To solve this problem, we have developed a binary-level automatic parallelization system that parallelizes binary code via an intermediate representation (LLVM IR) of the LLVM compiler infrastructure. This system requires the generation of parallel code at the LLVM IR level. Therefore, we are developing a parallel code generation function that generates parallel IR code based on directives. However, the performance achieved by this system is not yet clear. In this paper, we evaluate the system using PolyBench/C in order to clarify the execution performance of the code generated by the parallel code generation function of this system. As a result of the evaluation, we confirmed that the IR-level parallelization program generated by the parallel code generation function achieved a higher speed-up rate than the source code-level parallelization program, and that this function has sufficient performance as a parallelization function of the binary-level automatic parallelization system.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システム・アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-08-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2024-ARC-258"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":237607,"updated":"2025-01-19T08:49:40.970319+00:00","links":{}}
