Especially, for an economical small or middle scale clusters using accelerators, a programmer must describe accelerator specific APIs to manipulate an accelerator and network programming such as using MPI library. This often becomes an oppressive burden for programmers. Considering them, we propose a novel tool that extends a single node application on a heterogeneous accelerator Cell/B.E. to one for clustered environment with Cell/B.E.. This tool automatically inserts directives, and then converts input source code to one for cluster environment. In the evaluation about source code amount, at most 26% source code is generated by our tool. Besides, we evaluated the performance comparison between a source code generated of our tool and one generated by a programmer. As a result, our tool achieved 76% performance compared with hand-tuned code in Monte-Carlo simulation. On the other hand, in Vector multiplication and Linear Regression, our tool achieved the performance within 3% difference compared with hand-tuned code.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告組込みシステム（EMB）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"30","bibliographicVolumeNumber":"2012-EMB-24"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"links":{},"id":80922,"updated":"2025-01-21T19:35:45.069696+00:00"}
