HPC Resource Disruption & Resolution from Saturday, April 12

April 14, 2025

Derecho compute nodes went down Saturday, April 12, due to an issue with servicing and distributing their filesystem data. Systems engineers quickly triaged the issue and returned Derecho to service several hours later. All jobs running on Derecho at the time - approximately 10AM MDT - failed. The disruption temporarily interrupted file system activities, which also caused running Casper job...

Read the article, “Simulated forests, real trees: mapping modeled data onto a living, breathing ecosystem”

April 7, 2025

A recent study tapped into the power of CISL supercomputers Cheyenne and Derecho to create virtual forests and provide valuable insights into the inner workings of these vital ecosystems. By employing advanced numerical simulations, researchers effectively separated the contributions of plants from those of the soil, a challenging task in real-world measurements. The team pioneered a methodol...
