OSC offers the use of budgets to limit the amount of charges incurred on projects.
Active budget
Once a budget has been approved, it (and the project it was requested from) becomes active. Having an active project allows users on that project to submit batch jobs to use OSC resources.
It is useful to take a look at usage over periods of time and calculate overall usage at osc. This page explains how to do this using the HPC Job Activity tool in my.osc.edu
After logging into the client portal, navigate to Individual -> HPC Job Activity.
Enter the appropriate dates:
There are different requirements for being able to charge OSC usage towards a grant. This page aims to provide general guidelines, but actual requirements may be different. Contact OSC help if there are specific questions/needs.

OSC will be refreshing the software stack for Owens and Pitzer on May 19, 2020. This will be done in a system-wide downtime. During the software refresh, some default versions will be changed to be more up-to-date. Information about the new default versions, as well as all available versions of each software package will be included on the corresponding OSC software webpage.

This document shows you how to use the POSIX ACL permissions system. An ACL (access control list) is a list of permissions associated with a file or directory. These permissions allow you to restrict access to a certian file or directory by user or group.
These commands are useful for project and scratch dirs located in /fs/ess.
Understanding POSIX ACL
An example of a basic POSIX ACL would look like this:
