Update Tue Feb 10th 11:30am -- This issue is resolved.  

There is a bug in the changes we made to a part of our batch software during the downtime. The bug is affecting some users when they submit jobs to our system.

Classroom Project Resource Guide

Welcome to OSC! This document includes some useful information to help your classroom use of our resources be effective.

Access: We suggest that students consider connecting to https://ondemand.osc.edu/ to access the HPC resources. All production supercomputing resources can be accessed via that website, without having to worry about client configuration.

Resources: We currently have two production clusters, Oakley and Glenn, with Nvidia GPUs available on both (but in larger quantities on Oakley). Recent usage patterns have shown that jobs on Glenn typically execute faster. However, both systems have "debug" queues during typical business hours that allow small jobs of less than 1 hour to start much quicker than they might otherwise.

If you need to reserve access to particular resources, please contact OSC Help (preferably with at least two weeks lead time) so that we can put in the required reservations to ensure resources are available during lab or class times.

Software: We have a list of supported software, including sample batch scripts, in our documentation. If you have specific needs that we can help with, let OSC Help know.

Students: We have a single-page guide for new students to help them figure out the basics of using OSC at http://www.osc.edu/new_user. Included are basics on getting connected, HPC system structure, file transfers, and batch systems.

Support: You can find events at the center (including training) by visiting osc.edu/e , system notices are at osc.edu/n , we provide important information in the “message of the day” (visible when you log in), and you can get notices by following @HPCNotices on Twitter. Help can be found by contacting OSC Help weekdays, 9AM to 5PM.
