| Outline of Final Research Achievements |
Parallel computer systems, which are composed of multiple high-performance computers, are used in various fields. In developing applications for such systems, different programming languages are used depending on the architecture. Therefore, the portability of code between systems has become an issue.
In this research, we have designed a new parallel programming language to reduce the cost of code porting. Specifically, we designed directives and metaprogramming that can bring out the performance of parallel computer systems. We showed that source code written in a single programming language can be used to develop applications that run at high speed on a variety of systems.

| Academic Significance and Societal Importance of the Research Achievements |
将来の並列計算機システムでは、現在よりも複雑化・多様化すると考えられる。本研究成果を用いることで、そのようなシステムにおいても高速に動作するアプリケーションを簡易に開発できるため、コードの移植や性能チューニングに要するコストを大幅に削減することが期待できる。
