This technology first saves the snapshot of a process's running state, and if an error occurs, restores the snapshot to re-construct the state of the running process and resume the execution. However, Checkpoint/Restart usually restores a saved state to a process executing the same program used by the checkpointed process. Thus the same runtime error may occur in the future, since the bug is not fixed. To resolve this problem, this paper described the design and implementation of a Checkpoint/ Restart system which enables users to restore a snapshot to a process executing a program whose bug has been fixed. We have confirmed that the new system are able to prevents the restored process from suffering from the same runtime error.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアと オペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-07-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2010-OS-115"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"links":{},"id":70082,"updated":"2025-01-21T23:36:45.098378+00:00"}
