In general we do not desire non-MPI process' exit to terminate other processes. It is common to use hydra to launch non-mpi processes and expect each process to proceed independently....

@jmcave I am about to mark this issue as "wontfix". Launch a set of processes with mixed MPI processes (i.e call `MPI_Init`) and non-MPI processes are incorrect usage. The MPI...

1. Identify a list of tests that are already ported to `test/mpi/io` 2. Identify a list of tests in `romio/test` that need to be ported 3. Remove the tests in...

We currently have very little support for dynamic window optimizations. I am renaming this ticket since detecting or creating mechanism for optimized shm path for dynamic window is the the...

Looks like we can pass info hints "shmem" to `MPI_Win_alloc`. If that enables shared memory RMA, then that is a much easier option to add to the tests.

Could you upload your complete test code?

Is your application multithreaded? I suspect you have called `MPI_Finalize` in one thread thus resulting in another thread accessing MPI after `MPI_Finalize`. Make sure to run a thread barrier before...

Try to build mpich with `--enable-g=all` (configure option). Then set environment variables (ref: https://github.com/pmodels/mpich/blob/main/doc/wiki/design/Debug_Event_Logging.md): ``` export MPICH_DBG_FILENAME="log/dbg-%w-%d.log" export MPICH_DBG_CLASS=ALL export MPICH_DBG_LEVEL=VERBOSE ``` Could you upload the log files?

> That looks fine. If you search `MPI_Finalize` over your entire project code, do you see any other instances?
