In this research, we present SPLiT (Scalable Performance Library Tool) which optimizes resource assignment by predicting processes behaviors. SPLiT collects the performance data in the kernel with PMU (Performance Monitoring Unit) and in processes of applications through the API of its library. With the result of prediction, it assigns CPU cores to each process and improves usage efficiency and caches. We implemented SPLiT on Linux, built its library into Apache and MySQL for the optimization of web applications, and evaluated its performance. The result shows SPLiT can improve the performance up to 26% without the development cost of applying SPLiT lib.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"10","bibliographic_titles":[{"bibliographic_title":"研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-04-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2010-ARC-189"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:28:45.212879+00:00","id":69263,"links":{}}
