| Outline of Final Research Achievements |
A big bottleneck in coupled simulations and large scale high performance computing is files I/O. In order to reduct this bottleneck, we have studied and developed a communication scheme of which processes are able to connect each other directly. (1) We have implemented a simple and compact communication library: NSTDIO. The interface of this communication library is designed based on "stdio" of C programing language. This library is enabled to download from GitHub https://github.com/y-morie/nstdio (2) We have developed and implemented a framework of jobs/processes cooperation on inter-site: EGCPOPS. This framework realizes jobs cooperation on inter-site without any administrator authority. This framework is also available from GitHub https://github.com/RyzeVia/exgcoup (3) Because of these framework work well, we have also studied and developed a conceptual design of mechanism for uncertainty: Self-Referential eXecutable: SRX.
