program for a PC cluster which equips GPUs consists of two types of code, for GPUs and for CPUs. The GPU code executes parallelized algorithms to introduce high speed computing supported by a CPU code which performs communication with other nodes. Although MPI library is commonly utilized to transfer data in the CPU code, MPI functions can not be written in the GPU code. Programmers are forced to implement CPU and GPU codes alternately with taking care of data movement among nodes. In order to reduce software development costs, we propose a programming framework called FLAT which enables GPU codes to embed MPI functions. This paper describes execution model and implementation of FLAT, and discusses availability and performance obtained by two case studies, Livermore Loop18 and optical flow programs. Through the experimental results, we confirmed that FLAT increases readability in synthesized GPU codes with maintaining bearable performance degradation, which is less than 3% for a coarse-grained parallel program.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"116","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"105","bibliographicIssueDates":{"bibliographicIssueDate":"2013-10-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"6"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":95765,"updated":"2025-01-21T13:36:33.622000+00:00","links":{},"created":"2025-01-18T23:42:46.413664+00:00"}
