Description
Modern GRID middlewares are built around components providing basic
functionality, such as data storage, authentication and security, job
management, resource monitoring and reservation. In this paper we
describe the Computing Resource Execution and Management (CREAM)
service. CREAM provides a Web service-based job execution and
management capability for Grid systems; in particular, it is being
used within the gLite middleware. CREAM exposes a Web service
interface allowing conformant clients to submit and manage
computational jobs to a Local Resource Management System. We developed
a special component, called ICE (Interface to CREAM Environment) to
integrate CREAM in gLite. ICE transfer job submissions and
cancellations from the Workload Management System, allowing users to
manage CREAM jobs from the gLite User Interface. This paper describes
some recent studies aimed at measuring the performance and the
reliability of CREAM and ICE, also in comparison with other job
submission systems. We discuss recent work towards enhancing CREAM
with a BES and JSDL compliant interface.
