Access Policy

Research Associates, Postdoctoral Researchers and Students

If you are classified as a Research Associate, Postdoctoral Researcher or Student, you need to get an account through a CWRU faculty. Please ask the faculty to add you once their HPC account is set up properly. The addition can be accomplished by using the online portal AMARA. Please note that only Faculty and the designated managers can access this website. A student does not have the permission to access the portal.

Checking Resources Available:

A quick way to check which your resources is to you use the "i" command, as it shows:

• Your accounts and the maximum processors at a time

• Your current jobs

• The jobs of your other group members

The command "quotagrp <account>" which breaks down the account group's /home usage can be useful.

Detailed Member Access vs. Guest Access

Member Access 

• Each job submitted by a Member may not exceed 320 hours of walltime.

• There is currently a limit of 2000 jobs in the queue for the research group

• The number of jobs that a research group runs at a time will be determined by the Member/Guest level

• There is max limit of 6 (GPU cards) x n (unit of membership) GPU resources. As an example, for 2-unit membership, up to 6 x 2 (=12) GPU cards can be used at a time.

• The group will be provided a soft and hard disk quota of 700 and 920GB respectively in their collective /home directories. This quota cannot be expanded since the space is backed up with a month-long snapshot and multiple replication. You can get more storage space on the HPC storage or Research Storage by contacting us.  Please also check HPC storage for more information.

On occasion a member may reserve all (or a portion) of the processors representing his/her membership share for exclusive use. This reservation must be made far enough in advance (up to two weeks) in order that jobs already running do not interfere with the reservation. When a member has an exclusive reservation in effect, any processors used by that member’s jobs in excess of his/her membership share will run with guest priorities in effect. The use of these exclusive reservations will be reviewed periodically by the faculty governance body. As membership in the HPC Resource provides significant benefits associated with the sharing of resources, requests for permanent exclusive use will not be allowed.

Member jobs are given higher priority ahead of Guest jobs.

Guest Access

• Each job submitted by a guest may not exceed 36 hours of walltime.

• The total number of processors in simultaneous use by jobs within a Guest group is limited to 24.

• The total number of jobs permitted to run simultaneously within a Guest group is limited to 12.

• Guest has a maximum usage of 1 GPU card at a time.

• Each Guest group will be provided a soft and hard disk quota of 150 and 260GB in the collective /home directories of the group.
