As demand for supercomputer performance grows faster than the rate that improvements are made to CPU performance, the total number of cores of highend supercomputers has increased tremendously. Efficient handling of large numbers of cores is a key aspect in the design of supercomputers. Building a supercomputer with lower power consumption and significant reliability is also important from the viewpoints of cost and availability. The K computer [1] is a massively parallel supercomputer system that has over 700k cores, and is designed to achieve a performance of 10 petaFLOPS. In
