Using MatlabMPI, you can construct efficient programs with relatively easily. However, MatlabMPI has an obvious disadvantage of low performance communication via file-I/O. In this article, we show the design and implementation of a MatlabMPI-to-MPI translator to provide a good programming environment for parallel computing. This improvement of parallel execution speed of translated codes is obtained mainly by the replacement of communication routines. Our translator receives a MatlabMPI M-file script as an input and outputs a C program parallelized with MPI. Experimental results show that translated matrix-matrix multiplicaton programs with this system can run about twice as fast as the original code with MatlabMPI. This confirms the effectiveness of our approach to construct a parallel programming environment to maintain readability, describability, and performance.","subitem_description_type":"Abstract"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_3_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.ipsj.or.jp/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_3_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意：本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。 "},{"subitem_rights":"The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
