2016 Storage Service Upgrades

On July 12th, 2016 OSC migrated its old GPFS and Lustre filesystems to new Project and Scratch services, respectively. We've moved 1.22 PB of data, and the new capacities are 3.4 PB for Project, and 1.1 PB for Scratch. If you store data on these services, there are a few important details to note.

BMI Condo on the Owens Cluster

"Condo model" refers to an arrangment when a client leases one or more compute nodes for the shared cluster while OSC provides all infrastructure, as well as maintenance and services. BMI's Condo on the Oakley Cluster is leased by the Biomedical Informatics Institute at The Ohio State University. This condo is a temporary "bridge" condo to server the community needs until the Owens Cluster is available.

Messages from qsub

We have been adding some output from qsub that should aid you in creating better job scripts. We've documented the various messages here.

NOTE

A "NOTE" message is informational; your job has been submitted, but qsub made some assumptions about your job that you may not have intended.

Migrating jobs from Glenn to Oakley or Ruby

This page includes a summary of differences to keep in mind when migrating jobs from Glenn to one of our other clusters.

Hardware

Most Oakley nodes have 12 cores and 48GB memory. There are eight large-memory nodes with 12 cores and 192GB memory, and one huge-memory node with 32 cores and 1TB of memory. Most Ruby nodes have 20 cores and 64GB of memory. There is one huge-memory node with 32 cores and 1TB of memory. By contrast, most Glenn nodes have 8 cores and 24GB memory, with eight nodes having 16 cores and 64GB memory.
