ストリーム指向プログラムのマクロ並列化の研究

【 研究概要 】

ストリーム指向プログラムはGPUといったメニーコアアクセラレータの普及によって、科学技術計算から産業用製品にまで利用されている。その単体性能は、チップ内における密並列によるプログラム実行により高い性能を示す。しかし、複数のアクセラレータを使った超並列計算を考慮すると、タスクの分割と通信タイミングを配慮したプログラム開発が必要になり、性能をスケーラブルに維持したままの開発が困難となる。本研究では、このようなGPUでのストリーム指向プログラムを対容積・対電力での計算能力の高密度化をねらい、自動的に複数のGPUで並列化し、スケーラブルに性能向上が可能なプログラミング基盤技術を開発する。Read More
