None planned for Cheyenne, Casper, GLADE, Campaign Storage, Quasar, Stratus, or JupyterHub.
The Cheyenne Infiniband high-speed network has suffered two failed switches as a result of cooling system problems that will require a system outage in order for the vendor to repair and replace. The dates for this outage are currently being planned. We expect the outage will require 3-5 days effort and will occur no earlier than 3 weeks from now. If users have any flexibility to defer runnin...
Derecho’s Acceptance Test Phase (ATP) continued last week and the project reached a milestone when Accelerated Scientific Discovery (ASD) users were given access to the system on June 1 to begin building and running their models. While the vast majority of the benchmark results meet or exceed expectations, and the cumulative performance is meeting the required 3.5 CSEP metric, CISL continues to...
Abstracts are being accepted now through August 1 for the Workshop on Correctness and Reproducibility for Climate and Weather Software. This workshop will take place November 9 & 10 NCAR’s Mesa Laboratory in Boulder, Colorado, and virtually. We are soliciting talks related, but not limited to, the following topics: • Tools and approaches for software testing, debugging, quality assurance, and ...
Derecho’s Acceptance Test Phase (ATP) was resumed after CISL and HPE engineers significantly reduced job performance variability through some tuning and configuration changes. Additionally, HPE and CISL have been able to maintain an availability of 98% for the compute resources during this testing phase. While the vast majority of the benchmark results meet or exceed expectations, CISL is worki...
