Information in this page is not yet complete nor final. It will be updated following the progress of

the Alps system deployment at CSCS
C2SM's adaptation to this new system

Supported vClusters¶

This page is hosting information about C2SM supported vClusters (not all CSCS vClusters).

Access¶

Connection to vClusters happens as for any other CSCS machine, e.g. ssh santis.cscs.ch with a ProxyJump on ela.cscs.ch. A section in the ~/.ssh/config could look as follows:

~/.ssh.config

Host ela
  Hostname ela.cscs.ch
  User cscsusername
  IdentityFile ~/.ssh/cscs-key

Host balfrin* daint* santis* todi*
  Hostname %h.cscs.ch
  User cscsusername
  IdentityFile ~/.ssh/cscs-key
  ProxyJump ela

This would allow standard connections like ssh santis but also specifying the login node like ssh santis-ln002 if needed. Replace cscsusername with your actual user name.

Daint¶

Daint (Alps) is the vCluster dedicated to the User Lab. It is currently accessible at daint.alps.cscs.ch (until the current Piz Daint gets decommissioned), so connect with ssh daint.alps with the ssh settings above.

Even though Weather and Climate also has the dedicated vCluster Santis (see below), traditional projects might also land on Daint.

Uenvs¶

List of currently supported Uenvs on Daint:

uenv	activity	Remark
icon-vx:rcy	build and run ICON	Not deployed (yet?)
netcdf-tools/2024:v1-rc1	pre- and post-processing tools

Santis¶

Santis has not been deployed yet.

Santis is dedicated to Weather and Climate. It might, at the beginning, only host EXCLAIM and related projects.
