DESIGN AND IMPLEMENTATION OF THE GLITE CREAM JOB MANAGEMENT SERVICE

Job execution and management is one of the most important functionality provided by every modern Grid middleware. In this paper we describe how the problem of job management has been addressed in the gLite middleware by means of the CREAM and CEMonitor services. CREAM (Computing Resource Execution and Management) provides a job execution and management capability for Grid systems, while CEMonitor is a generalpurpose asynchronous event notification framework. Both services expose a Web Service interface allowing conforming clients to submit, manage and monitor computational jobs to a Local Resource Management System.
