Service Status:
| NoMachine: | 03/19/25 9:00-03/26/25 0:00 PDT Retired NoMachine will become unavailable for users on March 19, 2025. For reasons related to the licence and NoMachine version this date cannot be extended. As we move away from NoMachine as our virtual desktop solution, NERSC will be moving to ThinLinc. ThinLinc provides secure remote access to NERSC resources including Perlmutter and the Data Transfer Nodes, allowing you to connect to a virtual desktop environment from anywhere.
