An operating system and applications software stack for Gordon is planned to start on Monday, June 24,2013. The upgrade process for the compute, vSMP, and I/O nodes is expected to take two days. Please note that this upgrade will not impact user data on the parallel lustre (Data Oasis) and the NFS filesystems. Compilers and MPI distributions will be upgraded as part of this process, so users will need to recompile applications after the upgrade is complete. SDSC staff will recompile/reinstall commercial packages, numerical libraries, and the currently available applications with the new compilers and MPI distributions.
An alternate login node will be setup, with the new software stack, in advance of the upgrade so users can compile their applications prior to the rollout. We will provide detailed information on the timeline, upgrade, and alternate login node as the start date approaches. Please email the XSEDE Help Desk with comments and questions.
