For my more significant computational tasks, I use the Meso Center HPC@LR leaded by the University of Montpellier and hosted at CINES. I provide here practical informations relative to my activity on this cluster HPC (High Performance Computing). HPC@LR provides a new cluster called Muse (formerly τ-au). The cluster can be touched with :
ssh firstname.lastname@example.org # Or: sshmuse # with the following alias defined in my $HOME/.profile file: alias sshmuse='ssh email@example.com'
As I use a ssh key, providing a keyword is not my concern. If you got your account on use but don’t have a ssh key, you can do on your linux client:
ssh-keygen -t rsa # (If you don't have any ssh key)
You may use a passphrase. But if you set one, you’ll have to write it. Then in all cases:
ssh-copy-id -i ~/.ssh/id_rsa.pub firstname.lastname@example.org
Now,you can connect directly with the same syntax as mine above.
I wrote a tutorial about how to play with Muse. It focuses on my scientific activity, but you may easily adapt it to your own.
