Troubleshooting and Frequently Asked Questions
What are some things I can try to figure out why mpirun is failing?
My code runs correctly until it reaches MPI_Finalize() and then it hangs.
My hybrid code (using OpenMP) stalls on the mpirun command.
I keep getting error messages about MPI_REQUEST_MAX being too small.
I am not seeing stdout and/or stderr output from my MPI application.
How can I get the MPT software to install on my machine?
Where can I find more information about the SHMEM programming model?
The ps(1) command says my memory use (SIZE) is higher than expected.
What does MPI: could not run executable mean?
How do I combine MPI with insert favorite tool here ?
Why do I see “stack traceback” information when my MPI job aborts?
