The Lawrence high-memory (himem) node has two partitions, each with 1.5 TB of RAM. This node is especially useful for jobs requiring a large amount of memory and can be accessed either interactively or with a batch script.
For interactive jobs on the Lawrence himem nodes, use the srun command as follows:
[user.name@usd.local@login ~]$ srun --pty -p himem bash
[user.name@usd.local@himem02 ~]$
To use the high memory node within a batch job, add “--partition=himem” to your script.
Below is an example batch script which calls the a high-memory node. This template can be followed when requesting the himem node on Lawrence:
#!/bin/bash
# Example job submission script
# This is a comment.
# Lines beginning with the # symbol are comments and are not interpreted by
# the Job Scheduler.
# Lines beginning with #SBATCH are special commands to configure the job.
