Re: [BProc] Clustermatic 5 Queueing system

[Daniel G. <dg...@cp...>]

Hi Patrice,

I use bjs, which is the batch scheduler that comes with cm5.  I use
version 1.6.  It is pretty simple minded, but it works quite well.
The only issue with it - and it may not be an issue for you at all -
is that the batch system gives you nodes, rather than processors.
In other words, if your nodes are dual-cpu you need to run 2 processes
on the node in order to take advantage of the machine.  We do this for
serial jobs by submitting 2 processes in the script that the user
submits to bjs.  For mpi codes this is not a problem at all - you
simply tell mpirun to pack the processes on the nodes (you need to use
the mpirun that is supplied with clustermatic, since it is the only
one that is bproc-aware).

It would be really nice if someone went through the trouble of porting
SGE or OpenPBS or something else to bproc, but in the meantime bjs 
does the job.

Regards,
Daniel
