Pitzer Production Deployment December 4

Pitzer, OSC's latest cluster, will be deployed to full production status on Tuesday, December 4. All users will have access to the cluster and will be able to submit jobs. For details on how to modify your jobs to run on Pitzer, please see https://bit.ly/2P7G4Zz For general information about the new cluster, please visit osc.edu and see our Cluster Computing pages. If you have any questions, please contact OSC help https://bit.ly/29AXmdf

Services have been restored after switch failure

At about 1:50 am on November 14th, 4:05 am on November 17th, and 5:00 am on November 18th, OSC experienced three separate major switch failures. We restored all the services after each outage, and have completed the update to the NetApp appliance that provides the home directory service to address a separate bug triggered by the outage. We are still working with the vendor for the network switches on a permanent resolution to the bug that has caused these interruptions. We will continue to keep you informed.

Switch failure on Nov 17 2018

At about 4:05 am on November 17th, OSC experienced a major switch failure which resulted in the home directory service and GPFS file systems being disrupted. Most services were back up around 10 am, but some users may still be seeing stale file handles on GPFS. We are still working on recovering GPFS clients. For more updates, see: https://bit.ly/2DIXr1G

Reboot of NetApp as part of an upgrade on November 19

We will have a reboot of the NetApp as part of an upgrade, starting from 9:30 AM on Monday, November 19, 2018, to address a bug that causes NetApp issues caused by the network switch outage we had on Nov 14, 2018. Any cluster nodes, OnDemand service, and all filesystems won't be impacted by the reboot. We also do not expect any disruptions to users' jobs due to this reboot.

Major network switch outage on November 14, 2018

At about 1:50 AM on November 14th, OSC experienced a major switch failure which resulted in the home directory service being disrupted. As a result, the home directories were offline and all logins were failing to all clusters. All user-facing issues have been resolved and the services are back. Running jobs may recover, but please look at job output to verify correctness. Some jobs experienced failures and will need to be resubmitted. For more information, see: https://bit.ly/2FlCZFD

Transmission3d

Transmission3d is a 3-dimensional, multi-body gear contact analysis software capable of modeling complex gear systems developed by Ansol (Advanced Numeric Solutions). Multiple gear types, including: Helical, Straight Bevel, Spiral Bevel, Hypoids, Beveloids and Worms can be modeled. Multiple bearing types, as well as complex shafts, carriers and housings can also be modeled with the software. A variety of output data options including tooth bending stress, contact patterns, and displacement are also available.

NBO

The Natural Bond Orbital (NBO) program is a discovery tool for chemical insights from complex wavefunctions. NBO is a broad suite of 'natural' algorithms for optimally expressing numerical solutions of Schrödinger's wave equation in the chemically intuitive language of Lewis-like bonding patterns and associated resonance-type 'donor-acceptor' interactions.

Availability and Restrictions

Versions

NBO is available on Owens. The versions currently available at OSC are

Rosetta

Rosetta is a software suite that includes algorithms for computational modeling and analysis of protein structures. It has enabled notable scientific advances in computational biology, including de novo protein design, enzyme design, ligand docking, and structure prediction of biological macromolecules and macromolecular complexes.
