Grid Software Detection Proceedings of the Cracow Grid Workshop 2009 Maximilian Berger David Gstir Thomas Fahringer Distributed computational environments provide heterogenous environments, which are under different administrative domains. As such, each execution com- ponent may have a different configuration and installed software. Information systems describing the software installation are mostly manually administrated, and as such are often incomplete or out of date. In this paper we present an automated environment to schedule and run test jobs in distributed execution environments. It offers a plug-in system, which allows the users to add detection plug-ins for specific software. It also provides a crawler tool which schedules and executes the test jobs. In addition, it offers a query-API to select execution sites based on the checked requirements. The paper concludes with a verification of the proposed software crawling system by showing a survey of the installation of Java software in the EGEE Grid. This survey checks for the installed version and correct installation of the Java software. It provides a real-life test case for the proposed system. 978-83-61433-01-9 36-43 2010 CGW 09: Cracow Grid Workshop Oct 12-14, 2009
