| 概要 | In this project, we investigate the usage and the real effect of NBCs in JHPCN resources. In addition to examining existing benchmark programs, we are applying NBCs on several scientific and technical computing algorithms and verifying whether communication hiding improves their performance. The significance of this research is to provide programmers with correct knowledge about the usage and performance characteristics of NBCs and the effect of communication hiding in real applications. This will enable programmers to make correct decisions to actively use NBCs when the effect of communication hiding is expected. |
