Orderreplay, a technique to solve this problem, is widely used because of its small overhead. It has, however, several serious drawbacks: all processes of the parallel program have to participate in replay even when some of them are clearly not involved with the bug; and the programmer cannot stop the process being debugged at an arbitrary point. We adopt another method for deterministric replay, data-replay, which logs contents of the events rather than their order, and makes it possible to run and stop each process independently. Data-replay is well able to cooperate with checkpointing/rollback mechanism. We applied the data-replay mechanism to MPI based parallel programs. The result of our experiment with Nas Parallel Benchmarks shows that our mechanism works at a practical cost. Logging communicated data incurs only 24% overhead while it accelerates replayed execution by 38% both in average.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"224","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"214","bibliographicIssueDates":{"bibliographicIssueDate":"2005-08-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG12(ACS11)","bibliographicVolumeNumber":"46"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T22:47:47.220951+00:00","created":"2025-01-18T22:51:08.229876+00:00","links":{}}
