Owens

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.

Rolling reboot of Owens starting from Oct 10, 2019

We are having rolling reboots of Owens cluster including login and compute nodes, starting from October 10, 2019, to update Kernel and root filesystem. The rolling reboots won't affect any running batch jobs, but users may experience longer queue wait time than usual on Owens. A reboot of the Owens login nodes is scheduled at 8AM on Friday, October 11, 2019. The outage is expected to last 5-10 minutes and SSH sessions on Owens will be disconnected during the outage. 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.

Versions

The following versions of QGIS are available on OSC clusters:

Gaussian

Gaussian is the most 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.
