PITZER EARLY USER PROGRAM APPLICATIONS OPEN

In preparation for the deployment of the Dell Pitzer Cluster in November 2018, OSC would like to invite members of the client community to be a part of the Pitzer Early User Program through an application process. Clients selected to participate would gain access to Pitzer hardware in advance of the public deployment, with the ability to run jobs at no charge. In exchange, OSC asks these users to work closely with our staff to identify problems in the environment. To be considered, please fill out the application here: https://bit.ly/2xqpJJq The applications will close October 5.

POSSIBLE OWENS OUTAGE

We have been experiencing an issue with the Ethernet switches in the Owens cluster, which may potentially kill the running jobs on Owens. We have been monitoring this issue closely and reserving nodes with the switch errors for emergency maintenance. So far, no running job has been killed due to this issue based on our monitoring. Oakley and Ruby clusters are not affected. A possible Owens outage will happen for the permanent fix of this issue. We'll provide updates as we learn more from the vendor. We apologize for any inconvenience this may cause you.

ROLLING REBOOT OF ALL THREE CLUSTERS STARTING SEPT. 4

Owens, Ruby, and Oakley clusters will have OS kernel and BIOS updates to address the latest Intel processor security vulnerabilities. As part of these updates it is necessary to update the OS distribution on Ruby and Oakley from Red Hat version 6.9 to 6.10. These changes will be applied via rolling reboots of compute nodes. Owens and Ruby will also have a software refresh at this time. For the most updated information on the software refresh, please see https://bit.ly/2PANrtZ

ROLLING REBOOT OF OWENS AND RUBY STARTING AUGUST 6

We will have rolling reboots of Owens and Ruby clusters including login and compute nodes, starting from 8 AM Monday, August 6, 2018. This rolling reboot is to make the latest CUDA 9 and dependent software available with the updated device driver, for the preparation of the software refresh at the end of August. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. The Oakley cluster will not be affected.

DOWNTIME FOR ALL CLUSTERS JULY 17

A downtime is scheduled for all HPC systems starting July 17, 2018, beginning at 7:00 A.M. and scheduled to finish by 5 P.M. The downtime will affect the Oakley, Owens, Ruby clusters. Login services and access to storage will not be available during this time. In preparation for the downtime the batch scheduler will begin holding jobs that cannot complete before July 17 at 7:00 A.M.

ROLLING REBOOTS OF ALL CLUSTERS STARTING JUNE 19

We will have rolling reboots of three clusters (Owens, Ruby, and Oakley) including login and compute nodes, starting from 8 AM Tuesday, June 19, 2018. The rolling reboots will address recent Kernel vulnerabilities patched by RedHat. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. For the most updated information, please see https://bit.ly/2sRW3Ts
