Abstract

本研究では,マルチコア・SMT(Simultaneous Multi-Threading) プロセッサ上でのシェルスクリプト実行の有効性を示すことを目的とする.近年マルチコアプロセッサおよびSMTの技術が注目されている.しかし,並列性を考慮していないプログラムを通常のコンパイラでコンパイルしても,マルチコアプロセッサやマルチスレッドを有効活用することはできない.通常,これらの技術の恩恵を受けるためには,並列化プログラミングが必要であり,自動並列化の技術も数多く研究されている.本稿では,シェルスクリプト自身が持つ並列性に着目し,マルチコアプロセッサ・SMT環境において,シェルスクリプトの高速化を実現する手法,シェルスクリプトの自動並列化プログラムを提案する.本提案手法を用いて,マルチコアプロセッサ・SMTマシン上でシェルスクリプトの実行を行った結果,手法適用前に比べて1.4~1.8倍の速度向上を得ることができた.The purpose of this study is to show the effectiveness of shell script execution on multi-core and/or SMT (Simultaneous Multi-Threading) processors. Recently, multi-core processor and SMT technique have become popular even at home and in business. However, using programs or compilers without consideration of parallelism does not give us the benefits of multi-core and multi-thread. Programmers have to do parallel programming to receive the benefits. Therefore, automatic parallelizing technique has been studied actively. This paper proposes automatic parallelizing scheme for shell script programs on multi-core and/or SMT processors. As a result of the experiment, we have confirmed that the speed-up of automatic parallelized shell script program is 1.4 to 1.8 times in comparison with the original shell script program.
