Title: Optimization of communications on Large scale parallel computers
Speaker: Yoshiyuki Morie (System Software Research Team)
Presentation Language: Japanese
Presentation Material: English
In the recently, the scale of supercomputer has been increasing remarkably. This trend will have been going from now. On the other hand, in network, multiple communication devices are installed and fat-tree, mesh/torus as network topology are adopted. There are several problems to be solved for adopting these. One is the efficient utilization of multiple communication devices. Another one is shortening communication delay by reducing the number of hops or contentions on a such network topology. We will introduce the optimization of communication for these problems.
