In this paper, we propose a new characteristic of sparse matrices about spatial locality of row-index sequences in order to classify suitability for cache memory systems. Moreover, we evaluate proposal characteristic of input matrices and pre-processes (folding). Test matrices are chosen from University of Florida Sparse Matrix Collection. As a result, it is confirmed that there are significant correlations between performance of Sparse Matrix-Vector Product(SpMV) and the general purpose cache (L1) hit rate. Therefore, our characteristic is suitable for auto-tuning pre-processes and memory access mechanisms to avoid application specific optimization in conjunction with matrix size (the number of rows).","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-07-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"17","bibliographicVolumeNumber":"2012-HPC-135"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:36:51.446279+00:00","id":83296,"links":{}}
