Compute: Voltar

voltar.nic.uoregon.edu

Pascal / Volta-class GPU testbed system. Has a local license for a GPU-accelerating PGI compiler.

Voltar also has (at least temporarily) an A100-80GB GPU, nVidia's most powerful yet.

Voltar runs the DCV remote high performance desktop server. To utilize this, while SSHed into Voltar, use

user$ dcv help # show all commands
user$ dcv list-sessions
user$ dcv create-session FOO
user$ dcv close-session FOO

Then, take your browser to https://voltar.nic.uoregon.edu:8442/#FOO and you will be able to log into to a CentOS desktop using your credentials, in your browser.

Please do not leave sessions open forever when you are done. Our license for sessions is not unlimited!
