this report, we measured performance of some alternative implementations of communication using Myrinet and a hardware network interface RHiNET-1/NI. To transfer data between the host memory and network interface(NI), there are two alternatives: data write operations by the host processor(PIO) and DMA by the NI. The result of the measurement using Myrinet shows DMA yields better performance except in case the size of the transferred data is very small. User level communication yields a little better performance than communication using system call. This result shows that the overhead of system call is larger than the performance improvement by using host processor. Since processing of RHiNET-1/NI is faster than Myrinet, user level communication will yield much better performance over communication using system calls.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"120","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"115","bibliographicIssueDates":{"bibliographicIssueDate":"1999-03-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"21(1998-ARC-132)","bibliographicVolumeNumber":"1999"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:55:07.628495+00:00","id":23820,"links":{}}
