Owens Information Transition

Owens cluster will be decommissioned on February 3, 2025. Some pages may still reference Owens after Owens is decommissioned , and we are in the process of gradually updating the content. Thank you for your patience during this transition

GPFS filesystem Problem

We are having issues with GPFS filesystem (both project and scratch) on all clusters. It started around 3:08 PM, Oct 24, 2019. This also causes the inaccessibility of OSC OnDemand. We are not clear whether there are any job failures due to this problem. We are working to resolve the issue now. We will keep you posted and apologize for any inconvenience. Please contact oschelp@osc.edu if you have any questions.

Ls-dyna license outage

The ls-dyna license server that OSC is hosting has not been available since Oct 15, 2019. This outage is due to hardware failure on the server. We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.

TotalView Debugger Removal

The TotalView license server will shutdown and support of TotalView installed on OSC systems discontinued, along with the statewide licensing, on Nov. 1, 2019. Recently, a security vulnerability was found on the old license server software. OSC has a permanent Totalview license, but it is without the maintenance of the software. Thus, we cannot update the software to a new version. We have provided another HPC debugger, DDT, from ARM. Please consider migrating to DDT. Contact OSC Help for comments, questions or concerns.

Scratch Filesystem Errors Resolved

We have resolved a problem with the Scratch filesystem that gives errors "No space left on device". The cause is that the metadata subsystem is pretty full. The outage was caused be the rapid exhaustion of metadata storage space, the reason for the spike in metadata space utilization is unknown. The scratch filesystem has been returned to service after we worked with the vendor to implement a temporary workaround. We are working with the vendor to find the root cause and a permanent fix for the underlying problem. We apologize for any inconvenience this may cause.

Availability and Restrictions

Versions

The following versions of QGIS are available on OSC clusters:

Gaussian

Gaussian is a very popular general purpose electronic structure program. Recent versions can perform density functional theory, Hartree-Fock, Möller-Plesset, coupled-cluster, and configuration interaction calculations among others. Geometry optimizations, vibrational frequencies, magnetic properties, and solution modeling are available. It performs well as black-box software on closed-shell ground state systems.
