Abstract

Some of the significant issues associated with the development of quantum chromatodynamics parallel computing on the cell broadband engine (QPACE) projects are discussed. The quantum chromatodynamics QPACE projects use a compute node, based on IBM's PowerXCell 8i multicore processor and couples it to a specifically designed network processor in which each node is connected to its nearest neighbors in a 3D toroidal mesh. A Xilinx Virtex-5 field-programmable gate array (FPGA) is used, to facilitate the network processor's implementation. The QPACE project converts the parallel performance into a linear form in the number of nodes. It also enables programmers to divide an algorithm, implemented on a specific architecture into microtasks, which are performed by the model's processing devices.
