_DBG FILE setenv MPICH_DBG_LEVEL VERBOSE works, but produces too detailed output, even when $MPICH_DBG_TYPICAL is defined, and also too far away from my application code. Thanks, Florian _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
