If anyone else is using xgrid, there is a mechanism to limit the

only send 8 processes to that node. For now tha
Looking at the code, you are correct in that the Xgrid launcher is
ignoring hostfiles. I'll have to look at it to determine how to
correct that situation - I didn't write that code, nor do I have a way
to test any changes I might make to it.
For now, though, if you add --bynode to your comm
Hi Vitorio,
Thanks for getting back to me! My hostfile is

Hi,
So you have 4 nodes each one with 2 processors, each processor 4-core
- quad-core.
So you have capacity for 32 process in parallel.
I think that only using the hostfile is enough is how I use. If you to
specify a specific host or a different sequence, the mpirun will obey

Hi all,
Sorry in advance if these are naive questions - I'm not experienced in
running a grid...
I'm using openMPI on 4 duo Quad-core Xeon xserves. The 8 cores mimic
16 cores and show up in xgrid as each agent having 16 processors.
However, the processing speed goes down as the used pr
