Subject: Re: OpenMPI and .rec files?

A clean check on a local system with a very basic setup shows that it is not a generic issue:

---
bofh@...ncher:/opt/JohnTheRipper/run$ rm *rec; mpirun -np 99 ./john --format=raw-md4 /tmp/hashes
--------------------------------------------------------------------------
[[62017,1],34]: A high-performance Open MPI point-to-point messaging module
was unable to find any relevant network interfaces:

Module: OpenFabrics (openib)
  Host: cruncher

Another transport will be used instead, although this may result in
lower performance.
--------------------------------------------------------------------------
Using default input encoding: UTF-8
Loaded 1200 password hashes with no different salts (Raw-MD4 [MD4 128/128 SSE4.1 4x3])
Node numbers 1-99 of 99 (MPI)
Send SIGUSR1 to mpirun for status
[cruncher:54746] 98 more processes have sent help message help-mpi-btl-base.txt / btl:no-nics
[cruncher:54746] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages
^C^CAbort is in progress...hit ctrl-c again within 5 seconds to forcibly terminate
<SNAP>
bofh@...ncher:/opt/JohnTheRipper/run$ ls *rec|wc -l
99

bofh@...ncher:/opt/JohnTheRipper/run$ rm *rec; mpirun -np 120 ./john --format=raw-md4 /tmp/hashes

Same outcome using --fork.

I'll check cluster specific settings and behavior. If you've got suggestions, please let me know.

Thanks,

Jeroen
