Welcome to the CSCS LCGTier2 web

Swiss LHC Computing Grid (WLCG) Tier-2

The CSCS LCG grid site is a dedicated resource for the Swiss Institute of Particle Physics (CHIPP), mainly to analyze data coming from the Large Hadron Collider (LHC) experiments at CERN. CSCS operates the Swiss Tier2 in the Worldwide LHC Computing Grid (WLCG) for CHIPP and provides support to the whole CHIPP community. It is also part of the infrastructure of the European Grid Initiative (EGI).

• PhoenixSetupAndSpecs gives a brief overview of the current installed services on the Tier-2. All computational resources are currently provided using the Piz Daint Supercomputer at CSCS.

Contact Information

Any question regarding the grid services hosted at CSCS can be asked directly to the Site Sysadmins: grid at cscs dot ch

Besides, if you want to contact site admins and also our VO Representatives, you can use: lcg at cscs dot ch

Also, two mailing lists are available for users of the grid cluster users:

• tier2-users at cscs dot ch: used for broadcasting downtimes and generally technically relevant messages for users who rely on the local resources of the cluster (e.g. on the storage accessibility). Subscribe/unsubscribe by sending mail to tier2-users-request at cscs dot ch (the email is read by a human operator, no need for special format).
• cms-users at cscs dot ch: will receive CMS specific messages in addition to all messages from the tier2-users list. Subscribe/unsubscribe by sending mail to cms-users-request at cscs dot ch (the email is read by a human operator, no need for special format).
