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 multicore 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.
