The Linux farms at the RCF provide the bulk of the computation power that is required to process data that is collected by the experiments at the RHIC. There are two types of Linux farms at the RCF, the CRS and the CAS.

Historical data on the usage and performance of the Linux Farm can be viewed on our public Ganglia page. Users need their RCF password to access this page. For security reasons, this page can only be accessed from a browser running on a system within the BNL domain.

Historical data on the usage and performance of the Condor batch system can be viewed on our public Condor Monitoring page.

The CRS Linux farms are dedicated to reconstruction, that is the processing of raw event data, raw bits and bytes from the detectors, to create reconstructed event data, tracks, hits, collisions. The CRS farms are not available to general users at the RCF.

The CAS Linux farms are dedicated to the analysis of the reconstructed events. The CAS farms are a mix of interactive and batch systems that are available to general users at the RCF.

The sheer number of identical nodes in the Linux Farm insures the high availability of the system. Users should access different nodes if their preferred node is not available.
