The next NHUG meeting is scheduled for Tuesday, May 20th, 2025, at 1 PM MT, and we invite all NCAR HPC users to attend. This month’s agenda will include: • Upcoming opportunities and upcoming extended outage • Casper System Changes: DNS transition & swap space deactivation for HTC jobs • Asynchronous I/O and optimized data compression workflow for running weather models – Haying Xu To add this...
As previously announced, CISL staff will be performing necessary facility maintenance at the NCAR-Wyoming Supercomputing Center (NWSC) beginning on June 2 to replace critical power and cooling systems which have reached their end service life. Because of the nature of this work, it will be necessary to shut down all Derecho compute nodes, the Quasar tape archive, and a portion of the Casper com...
On Wednesday, May 28, from 2:00 pm to 3:00 pm MT, NSF NCAR’s High Altitude Observatory (HAO) will host a seminar entitled "Ionospheric Sensing Using High-Rate GNSS Reflectometry and Occultation Measurements from Low Earth Orbit." The speaker will be Dr. Yang Wang, a visiting faculty member in the Ann and H. J. Smead Aerospace Engineering Sciences Department at the University of Colorado Boulder...
Two user-visible changes are planned for the Casper cluster in the coming month. The first change will be the removal of the deprecated casper.ucar.edu domain name for SSH login usage. The current recommended domain name for accessing Casper is casper.hpc.ucar.edu. The old address will be retired as early as May 21, so now is the time to switch to the casper.hpc.ucar.edu domain when using ssh/s...

Leveraging NSF NCAR supercomputing, Johns Hopkins researchers have crafted a simple yet powerful formula modeling lower atmospheric winds. This innovative work, which utilized the Cheyenne supercomputer, condenses complex data into a user-friendly model of wind velocity at various heights. This work offers significant benefits for climate science and renewable energy. In a new CISL News articl...
