Tusker & OSG
|New Tusker Cluster|
The goal of this cluster is to enable higher throughput of local user jobs while enabling backfilling of grid jobs. The current breakdown of local and grid jobs can be found on the hcc monitoring page.
A common complaint among our local users is interference between processes on the nodes. To address this, we patched torque to add cgroups support for cpu isolation. Memory isolation should come into production in the next few weeks. This will affect grid jobs by locking down their usage to only a single core.
Nebraska's goal is to support all OSG VO's, and give them equal priority (albeit lower than local users). All OSG VO's are welcome to run on Tusker.

Stay tuned, the next year should be exciting...
