[edit] ATHENA IS CHANGING!!!

The Meiosis of Athena has begun. The various collaborators around Athena have completed their primary research objectives as group. The lessons of this experiment have set the stage for projects like the eScience HYAK as well as helped shape future research hardware strategies.

Funding sources have changed which require us to evolve Athena. The hardware will remain connected and in the same place, but we're transforming the way Athena operates to match the current funding climate. More on the Meiosis of Athena here...

[edit] Athena Overview

The Athena cluster is comprised of 140 compute nodes linked together by a high speed InfiniBand network fabric. The theoretical peak performance of the system is over 10 TeraFlop/s (10 trillion floating point operations per second). All compute nodes are connected to 23.7 TB of shared storage. There is also a front-end node (athena0.npl.washington.edu) for user login, compilation, and job submission. The compute nodes are accessed via batch jobs submitted to PBS from athena0.

[edit] Science Output

The Athena Publications Page provides a list of publications made possible by the Athena cluster as well as a form by which Athena users can enter their new publication data. It is very important that anyone who has used Athena to generate material for published work register this material with the publications database. We need this information to continue to generate funds for Athena-related operations and upgrades.

Disk Space and Node Allocation. Describes how the storage and compute nodes are allocated among different user groups.

Current Disk Utilization

After you learn how to compile programs and submit jobs on Athena, we highly recommend reading the new section on Getting the Most out of Athena under "Performance Considerations" below. This contains important information on how to get the best performance out of Athena's compute nodes and storage components.
