Experience with a UNIX based batch computing facility for H1
Rainer Gerhards, U. Kruener-Marquis, Zbigniew Szkutnik · 1994
A UNIX based batch computing facility for the H1 experiment at DESY is described. The ultimate goal is to replace the DESY IBM mainframe by a multiprocessor SGI Challenge series computer, using the UNIX operating system, for most of the computing tasks in H1. Introduction With the advent of HERA, the first electron proton collider ever built, and its two large experiments H1 and ZEUS, the requirements for computing at the DESY laboratory in Hamburg increased considerably. These needs could not be fulfilled anymore with conventional mainframe computers. DESY, and the H1 experiment in particular, therefore started a project called DICE (DESY Integrated Computing Environment), closely following the SHIFT project at CERN [1]. The basic idea is to use the less expensive, high performance products provided by workstation industry, interconnected by a high performance network. DICE has been started about two years ago and, thanks to a close cooperation between the DESY computer center groups ...
