USATLAS Computing Facility Usage Policy

Condor Monitoring and Information (Auth required) BNL USATLAS Computing Facility has installed Condor (version 6.6.8) on all Linux compute nodes in ACF for use in controlling analysis and reconstruction jobs. This distributed batch queuing system implements sophisticated job scheduling and policy-driven resource allocation control, to ensure optimal performance. It can tolerate failure of any host or group of hosts, it provides job resubmission, checkpointing, job migration and many other features. It can also make use of specific hosts based on a time schedule or on the current load level. Condor has built-in fairshare scheduling, guaranteeing the access to resources for users or groups of users. Here is our usage policy.
