Submit  Machine Software

The CRS software consists of a pair of daemons that run as the reco-users on dedicated submit machines (currently rcrsuser1 for PHENIX / rcrsuser3 for STAR) in conjunction with the Condor batch software. One daemon is simply a logserver that writes log-messages from the running jobs to a folder in the reco-user's (local) home directory.

The new CRS Batch software was designed to allow users a transparent transition from old CRS batch software, whenever possible. In many instances, functionality and flexibility of the new software has been enhanced to address users' requests. An example is the ability of the new CRS batch software to leverage the use of commodity hardware (Intel-based servers) and open-source Linux OS to simplify the interface to the RCF/ACF mass storage system (HPSS).

New Features

The new CRS system has a number of enhancements and new features.
