However, we can not extract parallelism among iterations for the loop which has complex loop-carried dependences. In addition, iteration-based parallel execution is not suitable to the computer cluster environment because of task granularity. In this paper, we propose the incremental processing for parallel execution of loops. In the incremental processing, plural loops which access same array data are executed in parallel with the pipeline method. We can apply incremental processing to loops with complex loop-carried dependences since incremental processing makes full use of parallelism among loops and iterations in loops are executed sequentially. Furthermore, loops are executed in parallel by means of overlap between computation and communication, which reduces communication overhead among tasks. For incremental processing, analysis of the access order on array elements in the loop is very important. We introduce the access pattern which defines the access order in loops, and develop the algorithm for analyzing the similarity of access patterns. We also examine the effectivity of our algorithm for parallel execution of loops with shared arrays.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/10316"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会","subitem_publisher_language":"ja"}]},"item_10_rights_12":{"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。 Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
