Description
Advanced capabilities available in nowadays batch systems are fundamental for
operators of high-performance computing centers in order to provide a high-
quality service to their local users. Existing middleware allow sites to expose
grid-enabled interfaces of the basic functionalities offered by the site’s
computing service. However, they do not provide enough mechanisms for
addressing the operational and scalability-related issues which are necessary
for offering the same quality of service to the site’s grid users.
This paper will present an overview of those issues and a proposed set of
features required for the batch systems integration to a grid infrastructure.
Then, we will describe a generic software framework that facilitates the
implementation of those features. The framework is designed to interact with
different grid execution services on one hand and with different batch systems
on the other hand. Specialization is done via Java plug-ins, XSL plug-ins and
XML configuration files.
To illustrate the benefits of the framework features, an example of its usage for
interfacing our site’s home-grown batch system (BQS) to the EGEE grid
execution service (gLite CE) will also be presented. In particular, we will
describe how the operational needs are addressed by the reusable
components of the framework.
