High Energy Physics on DECPeRLe

High-Energy Physics on DECPeRLe-1 Programmable Active Memory Laurent Moll Jean Vuillemin y Philippe Boucard z Abstract The future Large Hadron Collider (LHC) to be built at CERN 1 , by the turn of the millenium, provides an am- ple source of challenging real-time computational prob- lems. We report here some results from a collabora- tion between CERN EAST 2 (RD-11) group and DEC- PRL PAM 3 team. We present the implementations of the three foremost LHC algorithms on DECPeRLe-1 [2]. Our machine is the only one which presently meets the requirements from CERN (100 kHz event rate), except for another dedicated FPGA-based board built for just one of the algorithm [3]. All other implementations based on single and multiprocessor general purpose com- puting systems fall short either of computing power, or of I/O resources or both. 1 Introduction 1.1 High-Energy Physics The community of High-Energy Physics is about to de- cide to go forward with the next generation collider to be built at CERN, the LHC. With this new instrument, it will be possible to observe proton-proton collisions of 8000 GeV, an energy not attainable today.
