Outline of Final Research Achievements

In this study, we extended a computer language Ruby to increase execution performance to establish a new high-productive computer language HPC Ruby. We successfully developed HPC Ruby static compiler and runtime systems. Based on our evaluation, HPC Ruby showed from 50 % to 90% execution performance in numerical programs compared to C language. In order to show feasibility of the use of Ruby in scientific computation, we developed Ruby based software in earth science, astrophysics, and discrete optimization areas.
As for the ultra high-speed distributed computing using 100Gbps internet, we developed 40Gbps single stream TCP system and 100Gbps multi-stream TCP system. We performed very long distance internet experiments using Tokyo, New Orleans (US) and Amsterdam (Europe). Performance results shows we can efficiently utilize more than 90% of available bandwidth in both 40G and 100G environment. This was the world first realization of very long-distance high-speed TCP data-transfer.
