I do have these two environment variables set: LD_LIBRARY_PATH=/Users/meredithk/tools/openmpi/lib PATH=/Users/meredithk/tools/openmpi/bin
Running mpirun seems to work fine with a simple command, like hostname: $ )mpirun -n 2 hostname meredithk-mac.corp.fmglobal.com meredithk-mac.corp.fmglobal.com I am trying to run the simple hello_cxx example from the openmpi distribution, compiled as such: mpic++ -g hello_cxx.cc -o hello_cxx It compiles fine, without warning or error. However, when I go to run the example, it stalls on the MPI::Init() command: mpirun -np 1 hello_cxx It never errors out or crashes. It simply hangs. I am using the same mpic++ and mpirun version: $ )which mpirun /Users/meredithk/tools/openmpi/bin/mpirun $ )which mpic++ /Users/meredithk/tools/openmpi/bin/mpic++ Not quite sure what else to check.
