Change in use of /scratch/local on compute nodes
Effective Tuesday July 21 on lonepeak
posted 7 July 2020
Access permissions to /scratch/local will be set such that users will no longer be able to created directories in the top level /scratch/local directory. Instead, as part of the slurm job prolog (before the job is started), a job level directory, /scratch/local/$USER/$SLURM_JOB_ID , will be created. After the end of the job, in the slurm job epilog, this job level directory will be removed.
Once we confirm there are no issues on lonepeak, we will make the same change on the other clusters (kingspeak, notchpeak, ash and redwood)

Clean Coal: Powered by Exascale
By Philip J. Smith and Michal Hradisky, CCMSC
The mission of the Carbon-Capture Multidisciplinary Simulation Center (CCMSC) at the University of Utah is to demonstrate the use of exascale uncertainty quantification (UQ) predictive simulation science to accelerate deployment of low-cost, low-emission electric power generation to meet the growing energy needs in the United States and throughout the world. The two main objectives, advancing simulation science to exascale with UQ-predictivity in real engineering systems and use of high-performance computing (HPC) and predictive science to achieve a societal impact, are linked together through an overarching problem: simulation of an existing 1,000 MW coal-fired ultra-supercritical (USC) boiler and simulation of a design 500 MW oxy-coal advanced ultra-supercritical (AUSC) boiler.
