Pitzer OS Upgrade and Early User Program

During the early access period, the programming environment and software packages will keep being updated; and the system may go down or jobs may be killed with little or no warning. If your work won't tolerate this level of instability, we recommend that you use other clusters instead.
This page is still under development, and information will be updated periodically.
