Re: [Condor-users] MPICH2 wrapper script (mpich2script) for parallel universe

[Mark Calleja <M.Calleja@xxxxxxxxxxxxxxx>]

Hi Senthil,

I'm afraid I didn't come across this error, so I can't reproduce it to 
debug it. Just a few more notes about my setup, in case you can spot any 
important differences with what you have. I run Condor as root, and each 
VM on a machine has its own dedicated user with the same .mpd.conf file. 
Apart from that I followed the 6.8.4 manual recipe for parallel universe 
operation.

What happens if you submit a single node mpi job?

Regards,
Mark
