U.S. ATLAS Resource Allocation Committee


"The RAC committee decides priorities on the usage of computing resources (CPU and storage) funded by the U.S. Research Program. Most of these resources are pledged to the WLCG through a U.S. MoU. Overall ATLAS priorities for these pledged resources are set by the ATLAS CREM committee. The RAC will set resource allocations of pledged resources based on CREM guidelines. There are additional resources funded by the U.S. Research Program which are not pledged to the WLCG. The RAC will allocate these resources based on needs of U.S. funded physicists, in consultation with the U.S. physics community (via the U.S. physics forums and other channels), U.S. Operations Team and the U.S. Facilities Manager. Examples of the use of U.S. resources are 'regional production', 'group analysis', large scale MC production (1 billion SM sample in 2009 used for UAT09). We expect the RAC to play a central role in managing efficient usage of U.S. Research Program funded resources."

Meetings are held by phone on an "as needed" basis. The scheduled meeting time is Thursday afternoon at 13:30 ET. All interested US ATLAS members are welcome to join meetings.

RAC meeting agendas are available in the "Physics Support and Computing" Indico category.

Mailing List

The mailing list usatlas-rac-l@lists.bnl.gov is used to announce meetings and circulate information between meetings. All interested US ATLAS members are welcome to subscribe (subscription is moderated to avoid SPAM).

Disk Space for US Analysis Activities

An up-to-date overview of ATLAS space tokens is available at https://twiki.cern.ch/twiki/bin/view/AtlasComputing/StorageSetUp

Note that LOCALGROUPDISK is not counted in the pledge to ATLAS. The RAC and the US Operations Team are committed to making LOCALGROUPDISK a valuable resource for US physics and performance activities. See USAtlasStorageSetUp - LOCALGROUPDISK in the US for the evolving information on how to use LOCALGROUPDISK.

US Regional Production

US Regional Production can produce datasets valid for ATLAS results.
