Abstract

The Cell Broadband Engine (Cell BE) multi core processor from the STI consortium of Sony, Toshiba and IBM is a powerful but complex processing device that has attracted much attention since its inclusion in Sony Playstation (PS3) gaming consoles. We report on some performance experiments using the multi-core Synergistic Processing Elements (SPE) concurrency capabilities of this chip. We compare performance and software implementation issues with conventional cluster computing techniques such as message-passing, in exploiting clusters of Cell BE processors for scientific simulations. We discuss performance and user programming issues for some hybrid solutions on clustered PS3 computers running Linux.

Keywords: Cell BE processor; multi-core; SPE; PS3; cluster.
