Training Sessions

ARCH will be providing the following training sessions:

  1. Introduction to Linux: Hands on session for users with no or little knowledge of Command Line Interface (CLI) in Linux.Date: Monday April 17, 2-4 PMLocation: Bloomberg (P&A) 46

Rockfish Maintenance:

All Rockfish Systems will be unavailable from April 24th at 12:01AM to April 30th at 12:01AM. Contractors will be performing facility wide maintenance beginning on April 24th. We strongly recommend users to copy any data that may be needed during this downtime to an external device as access to Rockfish storage will not be available. Click here for more details. 


For all users of MATLAB, we ask that you please add ‘exit’ at the end of your MATLAB scripts. Our system uses a license manager where a certain number of MATLAB license can be checked-out that need to be checked-in after job execution. Without ‘exit’, licenses are not returned and, once licenses run out, users cannot use MATLAB. Please ensure you are exiting correctly for the smooth operation of Rockfish and for the research community.

Job Opportunity:

Are you interested in joining the HPC workforce? As a Research Computing and Data Specialist (RCD) or Research Software Engineer (RSE) you will have plenty of opportunities to participate in innovative projects, establish collaborations with different research groups, support and enable cutting-edge research. ARCH has several opening at the assistant research scientist level. For more information:

Script Updates: "user-sbalance" and "":

We have added two scripts called “user-sbalance” and “”.

“user-sbalance” reports user and group utilization for the current quarter. “” provides utilization and quotas as well as number of files a group has in Rockfish file-systems. For examples of how these scripts work, visit our FAQ page here. 

Research Profile: Lan Cheng
