OWENS SCHEDULED MAINTENANCE MARCH 16TH

There is scheduled maintenance to take place on the Owens cluster this Saturday, March 16th. This maintenance will reduce the number of usable nodes available on the Owens cluster on Saturday, March 16th. The Owens cluster will be back to full operational status at 6pm that same day. This will not have a significant impact on jobs submitted to the Owens cluster, but there may be an increase in the average queue time since fewer nodes will be available.

XDMOD JOB METRICS TOOL NOW AVAILABLE

XDMoD, which stands for XD Metrics on Demand, is an NSF-funded open source tool that provides a wide range of metrics pertaining to resource utilization and performance of high-performance computing (HPC) resources, and the impact these resources have in terms of scholarship and research. Access it at xdmod.osc.edu and log in with your OSC credentials. For more information and details on how to use this tool, see our documentation: https://bit.ly/2EhT3EI

SCARCE RESOURCES - GPU AND LARGE MEMORY NODES

Please be aware that the GPU and large memory resources on Owens and Pitzer are very busy and that can lead to long queue wait times. If you do not need these resources for your jobs, using the standard compute nodes will ensure your jobs start sooner and the scarcer resources are available for those whose jobs require them. If you are unsure whether you need these resources for your work, please contact us at oschelp@osc.edu
