Workpoint : Used to get a better control over job production; Defined as a set of orderedclasses allocated to a worker; Runs only one job at a time, but Multiple workpoints on a worker. Example : workpoints definition for ccwasn01 (two processors SUN worker) 1@ccwasn01.in2p3.fr : T,S 2@ccwasn01.in2p3.fr : G,C,A 3@ccwasn01.in2p3.fr : I,R,J,P 4@ccwasn01.in2p3.fr : S,T,I,R Up to 4 jobs can run at the same time for the ccwasn01 worker. About 900 workpoints at the IN2P3 Computer Center. Workpoint Definition
Multiple AFS token support Group & user scheduling policies Resource management (CPU, memory, disk) Distributed environment (authentication service, privilege management and directory service made by internal products) Command line, API and graphical interfaces (JBQS) Features
