Brief Network Maintenance 7AM Dec 16
We will be conducting network maintenance on Tuesday, December 16, at 7:00 AM EST to prepare for the January 6 scheduled downtime. There is a low probability of brief disconnection for external connections (SSH/OnDemand) to the HPC environment. Running jobs will continue to run. We expect this operation to be seamless.
HOWTO: Use Docker and Singularity Containers at OSC
It is now possible to run Docker and Apptainer/Singularity containers on all clusters at OSC. Single-node jobs are currently supported, including GPU jobs; MPI jobs are planned for the future.
From the Docker website: "A container image is a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries, settings."
