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.
I keep getting error messages about MPI_REQUEST_MAX being too small, no matter how large I set it.
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 SHMEM?
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?
Must I use MPIO_Wait() and MPIO_Test()?
Must I modify my code to replace calls to MPIO_Wait() with MPI_Wait() and recompile?
Why do I see “stack traceback” information when my MPI job aborts?
