ARCHIVED: On XSEDE, what is Comet (SDSC)?

This content has been archived, and is no longer maintained by Indiana University. Information here may no longer be accurate, and links may no longer be available or reliable.

Comet is hybrid computing cluster, featuring CPU, GPU, and large-memory nodes, operated as an Extreme Science and Engineering Discovery Environment (XSEDE) digital service by the San Diego Supercomputer Center (SDSC).

For system specifications and user documentation, see the Comet User Guide.

Note:

Trial allocations are available for potential users who want to evaluate Comet before requesting Startup or Research allocations. A trial allocation provides 1,000 service units (SUs) and expires after six months. For more, see the Trial allocations section of the XSEDE Allocations Overview.
By July 1, 2017, the SDSC expects to have 36 additional GPU nodes in production service on Comet. The new GPU nodes are substantially faster than the existing ones, achieving more than twice the performance for some applications. Consequently, researchers wanting to use Comet's GPUs must request separate "Comet GPU" allocations (researchers with existing Comet allocations may convert some of their SUs to GPU-hours). For details, see the Using GPU nodes section of the Comet User Guide.

For more about XSEDE compute, advanced visualization, storage, and special purpose systems, see the Resources Overview, Systems Monitor, and User Guides. For scheduled maintenance windows, outages, and other announcements related to XSEDE digital services, see User News.
