ClassAccounts

UMIACS Class Accounts are currently intended to support classes being sponsored by the Center for Machine Learning.

You will be notified by email that you have an account to redeem. If you have not received an email, please contact your TA. You must redeem the account within 7 days or else the redemption token will expire. If your redemption token does expire, please contact your TA to submit a request to staff to have it renewed.

Once you do perform the redemption of your account, you will need to wait until you get a confirmation email that your account has been installed. This is done in batch once a day on days that the University is open for business.

Once notified that your account has been installed, you can access the following class submission host(s) using SSH with your assigned username and the password you provided:

class.umiacs.umd.edu

Your home directory has a quota of 20GB and is located at:

/fs/classhomes/<semester><year>/<coursecode>/<username>

where <semester> is either "spring", "summer", "fall", or "winter", <year> is the current year e.g., "2021", <coursecode> is the class' course code as listed in UMD's Schedule of Classes in all lowercase e.g., "cmsc999z", and <username> is the username mentioned in the email you received to redeem the account, e.g. "c999z000".

You can request up to another 100GB of storage if you would like by contacting staff. This storage will be located at

/fs/class-projects/<semester><year>/<coursecode>/<username>

You may not run computational jobs on the submission host. You must schedule your jobs with the SLURM workload manager. You can also find out more with the public documentation for the SLURM Workload Manager.

Class accounts only have access to the following submission parameters in SLURM. You may be required to explicitly set each of these in your submission parameters.

• Partition - class
• Account - class
• QoS - default

Any questions or issues with the cluster must be first made through your TA.
