We are developing a compact embedded cluster (called EMDC), and  a communication method  on it  for a parallel Fock matrix construction program . The parallel Fock matrix construction program was developed on EHPC project, and EMDC has been developing for low power, small space and rapid prototyping. Network architecture (tree-base network) of EMDC conforms to parallel Fock matrix construction program. In order to communicate among the system, we developed a communication library for tree-base network. In evaluations, two parallelizing methods were executed on EMDC.  Specially, the dynamic task distribution method shows high paralellization efficiency on hetero cluster like EMDC 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":"情報処理学会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":"2007-03-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"17(2007-HPC-109)","bibliographicVolumeNumber":"2007"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":28811,"updated":"2025-01-22T17:52:26.132148+00:00","links":{},"created":"2025-01-18T22:58:49.627954+00:00"}
