CHPC - Research Computing Support for the University

In addition to deploying and operating high performance computational resources and providing advanced user support and training, CHPC serves as an expert team to broadly support the increasingly diverse research computing needs on campus. These needs include support for big data, big data movement, data analytics, security, virtual machines, Windows science application servers, protected environments for data mining and analysis of protected health information, and advanced networking.

CHPC Downtime: Thursday July 30th from 4 - 6 p.m

Network outage completed 7/30 6:27 p.m.
VM farm outage completed 7/30 10:13 p.m.


  • No network access to any CHPC resource
  • Network down in INSCC Building
  • Protected Environment VM farm will be down during this time window
  • 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

Issues with mounting CHPC file systems from Windows and Macs desktops

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.

Change in CHPC /scratch file system scrubbing policy

Files in /scratch will now be scrubbed based on atime (last accessed)  rather than mtime (last modified)

Computational Fluid Dynamic Simulation of a Novel Flash Ironmaking Technology

The U.S. steel industry needs a new technology that produces steel from iron ore with lower greenhouse gas emission and energy consumption. At the University of Utah, Prof. Hong Yong Sohn and his team have conceived of a drastically novel idea for an alternative method called the Flash Ironmaking Technology to replace the century-old blast furnace process.  This new technology eliminates the highly problematic cokemaking and pelletization/sintering steps from the current ironmaking processes by directly utilizing iron ore concentrates, which are in abundance in the United States. 

Using CHPC resources, the Sohn group is developing high-resolution computational fluid dynamics (CFD) simulations to select the optimal operating conditions for testing and subsequently reduce the testing time and effort. Simulation results will be used to analyze the results from the flash reactors. Also of high importance, the results of the simulations will assist in the subsequent design of an industrial-scale pilot facility and eventual full-scale commercial plant.
