Re: cmd launching FF through MS-MPI never exits

Alex Granovsky


this is a known bug of MS MPI version 7.1 and above with no known
fix at Firefly level.

Namely, MS MPI fails to properly detect that Firefly job has terminated.

I'd suggest you to downgrade to MS MPI version 5, which does not have
this annoying bug. Alternatively, you can try other implementations
of MPI for Windows or submit a bug report to Microsoft.  

Kind regards,
Alex Granovsky

This occurs both in smpd -d and via MsMpiLaunch Service. No problems when I use MS-MPI with other applications. I also remember that in the past I have been using older versions of MS-MPI within Firefly, getting no problems at all.
