摘要：We report our experience of developing a QCD code on a CELL BE machine. First we describe
what CELL BE is, and why it is worthwhile studying the possibility of simulating lattice QCD
on this new multicore processor. Then we discuss our code development process and the performance
of fermion matrixvector calculations, which appear in a standard conjugate-gradienttype
solver. Our first result, 20 GFLOPS, is far from the theoretical peak speed of 400 GFLOPS.
We discuss the cause of this low value and a possible remedy.
