| Summary: | The Grid technologies are in ongoing development. Using current Grid toolkits like the Globus toolkit [1] gives one the possibility to build up virtual organizations as defined in [2]. Although these tookits are still under development and do not feature all functionality, they can already now be used to set up an efficient computing environment for physics collaborations with only moderate work. We discuss in this paper the use of such a computing structure in two running experiments- the AMANDA (AMANDA = Antarctic muon and neutrino detector array) neutrino telescope and the DØ experiment at Tevatron, Fermilab. One of the main features of our approach is to avoid reprogramming of the existing software which is based on several programming languages (FORTRAN, C/C++, JAVA). This was realized with software layers around the collaboration software taking care about in- and output, user notification, tracking of running jobs, etc. A further important aspect is the resolution of library dependencies, which occur when a user runs self-compiled jobs on machines where these libraries are not installed. These dependencies are also resolved with these layers. 1. |
