OSCusage

Introduction

OSCusage is a command developed at OSC for use on OSC's systems.  It allows a user to see information on their project's usage, including different users and their jobs.

PyTorch

 PyTorch is an open source machine learning framework with GPU acceleration and deep neural networks that is based on the automatic differentiation in the Torch library of tensors.

Rolling Reboot

We will have rolling reboots of all three clusters (Owens, Ruby, and Pitzer) including login and compute nodes, starting from 9:30 AM Wednesday, June 05, 2019. The rolling reboots will address the caching problems on the file systems. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.

CHANGE OF DEFAULT MATLAB VERSION

OSC is changing the default version of MATLAB on all clusters from R2018a to R2018b effective Friday, April 26th. Several bugs exist in R2018a that have been addressed in R2018b. This change may cause some MATLAB jobs to fail. To review release notes for R2018b, please visit this link: https://bit.ly/2GvGjeM To continue using R2018a in your jobs, you need to load the module "matlab/r2018a". If you need any assistance at all, please contact OSCHelp@osc.edu

SYSTEM DOWNTIME MAY 21, 2019

A downtime for all HPC systems is scheduled from 7 a.m. to 5 p.m., Tuesday, May 21, 2019. The downtime will affect the Pitzer, Ruby and Owens Clusters, web portals and HPC file servers. Login services, including my.osc.edu, access to storage and the HyperWorks license server hosted by OSC will not be available during this time. In preparation for the downtime, the batch scheduler will begin holding jobs that cannot be completed before 7 a.m., May 21, 2019. Jobs that are not started will be held until after the downtime and then started once the system is returned to production status.
