GLADE users who have not already done so need to take appropriate action soon to copy any files they need from the /glade/p_old/ or /glade/p_old/work file spaces. As announced previously, they will be decommissioned December 31 and all files will be removed permanently.

Users who have files in those spaces that they need to retain should copy them to one of the new storage systems. See Transfers between GLADE file spaces for how best to do this.

Project spaces

CISL recommends moving active project data to /glade/p/<entity>/<project_code>where entity can be univ, uwyo, cesm, mmm, nsc, or other designated NCAR lab or special program. A one-year purge policy will be enforced on files in those new spaces, meaning files that are not accessed for more than one year will be deleted.

Project data that are not active but need to be preserved should be moved to the Campaign Storage archive. Users access and manage their Campaign Storage files with Globus services. A five-year purge policy will be enforced on Campaign Storage effective from the date files are created in that archive.

Work spaces

All users now have individual directories in /glade/work with 1-TB quotas. Files in those directories are not purged. Users should copy any files they need from their /glade/p_old/work/ directories to their new /glade/work directories before December 31.

CISL staff will update several key data analysis and visualization system components and the Campaign Storage file system today. The maintenance will affect the availability of the Casper, Geyser, and Caldera clusters and file transfers to Campaign Storage. Cheyenne and the GLADE file system will remain available throughout the day.

Maintenance on the Campaign Storage file system will begin at 9 a.m. MST and is expected to last until 5 p.m. MST. Globus transfers will be suspended for the duration of the maintenance but will resume when the work is completed.

Maintenance on Casper, Geyser, and Caldera will begin at 9:30 a.m. MST and is expected to take approximately three hours. The work will include installing a new version of the Slurm resource scheduler. These clusters will not be accessible during the maintenance window. Also note:

  • All running jobs, interactive processes, and login sessions will be terminated when maintenance begins.

  • Jobs that are queued for execution or in a hold state will remain in those states until Casper, Geyser, and Caldera are returned to service.

CISL system administrators were able to install a new version of PBS during an unscheduled Cheyenne outage on Tuesday, December 4, so no Cheyenne downtime is needed during the maintenance period scheduled for December 11. Other system maintenance remains scheduled for December 11 as follows.

Registration is now open for a one-hour tutorial for Cheyenne and Casper users on the workings of the GLADE file storage system, which received a number of significant updates over the past several months. The tutorial is scheduled for 10 a.m. MST on Thursday, January 17. The tutorial will review the purposes and use of the system’s multiple file spaces and describe some best practices. These topics will be covered in detail:

  • Differences between users’ GLADE files spaces (examples: home, scratch, work).

  • Intended workflows and anticipated uses.

  • Making transfers between file spaces.

  • How and when to use the separate Campaign Storage system.

Register to attend in person – in the Damon Conference Room at NCAR’s Mesa Lab in Boulder – or attend online by selecting one of these links:

Downtime Geyser_Caldera: Tuesday Decemeber 11, 9:30 am to noon.

Campaign Store systems will be offline from 0900-1700 on Tuesday for a system upgrade. 

Globus transfers will be paused during the outage and restored when maintenance is complete.

A video recording and text from the November 29 NCAR/CISL tutorial on using the Globus command line interface (CLI) are now available, along with new script examples, on the CISL web site. The CLI enables programmatic access to NCAR and external data endpoints, including the new NCAR Campaign Storage system.

See the Globus CLI tutorial page to review the presentation and other materials. Topics covered include:

  • Initiating, monitoring, and modifying transfers between endpoints

  • Incorporating CLI commands into data mover scripts

  • Best practices for creating Globus workflows at NCAR

  • Strategies for using Campaign Storage

NCAR labs’ storage managers and project leads at universities that have Campaign Storage allocations can provide information about use of those storage spaces. Users can also contact cislhelp@ucar.edu for assistance with new workflows and using Globus.
