Jupyter notebook server on Odyssey

This document is to help you run Jupyter server remotely on compute nodes of the cluster and connect to your computational notebook using a local browser of your workstation/laptop.  Start a job: After login to the login node on Odyssey, you will need to start a job on the cluster. While you are setting up an environment, we recommend using an interactive…

New compute and partition reconfiguration

Fall greetings from RC! We are very pleased to unveil the new compute purchased by FAS as part of the Odyssey 3 project (https://www.rc.fas.harvard.edu/odyssey-3-the-next-generation/). This new compute hardware has been benchmarked at 0.5 petaflops, making it the fastest block of compute to date at Harvard. This hardware is now available on the cluster for people to use in these new…

Profiles in Delight: Scott Yockel

Name: Scott Yockel How long have you been at RC? Just in time for 110 inches of snow, I arrived in mid-January 2015. Having a young daughter in that much snow was tough. The stroller wheels were wider than a shovel. What led you here? To be a part of not just HPC, but to be a part of a…

Profiles in Delight: Mike Ethier

Name: Mike Ethier Job Title: Research Computing Associate How long have you worked for RC? Since its inception, which would be 2006. I started in 2001 working at Harvard on a smaller 200-300 core compute cluster. What led you to a career in HPC? I worked for a Northeast software reseller supporting the LSF queuing package for all types of…

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…
