@dutta-alankar : I haven't been able to determine why our experiences are differing, but would you try the following?
cd $CHPL_HOME/runtime
make clean
make DEBUG=1 OPTIMIZE=0 # was, incorrectly, "DEBUG=1 OPTIMIZE=0"
and if that works, recompile and re-run your program, and hopefully we'll get more output from GASNet about why that call is failing?
One other thing that feels very paranoid, but I want to make sure of: I think we've been assuming you're using OpenMPI due to some of the paths and variables that show up in your output, but is there any chance that the mpirun and/or MPI you're using is not OpenMPI?
Thanks,
