Daily Bulletin Archive

January 21, 2020

Users are reminded that the High Performance Storage System (HPSS) tape archive will become read-only on Monday, January 20. The only exceptions will be for curated collections such as the Research Data Archive. This follows the October 2019 announcement that HPSS will reach its end of life and be decommissioned in 2021.

While writing HPSS files will not be possible as of January 20, users will still be able to perform most common meta-data operations on their HPSS holdings, including deleting, renaming, and moving files. Those who have not already done so should begin deleting files that are no longer needed and moving other data to alternative storage systems.

CISL recently published documentation and training for users on recommended processes for identifying and organizing HPSS holdings; copying files that need to be preserved to another storage resource; and deleting files that are no longer needed. Follow these links:

Additional CISL Daily Bulletin announcements will follow as new tools, training, and expanded documentation become available to support the data migration. In the meantime, please contact CISL for advice on individual workflows and storage options.

The CISL Consulting Services Group is responding to help tickets but consultants are not available for walk-ins today through January 20 because of the Mesa Lab recabling project. To arrange for in-person consulting assistance, please submit a ticket through the NCAR Research Computing portal or call 303-497-2400.

This does not affect Help Desk services in ML-31. Staff who need assistance can stop in there, call the phone number above, or use the Staff Support portal to request help.

The Cheyenne cluster will be unavailable to users in late February to allow CISL staff and HPE engineers to perform critical infrastructure maintenance, repairs, and system software updates. The maintenance period will begin Tuesday, February 25, and the system is expected to be returned to service no later than Saturday, February 29.

The Casper cluster, GLADE file systems, Campaign Storage, data-access nodes, and HPSS will remain available throughout the week. Watch for more details and updates in upcoming Daily Bulletins.

The Artificial Intelligence for Earth System Science (AI4ESS) Summer School is accepting applications until January 31. The event will take place the week of June 22-26, 2020, at NCAR's Mesa Laboratory in Boulder.

Who should apply

Graduate students, postdocs, faculty, research scientists, software engineers, and data scientists focused on Earth system science are encouraged to apply. Previous machine learning experience is not required. Some experience with Python and scientific Python libraries will be needed to contribute to the breakout sessions.

Application process

We have room for up to 80 participants but are expecting interest to exceed capacity. In order to ensure that the applicants who could most benefit can attend, we have a formal application and review process for the summer school. To apply, please fill out the application form. Applications are due by Friday, January 31, at 5 p.m. MST. Acceptance notifications will be sent out in early March, and those selected will be invited to register. A waiting list will also be created in the event that some participants are not able to attend.

Individuals who use the ExtraView help ticketing system are now required to log in with a CIT (Active Directory) password rather than their UCAS (Kerberos) password. The change, which was announced recently in Notifier emails to users, took effect this morning.

Most CISL help desk support is now provided via the Staff Support and NCAR Research Computing support portals rather than ExtraView, which NETS, Infrastructure, and Asset Managers still use.

The Casper node upgrades described in this previous article have all been completed. New hardware required updates to network software on all Casper nodes. The updates required Open MPI 3.1.4 to be rebuilt and it is likely that older versions of OpenMPI will no longer work. CISL will test existing Open MPI modules in the coming weeks and remove any versions that no longer function correctly.
