The GLADE file systems and Yellowstone, Geyser, and Caldera clusters will be unavailable from 6:30 a.m. to 6 p.m. Tuesday, June 28, as we prepare to provide larger home file spaces for Yellowstone users and ramp up GLADE capacity for installation and testing of the new Cheyenne system.

Changes being implemented in early August will include a significant increase from the current 10-GB user home space. The new quota will be announced before the increase, along with some adjustments to backup and snapshot policies.

A system reservation will be put in place 12 hours before Tuesday’s scheduled downtime. Users’ jobs with specified job times that overlap the reservation period will remain on hold until the system is restored to service. Longer-running jobs that have not finished by 6:30 a.m. Tuesday will be killed and will need to be resubmitted after the maintenance period. We apologize for any inconvenience this might cause.

Early-career atmospheric scientists and graduate students at U.S. universities and non-profit research institutions are eligible to attend the CMIP Analysis Platform Tutorial workshop, which is scheduled for August 16-18, 2016, at the NCAR Mesa Lab in Boulder.

The workshop, funded by the National Science Foundation, will include lectures as well as hands-on, practical sessions. In addition to presentations on using the CMIP Analysis Platform, topics will center around statistical methods for analyzing climate model output with a special focus on multi-model ensemble analysis. 

See the tutorial web page for details and an application form.

The CISL User Services Section is preparing a summary report on results of the Cheyenne User Environment Survey. In the meantime, we will share some individual comments and responses that may be of interest to both Yellowstone and Cheyenne users.

User comment: It would be good to have some type of indication of how many users are currently using a particular queue.

CISL says: This information is readily available on the CISL Resource Status page for Yellowstone and we anticipate having a similar report for Cheyenne. When you are logged in to Yellowstone, you can get similar information by running the bsumm command.

User comment: It would be perfect if GLADE can be accessed from both Cheyenne and Yellowstone, if NCAR will operate both machines.

CISL says: You will be able to access GLADE from both Cheyenne and Yellowstone. The plan is to have both systems in production for about a year before Yellowstone is decommissioned.

Presentations introducing the new 5.34-petaflops Cheyenne HPC system are scheduled for July 1 at the Foothills Lab and July 8 at Center Green. Dave Hart, CISL’s User Services Section manager, will discuss the capabilities of the new system, which will be installed at the NCAR-Wyoming Supercomputing Center in the second half of 2016. It is scheduled to become operational at the beginning of 2017.

The presentations are scheduled as follows:

  • Foothills Lab (FL2-1001) - 11 a.m. Friday, July 1

  • Center Green (CG1-2126) - 11 a.m. Friday, July 8

A webcast also is being planned in August for university users and others who can’t attend in person. Details will be announced later.
