this is about Torque and MPICH2.
I am writing a pbs job description that
starts MPI jobs on a number of machines.
The pbs script specifies 4 nodes with
4 processors each and generates a
PBS_NODEFILE that looks like this
However, the mpiexec needs a file like this
So I wrote a little script that does this.
So far so good. When the mpdboot starts,
it ignores one of the nodes and uses the
masternode instead and refuses to start
more than 13 processes.
There must be someone that has solved this. :)
