[mvapich-discuss] need help：my install are segmentation fault

[Subramoni, Hari]

Hello.

Sorry to hear that you are facing issues. Could you please let us know the following information.


1.       How are you launching the program? Since MVAPICH2 was built for SLURM, you should be launching it with srun

2.       Do you have a back trace of the failure (setting MV2_DEBUG_SHOW_BACKTRACE=2 should print a backtrace).

3.       How many processes, processes per node/nodes are there in your run?

4.       What version of IMB are you using?

Regards,
Hari.
