STAR 2.7.9a is available

Monday, September 27, 2021 - 12:45pm

STAR 2.7.9a has been installed with gnu/10.3.0 compilers on Owens and Pitzer.  Usage is via the module star/2.7.9a.  For help loading an installation, use the command:  "module spider star/2.7.9a".  That command also emits information on the available executables and installation details.

System Downtime Sept 28, 2021

A downtime for all OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, September 28, 2021. The downtime will affect the Pitzer and Owens Clusters, web portals, state-wide licenses, HPC file servers, and MyOSC. Login services will not be available during this time. In preparation for the downtime, jobs that cannot be completed before 7 a.m., September 28, 2021 will not start. Jobs that are not started on clusters will remain until after the downtime and then will be queued to start once the system is returned to production status.


HMMER is used for searching sequence databases for sequence homologs, and for making sequence alignments. It implements methods using probabilistic models called profile hidden Markov models (profile HMMS). HMMER is designed to detect remote homologs as sensitively as possible, relying on the strength of its underlying probability models.

Availability and Restrictions


HMMER is available on the OSC clusters. These are the versions currently available:

Rolling reboots on owens and pitzer starting 18 Aug 2021

We will have rolling reboots of Owens and Pitzer cluster, including login and compute nodes, starting from 9am on August 18, 2021. The rolling reboot is for urgent security updates. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. User will also expect about a 10 minute outage of login nodes during the reboot of login nodes. If there are interactive jobs started from a login node and that login node is rebooted, then the job will be killed.
