Development of QCD-code on a CELL Machine

Presenter: Atsushi Nakamura — RIISE, Hiroshima University

Shinji Motoki and Atsushi Nakamura

We report performance of fundamental parts of QCD code on a CELL BE (Broadband Engine). CELL is a new multicore processor, which was developed by SONY, IBM and Toshiba for a game machine, PS3. It consists of one PPE (PowerPC Processor Element ) and 8 SPEs (Synergistic Processing Element), and its theoretical peak floating speed is 200 GFLOPS. We are developing a QCD code on IBM SQ20 which has two CELLS. We show our parallel strategy and performance measurements of the calculations and communications. We discuss also present limitations of the CELL calculation.
