The Gfarm file system is a global file system that federates the local storage of compute nodes among several clusters. It has a scale-out architecture designed to support distributed data-intensive computing. However Gfarm file system does not achieve scalable performance in the case of parallel writes to a single file, a typical file operation in MPI-IO. This paper proposes an optimization technique to improve the parallel write performance to a single file. In the evaluation using BT- IO, IOR and HPIO, MPI-IO/Gfarm achieves scalable parallel I/O performance. Compared with MPI-IO on PVFS2 and NFS, it achieves at most a 1.5x speedup of write performance and 2.0x to 3.0x speedup of read performance using seven storage nodes.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"3250","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"3239","bibliographicIssueDates":{"bibliographicIssueDate":"2011-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"52"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
