HPC systems maintenance activities continue. Cheyenne and GLADE were returned to service Tuesday evening and continue to perform well. Maintenance is ongoing for Derecho, Casper, and JupyterHub. Casper operating system updates are largely complete, with CISL engineers finalizing evaluation of all Casper services. JupyterHub remains under maintenance along with Casper, and we currently plan ...
ASWIG (Analysis Workflow Special Interest Group) will host a lightly-moderated discussion about the challenges of using Dask in workflows on Monday, October 30th, from 2-3pm. We invite those who have integrated Dask into their projects to share strategies, approaches, and insights from their experiences. For users who faced challenges in adopting Dask, we'd like to hear about the specific chall...
Join us Nov. 2, 2023, 11 am – 12:30 pm Mountain Time, for a seminar from Henry Santer, a visiting graduate student from the University of Maryland. His research focuses on the development of novel methods for estimating and visualizing uncertainty in geophysical modeling systems. In this seminar, he will demonstrate the potential value of contour band depth for analyzing ensemble data with a c...
HPC systems maintenance activities continue and are proceeding well. GLADE file space transitions and storage maintenance activities have been completed. Cheyenne has been returned to service. Jobs that were held in the queues at the beginning of the maintenance period are now running again. (Cheyenne will not be accessible through JupyterHub until later in the outage, when broader Jupyter...
Cheyenne is being retired on December 31, 2023. As of this week, only two months remain to switch all projects from Cheyenne to Derecho. Make it a priority to transition your computing projects to Derecho as soon as possible, to avoid needing to repeat important runs. CISL cannot provide anyone with special priority to complete last-minute work, so consider it imperative to switch at the next ...
Researchers can now access CONUS404, a remarkable new dataset on U.S. weather patterns, through the Casper analysis cluster. The nearly one-petabyte dataset is the result of a collaboration between the National Center for Atmospheric Research (NCAR) and the U.S. Geological Survey (USGS) and was recently published in NCAR’s Research Data Archive (RDA). The CONUS404 dataset covers the contiguo...
