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.

System Downtime October 8, 2019

A downtime for all HPC systems is scheduled from 7 a.m. to 5 p.m., Tuesday, October 8, 2019. The downtime will affect the Pitzer, Ruby and Owens Clusters, web portals, and HPC file servers.
