SEAS Compute Resources

The Harvard John A. Paulson School of Engineering and Applied Sciences has a number of compute resources managed by FAS Research Computing. Members of the SEAS community may access compute resources using this information. Available partitions and their component parts:

Partition Name	Assigned Compute Nodes	Description of nodes

The partitions and the groups that have access to them are listed here. For restricted slurm compute partitions you will need to be in the proper AD group to submit jobs (type “id” on the command line to see the groups you are in). These groups have priority access to the listed resources; they are part of the general pool when not in use. Nearly all compute nodes are part of the “serial_requeue” or “gpu_requeue”. This is the backfill scheduler – any higher priority jobs will kick those off of the node if the resources are needed. Lowest priority and shortest running jobs are preempted first.

Partition Name	Group(s) Who Have Access	Additional notes
seas_gpu	seas
seas_dgx1	seas
seas_dgx1_priority	acc_lab rush_lab kung_lab
seas_gpu_requeue	seas
seas_iacs	seas_iacs
narang_dgx1	narang_lab

tambe_gpu	tambe_lab
barak_ysinger_gpu	barak_lab ysinger_group
idreos_parkes	idreos_lab parkes_lab
seas	slurm_group_seas	Is requeued by higher priority jobs in seas_priority
seas_priority	slurm_group_seas	Only groups with a higher fairshare than 0.75 may submit to this partition

Adding additional lab groups or cluster access

GROUP MEMBERSHIP

If you already have a FAS RC account (Note: multiple accounts are not allowed) and need to request membership in an additional lab group, the following will explain how to do so.

Your account can belong to multiple groups, with your PI/sponsor’s lab group being your primary. If you need to submit jobs under different labs groups you belong to, see: How do I fairly manage dual/multiple lab affiliations for work on the FASRC cluster?

CHANGING LABS

If you need to change your primary PI/sponsor to another lab group, please see How do I change lab groups?.

ADDING GROUPS

Requesting additional groups for file access can be done via our Portal.

Log into the Portal and select ‘Cluster Access’ on the left (or click here: https://portal.rc.fas.harvard.edu/request/ )
Two new links should appear on the left
– My Grants – Shows you all your current grants/memberships
– Add Grants – Lets you request new grants/memberships
Find the grant you wish to add and select its check box. A window will pop up allowing you to Cancel or Request Selected.

After clicking Request Selected, an approval message will be sent to the group’s approver (usually the PI, their lab manager, admin, etc.)

Once they approve your request, you will receive a notification via email.

You can check the status of your request or the groups you currently have by clicking on the My Grants link at any time.

NOTE: If you will need to be able to run jobs under that secondary group’s fairshare, please send FASRC a ticket (via Portal or Email) asking to be added to the lab’s SLURM group. See managing dual/multiple lab affiliations for details on using switching fairshare affiliations on jobs.

ADDING CLUSTER ACCESS

If you did not initially request cluster login access, you can also use the procedure above to request Cluster Access. This will allow you to log into the cluster and submit jobs. Go to Add Grants, Click ‘Cluster’ (if it does not appear, then you already have cluster access) to select the ‘FASRC cluster access’ checkbox.

If you are trying to SSH into the cluster and are constantly asked for your password or get an error about your home directory, this is the cause.
