Researchers submit proposals to the consortium via the XSEDE user portal. The cluster does include some additional special-purpose nodes that are not shown in the table. Prototype procedure status_exit ( code : integer ) Arguments code. Abstract. The core-hours used for a job are calculated by multiplying the number of processor cores used by the wall-clock duration in hours. CISL. New Employee Assistance. Urgent updates are scheduled with as much advance notice as possible. CISL’s monitoring of Cheyenne indicates a significant improvement in the job failure rates since last Thursday’s outage when several hardware components were replaced. The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed for both atmospheric research and operational forecasting applications. Cheyenne continues to experience system stability issues introduced after the recent software upgrade, and vendors’ Level-3 support and CISL staff continue to aggressively work the problems. PZ and YW were funded by the NSF (AGS-1406962). status_exit. 2) The problem from last Sat was an inadvertent denial of service attack from someone (still unknown) trying to down load the entire 30 TB of inputdata, which is a) unwise, and b) unnecessary. This table shows the status of Casper nodes that are available to all users. CISL provides the qcmd script for running CESM and WRF builds and other compiles in addition to compute jobs on batch nodes. The Phase 5 effort saw a dramatic increase in the number of experiments that were performed and the number of variables that were requested compared to its previous generation, Phase 3. Can we improve the user experience? The presentations in CISL's booth included science and computing talks about CESM, aerodynamics and wind energy simulations on Yellowstone, and GPU applications in data assimilation.
