- Subject: [Condor-users] out-of-memory issues in parallel universe
We have some macih es with 4 Gb RAM, and some with 6 Gb RAM all in the
same cluster, and may be seeing some over-extension of memory for MPI
jobs that are asssuming that there's 6 Gb of RAM available.
Is there some way of specifying the image size, and restricting jobs
to larger memory compute nodes, for MPI jobs submitted in the parallel
Also, what's the recommended way to enforce memory constraints on
jobs, in general and in particular in the parallel universe? ulimit?
