Real-Time Performance Support for Complex Grid Applications

One of the tasks in the EU IST int.eu.grid project is to create a pilot application which exploits Grid computational resources, based on the HEP application coming from the ATLAS project. When bringing the HEP application to the Grid, one of the problems is how to distribute the computations in an effective way to make the most of available Grid resources. Some support from monitoring is needed to assist in an optimal computation distribution. The HEP application is supported with monitoring information coming from two systems: JIMS and OCM-G. In this paper we present the issues of providing data for Real Time Dispatcher, based on the functionality of the two monitoring systems systems coupled into a single infrastructure. It is aimed to support fulfilling the real-time requirements posed by the HEP application.
