GLADE project space user quotas will be reset at noon MDT on Friday, April 28, to prevent the /glade/p space from hitting the 95% full mark again as it did earlier this week. If the file system reaches 95% full and a downtime and remount of the file system become necessary, some data may be lost.

To help ensure the file system’s stability and continued availability, users’ project space quotas will be set to  a level that accommodates their file holdings as of the morning of Wednesday, April 26. Jobs that run after the new quotas are established will fail if output is directed to project space that is at capacity.

Project space users are advised to immediately review their workflows so that job output is written to the recently expanded /glade/scratch file space rather than /glade/p. CISL also again advises users to delete files from project space that are no longer needed. The new quotas will remain in effect until early June when /glade/p is expanded with the old GLADE scratch disk.

Project space is not intended for use as a long-term data repository. Users who need to remove thousands or hundreds of thousands of files from a GLADE directory should review Removing large numbers of files for how to do that most efficiently.

CISL will resume enforcing the 45-day /glade/scratch purge policy on June 1. The policy was suspended during the recent transition to the new, larger GLADE scratch system. Users’ files that are not accessed (for example: modified, read, or copied) within the 45 days following June 1 will be deleted automatically on July 15.

Also on June 1, as announced previously, the read-only /glade/scratch_old file space will be removed so it can be repurposed. Yellowstone users who have not already done so should move any scratch files that they want to keep from /glade/scratch_old to /glade/scratch before that date.

Please see GLADE File Spaces for more information about using the GLADE centralized file service.

An important deadline is coming Monday, May 1, for anyone interested in submitting poster abstracts, Visualization Showcase proposals or Birds-of-a-Feather proposals for PEARC 17—the Practice and Experience in Advanced Research Computing conference in New Orleans, July 9-13, 2017.

Submissions should emphasize experiences and lessons derived from operation and use of advanced research computing on campuses or provided for the academic and open science communities. Submissions that align with the conference theme—Sustainability, Success, and Impact—are particularly encouraged. See the Call for Participation for more information.

Students whose posters are accepted are eligible to apply for financial support to cover the costs of airfare, shared lodging, and registration fees.

A number of users have contacted the CISL Help Desk to ask about how to change their default login shell. The quickest way to do that—for both Cheyenne and Yellowstone—is through our Systems Accounting Manager (SAM). In the “Login Shell” section of your preferences screen, select a system and then click the “Edit” button to make your change. It may take several hours for the change to take effect.

What else can you do with SAM? See this page to find out.
