Batch Limit Rules
Memory Limit:
A small portion of the total physical memory on each node is reserved for distributed processes. The actual physical memory available to user jobs is tabulated below.
CHANGE OF DEFAULT MATLAB VERSION
OSC is changing the default version of MATLAB on all clusters from R2018a to R2018b effective Friday, April 26th. Several bugs exist in R2018a that have been addressed in R2018b. This change may cause some MATLAB jobs to fail. To review release notes for R2018b, please visit this link: https://bit.ly/2GvGjeM
To continue using R2018a in your jobs, you need to load the module "matlab/r2018a". If you need any assistance at all, please contact OSCHelp@osc.edu
SYSTEM DOWNTIME MAY 21, 2019
A downtime for all HPC systems is scheduled from 7 a.m. to 5 p.m., Tuesday, May 21, 2019. The downtime will affect the Pitzer, Ruby and Owens Clusters, web portals and HPC file servers. Login services, including my.osc.edu, access to storage and the HyperWorks license server hosted by OSC will not be available during this time. In preparation for the downtime, the batch scheduler will begin holding jobs that cannot be completed before 7 a.m., May 21, 2019. Jobs that are not started will be held until after the downtime and then started once the system is returned to production status.
Run your MD simulations on Anton
The Pittsburgh Supercomputing Center (PSC, www.psc.edu) is soliciting proposals for computer time on Anton 2, a special-purpose supercomputer for molecular dynamics (MD) simulation designed by D. E. Shaw Research (DESRES). Anton enables scientists to perform MD simulations of biomolecular systems nearly two orders of magnitude faster than the previous state of the art. To maximize the benefit of Anton to the scientific community, proposed projects should focus exclusively on questions that will be greatly advanced by the unique capabilities of Anton.
Network File Storage Maintenance
There will be an upgrade for the network file storage at OSC on April 8th. This upgrade is not expected to have an impact on day-to-day usage.
