General-Purpose Parallel Computing in a High-Energy Physics Experiment at CERN

The CERN experiment NA48 is actively using a 64-processor Meiko CS-2 machine provided by the ESPRIT project GP-MIMD2, running, as part of their day-to-day work, simulation and analysis programs parallelized in the framework of the project. The CS-2 is also used as a data warehouse for NA48: data coming at high rate from the experiment are processed in real-time and written to DEC DLTs using the Meiko Parallel File System (PFS) as a high-speed I/O buffer.
