Grace

Grace

Grace is a shared-use resource for the Faculty of Arts and Sciences (FAS). It consists of a variety of compute nodes networked over low-latency InfiniBand and mounts several shared filesystems.

The Grace cluster is is named for the computer scientist and United States Navy Rear Admiral Grace Murray Hopper, who received her Ph.D. in Mathematics from Yale in 1934.


System Status and Monitoring

For system status messages and the schedule for upcoming maintenance, please see the system status page. For a current node-level view of job activity, see the cluster monitor page (VPN only).

Partitions and Hardware

Grace is made up of several kinds of compute nodes. We group them into (sometimes overlapping) Slurm partitions meant to serve different purposes. By combining the --partition and --constraint Slurm options you can more finely control what nodes your jobs can run on.

Job Submission Rate Limits

Job submissions are limited to 200 jobs per hour. See the Rate Limits section in the Common Job Failures page for more info.

Public Partitions

See each tab below for more information about the available common use partitions.

Use the day partition for most batch jobs. This is the default if you don't specify one with --partition.

Private Partitions

With few exceptions, jobs submitted to private partitions are not considered when calculating your group's Fairshare. Your group can purchase additional hardware for private use, which we will make available as a pi_groupname partition. These nodes are purchased by you, but supported and administered by us. After vendor support expires, we retire compute nodes. Compute nodes can range from $10K to upwards of $50K depending on your requirements. If you are interested in purchasing nodes for your group, please contact us.

Storage

Grace has access to a number of filesystems. /gpfs/loomis is Grace's primary filesystem where home, project, and scratch60 directories are located. For more details on the different storage spaces, see our Cluster Storage documentation.

You can check your current storage usage & limits by running the getquota command. Your ~/project and ~/scratch60 directories are shortcuts. Get a list of the absolute paths to your directories with the mydirectories command. If you want to share data in your Project or Scratch directory, see the permissions page.

Warning

Files stored in scratch60 are purged if they are older than 60 days. You will receive an email alert one week before they are deleted.
