Subject: OpenMPI and .rec files?


If I run john with --fork on a N core machine, I'll see N .rec files for
resuming the task. So I guess it's one .rec file per process.

I'm now playing with a OpenMPI environment, using e.g. 20 systems with 32
processes each. When john starts, 640 processes phone home

502 0g 0:00:00:00 ..
614 0g 0:00:00:00 ..
640 0g 0:00:00:00 ..

In total 100 .rec files are generated, where I would expect 640 or perhaps

Same result for OpenMPI tasks with (more OR less than 640) AND more than 100

Is all the resume data in 100 recovery files, don't matter the number of
tasks or is there something going wrong?
