Hi Jeff,
Thank you for your email. The program make an MPI_Reduce call as the only form
of explicit communication between machines… I said it was simple because it's
effectively a very trivial distributed computation for me to learn MPI. I am
using the same version, by doing "brew install open
Can you provide any more detail?
Your report looks weird - you said its a simple c++ hello world, but the
executable you show is "pi", which is typically a simple C example program.
Are you using the same version of open MPI on all nodes? Are you able to run n
way jobs on single nodes?
Sen
