- No access to virtual machines or services running on virtual machines
- No access to CHPC file systems - (i.e. mounts to your desktop)
- No access to HPC Clusters - The clusters will stay up and scheduling jobs
RESOLVED: July 27, 2015
We have had reports of transient issues with users trying to connect to CHPC file systems from their windows and mac desktops. We are working to troubleshoot the issue and will send another note when we either have resolved the issue or know more about the extent and the time to resolve.
Files in /scratch will now be scrubbed based on atime (last accessed) rather than mtime (last modified)

Imaging Magma Reservoir beneath Yellowstone Park
The supervolcano that lies beneath Yellowstone National Park is one of the world’s largest active volcanoes. University of Utah seismologists Fan-Chi Lin, Hsin-Hua Huang, Robert B. Smith and Jamie Farrell have used advanced seismic imaging techniques to develop a more complete view of the magma chamber beneath this supervolcano, extending the known range from 12 miles underground to 28 miles. For the study the researchers used new methods to combine the seismic information from two sources. Data from local quakes and shallower crust were provided by University of Utah Seismographic Stations surrounding Yellowstone. Information on the deeper structures was provided by the NSF-funded EarthScope array of seismometers across the US.
Their recent study, as reported in the May 15, 2015 issue of Science, reveals that along with the previously known upper magma chamber there is also a second previously unknown second reservoir that is deeper and nearly 5 times larger than the upper chamber, as depicted in the cross-section illustration which cuts from the southwest to the northeast under Yellowstone. This study provides the first complete view of the plumbing system that supplies hot and partly molten rock from the Yellowstone hotspot to the Yellowstone supervolcano. Together these chambers have enough magma to fill the Grand Canyon nearly 14 times. Using resources at the Center for High Performance Computing, new 3D models are being developed to provide greater insight into the potential seismic and volcanic hazards presented by this supervolcano.
