[mpich-discuss] Crash with hydra on MPI_Finalize

[Jain, Rohit]

Hi,

 

I am seeing a crash with mpich2-1.3.3rc1, when application quits. This
is a specific case where all processes are exiting, and they call
MPI_Finalize almost at the same time.

 

# 0    0x08c2bff8: 'MPIR_CommL_forget + 0x28'

# 1    0x08c1ff52: 'comm_delete + 0x1c2'

# 2    0x08c20145: 'MPIR_Comm_release_always + 0x35'

# 3    0x08c5358e: 'MPID_Finalize + 0x2e'

# 4    0x08c27089: 'MPI_Finalize + 0x119'

 

Note that I recently started using hydra with this mpich2 version.
Earlier mpich2 version with mpd works fine. 

 

Is there any difference in how hydra handles finalize?

If so, does application need to change to make it work with hydra?

 

Regards,

Rohit
