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:

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.

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.

CISL staff will update several key data analysis and visualization system components and the Campaign Storage file system beginning at 8 a.m. MST. The maintenance will affect the availability of the Casper, Geyser, and Caldera clusters and file transfers to Campaign Storage. The GLADE file system is expected to remain available throughout the day.

Maintenance on Casper, Geyser, and Caldera is expected to take until 12 noon MST. 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.

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

Users who previously logged in to the Systems Accounting Manager (SAM) with a YubiKey token now need to log in with either a CIT password or Duo two-factor authentication. Any users who do not have a CIT password or Duo can request either by contacting the CISL Help Desk at 303-497-2400 or cislhelp@ucar.edu.

December 5, 2018

The CISL Help Desk and Consulting Office will be closed Wednesday 3:00 pm - 5:30 pm for a CISL function. For assistance with any urgent issues, call 303-497-2400 or email cislhelp@ucar.edu both of which are always monitored.

No downtime: Cheyenne, GLADE, Geyser_Caldera, HPSS and Casper

November 30, 2018

Users should migrate their data analysis and visualization (DAV) workflows to the new Casper cluster soon if they have not already done so. The Geyser and Caldera clusters will be decommissioned on December 31 and are experiencing more frequent hardware failures as they approach end of life. Several Geyser and Caldera nodes have already suffered irrecoverable hardware failures. They have been removed and will not be replaced.

During a scheduled maintenance downtime on December 11, the execdav command will be updated so it defaults to assigning Casper nodes for use in interactive jobs. When Geyser and Casper are decommissioned, the execgy and execca commands will be removed. Keep an eye out for more information about the December 11 downtime in upcoming Daily Bulletins.
