The Rocky Mountain Advanced Computing Consortium’s 7th annual High Performance Computing (HPC) Symposium, August 15-17 in Boulder, will feature an innovative “Keynote Debate” on the future of HPC architecture. In another keynote, New York filmmaker, composer and director Kenji Williams will speak about his NASA-powered data visualization spectacle, the film “BELLA GAIA.”

Keynote debate participants will be Marc Hamilton, Vice President of Solutions Architecture and Engineering at NVIDIA; Mike Vildibill, Vice President of Exascale Development Programs at Hewlett Packard Enterprise; Jerry Lotto, Director HPC and Technical Computing at Mellanox; and William Magro, Chief Technologist for HPC Software at Intel. Dr. Thomas Hauser, Director of Research Computing at CU-Boulder and RMACC Chair, will act as debate leader, and Tiffany Trader, Managing Editor of HPCwire, will moderate the debate.

The symposium’s technical program features six concurrent tracks covering a wide range of advanced computing topics, with a particular emphasis on data analytics and visualization. See the RMACC site for more information and to register to attend.

The Cheyenne cluster and GLADE project space — /glade/p — will be unavailable from 8 a.m. until 10 a.m. MDT on Tuesday, August 8,  to allow CISL staff to perform important system maintenance. Also, users will be logged off and locked out of the Cheyenne login nodes during the maintenance window. Yellowstone, Geyser, and Caldera users may experience interruptions or errors accessing /glade/p files  during this maintenance.

A system reservation will be put in place on batch jobs Monday afternoon on Cheyenne. Jobs submitted with specified job times that overlap the reservation period will remain on hold until the system is restored to service. Running jobs that have not finished when the outage begins may be killed and need to be resubmitted after the system is restored to service. Users are advised to take this into account before submitting long jobs after 8 p.m. on Monday.  

We apologize for any inconvenience this might cause. Users will be informed via the CISL Notifier service when the system is returned to production.

The Cheyenne cluster will be unavailable from 8 a.m. MDT on Saturday, July 29, until 5 p.m. Sunday, July 30, to allow CISL staff to perform important system tests.

A system reservation will be put in place on batch jobs Friday afternoon. Jobs submitted with specified job times that overlap the reservation period will remain on hold until the system is restored to service.

We apologize for any inconvenience this might cause. Users will be informed via the CISL Notifier service when the system is returned to production.

Cheyenne users can now run a “qpeek” script to check on the progress of their running jobs. The script inspects a specified job’s stdout log by default. Documentation added to Managing and monitoring jobs describes how to check stderr instead, and how to merge stdout and stderr in a job script so that qpeek can check both while the job is running.

No Downtime: Yellowstone, Cheyenne, HPSS, Geyser_Caldera, GLADE

Jul. 20, 2017

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.

CISL resumed 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, the temporary,  read-only /glade/scratch_old file space was removed and will be repurposed. Please see GLADE File Spaces for more information about using the GLADE centralized file service.

Registration is now open for this summer’s free ACI-REF Virtual Residency Workshop on “How to Be a More Effective Research Computing Facilitator.” Participants can attend remotely via videoconference or in person at the University of Oklahoma from Sunday, July 30, to Saturday, August 5.

The workshop is intended for those who want to be more effective at helping researchers and educators use research cyberinfrastructure. Participants are expected to give a five-minute presentation on a project that they intend to carry out at their home institution after the workshop ends. They also are asked to participate in a second summer workshop and in Virtual Residency conference calls during the next two academic years. See the application form for more information.
