Computational Research Center
The University of North Dakota (UND) Computational Research Center (CRC) is dedicated to helping researchers affiliated with the University of North Dakota solve increasingly challenging problems in science and society.
By supporting high performance computing hardware, software and staff through the Division of Research, the University provides quality computing resources to its researchers and faculty involved in creative activities which require intricate numerical modeling and data-intensive simulations.
Routine maintenance is scheduled for the second Thursday of every month.
Scheduled Network Upgrades
All UND CRC services will be down finals week for network upgrades. The outage for network upgrades and maintenance is scheduled for December 13-17, 2021.
We have discovered a problem with old PuTTY versions causing login issues and/or performance degradation. Please ensure that your PuTTY version is up-to-date. The current PuTTY version is 0.76.
New Globus Server Available
The new Globus server has been deployed! Please see the new Globus instructions on the Tutorials page under Getting Started > Globus.
You will log in to talon.und.edu for all job submissions. To submit jobs to other queues (talon is default), simply add the following line to your submission script:
queue_name will be the queue you want to use. If you don't specify a queue, it will default to talon which is the default queue. Below is the list of available queues:
talon - Talon CPU, this is the default queue
talon-gpu - Talon GPU deep learning nodes
talon-fat - Large memory
For scheduling fairness and backfill scheduling efficiency, all Talon and Hodor queues now have default and maximum wall times enforced. The default and maximum wall times can be found below. The maximum wall times can also be found by running sinfo. Maximum wall times are subject to maintenance windows. If the default 2-hour wall time is not enough, then you will need to set your wall time in your submission script. Application checkpointing is always strongly encouraged.
talon - Default run time, 2 hours. Maximum run time, 28 days.
talon-fat - Default run time, 2 hours. Maximum run time, unlimited.
talon-gpu - Default run time, 2 hours. Maximum run time, 28 days.
