Odyssey 3, The Next Generation

Summary We are at the point where new technology requires us to update the operating system, and we have chosen to migrate the Odyssey HPC cluster to CentOS 7. This will impact all Odyssey Slurm compute and login nodes. Virtual machines used for web applications, etc. will not necessarily be impacted. This is the first thing in a long time.…

OpenMPI update: February 11th-13th

Starting Thursday, February 11th, we'll be updating the OpenMPI libraries in the new module system along with the MPI application set. The update should be done in about 2 days. If you load modules using the full name, (e.g. module load fftw/3.3.4-fasrc06), this should not affect you. If you load the "latest" module (e.g. module load fftw) you may be…
