Updates to Ruby Application Software - September 2015

OSC is refreshing the software stack on Ruby on September 15, 2015 (during the scheduled downtime). During the software refresh, some default versions are updated to be more up-to-date. Information about the old and new default versions, as well as all available versions of each software package will be included on the corresponding OSC software webpage. See https://www.osc.edu/supercomputing/software-list.

Software Refresh

OSC timely installs new software versions on OSC systems, and periodically do coordinated software refresh (update the default versions to be more up-to-date and remove some versions that are quite out of date) on OSC systems. While we encourage everyone to use up-to-date software, the old defaults will still be available till the next software refresh, in case some users prefer to use the old defaults. The software refresh is usually made during the scheduled downtime, while we will send out notifications to all users ahead of time for any questions/suggestions/concerns.

CCAPP Condo on Ruby Cluster

Condo model refers to that the participants (condo owners) purchase one or more compute nodes for the shared cluster while OSC provides all infrastructure, as well as maintenance and services. CCAPP Condo on Ruby cluster is owned by the Center for Cosmology and AstroParticle Physics, at OSU. Prof. Annika Peter has been heavily involved in specifying requirements.

Hardware

Detailed system specifications:

  • 21 total nodes

    • 20 cores per node
