The fastest supercomputers today such as Blue Gene/L and XT3 are connected by a 3-dimensional torus/mesh interconnect. Applications running on these machines can benefit from topology-awareness while mapping tasks to processors at runtime. By co-locating communicating tasks on nearby processors, the distance traveled by messages and hence the communication… CONTINUE READING
