Subject: Help - mpi ocl restore session

Greetings JTR wizards- 

I humbly bow before your knowledge again, in quest of jtr enlightenment.... 

I use John the Ripper, version 1.8.0.2-bleeding-jumbo_mpi [linux-x86-64-opencl] 

I can run an mpirun opencl session just fine and all sessions complete just fine. My only  trouble is with session restore and only if it involves remote hosts. I can resume a session if there is not a remote host. However, if I terminate a session with a one or more remote hosts using
 "killall mpirun", "kill HUP" or Ctrl-c and try to restore the session, only one core or one GPU will resume.

I use the following syntax to restore:

mpirun --host ub0 --host ub1 --host ub2 ./john --restore

I also have version 1.8.0.2-bleeding-jumbo_mpi [linux-x86-64-native] and I can
 restore multi host sessions just fine usng:

mpirun -n 32 --hostfile /etc/nodes ./john --restore

Any idea why I'm having so much trouble restoring mpi opencl multi host sessions??

Thanks,
Tony
