All jobs on the general purpose cluster request resources via SLURM. SLURM, is open source software that allocates resources to users for their computations, provides a framework for starting, executing and monitoring compute jobs, and arbitrates contention for resources by managing a queue of pending work. SLURM is widely used in the high performance computing (HPC) landscape and it is likely you will encounter it outside of our systems.

Resource information
All users have access to the "batch" partition for general purpose computing.
| Info |
|---|
| The batch partition is comprised of 544 CPUs and 21 compute nodes. Note that a job can only request 3 nodes and may only be active for 14 days. If you need an exception to this, please contact arcc@albany.edu. |

This job ran on rhea-09, and it's max memory size was ~52 GB. That that I requested 60000MB, so I could refine this job to request slightly less memory. It ran for 14:50:14 and used about 350 CPU hours. |
Can I restrict my job to a certain CPU architecture?
Yes! Use the --constraint flag in #SBATCH. To few available architecture on individual nodes use scontrol show node
