MPI_Finalize hangs

[Polykarpos Thomadakis]

Hello,

First of all I would like to thank you for your great work on the ULFM library.

I found out about it at the SC tutorial. I'm trying to run the examples given to us there

under SLURM but I notice the following issues:

1) When running with 2 ranks, after a failure detection the application will terminate without

returning from MPI_Finalize()

2) When running on more than 2 ranks, MPI_Finalize() hangs. In this case I also get

wrong failure detections some times.

Could it be my configuration? I happens every single time. I followed the build instructions

on your website and run with the following flags:

-mca btl tcp,self -mca pml ob1 -mca mpi_ft_detector true

Thank you,

Polykarpos

Also when run outside of slurm on a single node of 40 cores it works correctly.
