[mpich-discuss] [mpich2-discuss]How to output debug info?

[Darius Buntinas]

Try setting environment variables and see if that works:

    export MPICH_DBG_FILENAME="log/dbg-%w-%d.log"
    export MPICH_DBG_CLASS=ALL     
    export MPICH_DBG_LEVEL=VERBOSE

Make sure you create the 'log' directory (i.e., mkdir log) first.
