- Subject: [condor-users] synchronously starting multiple jobs in Condor
My group has developed a Matlab library, called MatlabMPI, which
implements a subset of the MPI library. Currently, it launches Matlab
on multiple machines by sending commands via rsh. Currently, we are
trying to integrate MatlabMPI with Condor.
Like MPI, all processes in a MatlabMPI program must start executing at
the same time. Otherwise, any process that needs to communicate with an
idle process will cause the MatlabMPI program to hang.
We have been trying to figure out if there is a way to force Condor to
synchronously start executing a set of Matlab processes distributed
across a cluster. Does any one have any ideas? Is this functionality
built into Condor, or will this require a hack?
