We report what we learned in developing a QCD (Quantum Chromo Dynamics) code on Cell/B.E., i.e., necessary procedures to realize an efficient high performing program and an obstacle to prevent the peak performance of the Cell/B.E.. We found that we can almost reach to the machine peak performance, and the bottle-neck is the memory bandwidth which reduces the efficiency about one tenth. We discuss the next task for constructing a satisfactory problem solving environment of QCD.
