PyMOL
PyMOL is a molecular visualization tool used to view, analyze, and create high-quality 3D images of biological molecules like proteins and DNA.
Availability and Restrictions
Versions
The following versions of PyMOL are available on OSC clusters:
OnDemand Shell App Not Working in Firefox 148
We are aware of an issue where the OnDemand Shell app is not functioning in Firefox 148. If you encounter this problem, please use a different browser to access the OnDemand Shell app until this issue is resolved. We have confirmed that Chrome, Edge, and Safari are working.
Duo Mobile Update Required
For OSC users who require Multi Factor Authentication (MFA), please update Duo Mobile to version 4.85.0 or later by Feb. 2, 2026 to avoid login issues. To check your version, open Duo Mobile and scroll to the bottom. To see whether your OSC account requires Duo, log into my.osc.edu and check whether you are in the Duo group. Questions? Open a case at https://support.osc.edu.
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."
