Singularity

Singularity is a container system designed for use on High Performance Computing (HPC) systems. It allows users to run both Docker and Singularity containers.

From the Docker website: "A container image is a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries, settings."

ROLLING REBOOTS OF OAKLEY AND RUBY STARTING OCT 9

We will have rolling reboots of Oakley and Ruby clusters starting from 8:30AM on Monday October 9, 2017. A rolling reboot of Owens will be scheduled for a later date. These rolling reboots will address recent security vulnerabilities patched by RedHat. These 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.

LAPACK

LAPACK (Linear Algebra PACKage) provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.

Availability and Restrictions

A highly optimized implementation of LAPACK is available on all OSC clusters as part of the Intel Math Kernel Library (MKL). We recommend that you use MKL rather than building LAPACK for yourself. MKL is available to all OSC users.

HOWTO: Use Docker and Singularity Containers at OSC

It is now possible to run Docker and Singularity containers on the Ruby, Owens and Pitzer clusters at OSC. Single-node jobs are currently supported, including GPU jobs; MPI jobs are planned for the future.

From the Docker website:  "A container image is a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries, settings."

Rolling Reboot of Owens Nodes will begin September 11 at 9am

In order to upgrade the kernel, we will conduct a rolling reboot of all Owens nodes. This will begin at 9 a.m. on September 11 and continue until all nodes have been rebooted. The login nodes will be rebooted first.This rolling reboot won't affect any running jobs, but users may experience longer queue wait times than usual on the Owens cluster. Please contact oschelp@osc.edu if you have any questions.

HOWTO: submit homework to repository at OSC

This page outlines a way a professor can set up a file submission system at OSC for his/her classroom project.

Usage for Professor

After connecting to OSC system, professor runs submit_prepare as

$ /fs/scratch/xwang/bin/submit_prepare

Follow the instructions. It will create a designated directory where students submit their assignments, as well as generate submit for students used to submit homework to OSC, both of which are located in the directory specified by the professor.

System Downtime

A downtime for all HPC systems is scheduled from 7 a.m. to 5 p.m. Tuesday, Aug. 22, 2017. The downtime will affect the Oakley, Ruby and Owens Clusters, web portals, and HPC file servers. Login services, including my.osc.edu, 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 be completed before 7 a.m., August 22. Jobs that are not started will be held until after the downtime and then started once the system is returned to production status.
