Local ATLAS Computing at TRIUMF
For our local group's computing needs, distinct from the Tier 1, we run the following:
- TRIUMF Tier-3 Server which has many current release Updates installed. Sometimes we even run KitValidation on them and make sure they work.
- Tier-3 Cluster TRIUMFAtlasTier3
The Tier-3 server runs some user services for ATLAS-Canada, in addition to the TRIUMF Tier-3 services. We won't discuss those here. For the local group, the relevant services on the Tier-3 server are:
- Athena releases installation (for both 32-bit and 64-bit architectures)
- gLite User Interface
How to setup your desktop / laptop to use ATLASLocalRootBase
Most of the desktop machines for the ATLAS group at TRIUMF are combined in a cluster. If you have an account on one of them, you should be able to log into it from any of them and access your home directory as if you were on your own machine (the only catch is that your own machine, where the home directory is physically, has to be working at the time). The cluster master is a virtual machine on UPS. The data/scratch disks are mostly mounted so that they can be seen from all of the nodes in the cluster.
Using PROOF has some information on how to use the PROOF cluster, which is no longer available.
Local cluster setup notes details for adding user accounts and cluster nodes
We finally managed to upgrade the cluster to SL5. Of course, SL6 is getting pretty mature now...
Setting up FreeNX - you can use this to log in to ds02 or ds03 from one of the iGel thin clients we have borrowed.
