摘要:We evaluate IBM’s Enhanced Cell Broadband Engine (BE) as a possible building block of a new
generation of lattice QCD machines. The Enhanced Cell BE will provide full support of doubleprecision
floating-point arithmetics, including IEEE-compliant rounding. We have developed a
performance model and applied it to relevant lattice QCD kernels. The performance estimates are
supported by micro- and application-benchmarks that have been obtained on currently available
Cell BE-based computers, such as IBM QS20 blades and PlayStation 3. The results are encouraging
and show that this processor is an interesting option for lattice QCD applications. For a
massively parallel machine on the basis of the Cell BE, an application-optimized network needs
to be developed.
