About the RCF Computing Cluster
The RCF now hosts a Beowulf-style computing cluster, accessible to all members of the Department of Mathematics & Statistics. There is (and will forever remain) zero cost to using the cluster. Resources are currently allocated on a “first come, first serve” basis (although we expect this to change as demand increases). Right now, there are 752 cores distributed across 26 nodes, with an average of ~1 GB of memory per core, and we’re constantly in the process of adding more nodes as they become available.
Currently the cluster runs Centos 7, uses Slurm for workload management, and uses OpenMPI for message passing. The user home directories available on ssh are also mounted on the cluster. The development environment consists of the GNU autotools and compiler toolchain, python, R, Pari/GP, and many other common packages and libraries. If there is any additional software you would find useful for your research, please don’t hesitate to put in a request to rcfsupport@groups.umass.edu.
We will be adding to this documentation consistently as this project grows!

Scheduling Manager
The cluster uses a scheduling manager called “slurm” to allocate CPUs and memory. If you want to run a job on the cluster, you must submit it through slurm. Note users without a slurm account will NOT be able to submit jobs. To request an acount, please contact the RCF at rcfsupport@groups.umass.edu. Documentation for using slurm on our cluster can be found in the Submitting Jobs section. There are also many slurm tutorials available online. In particular, we recommend checking out the Slurm FAQ and this Quick Start Guide.
