Software DSM systems using Java language, which is portable on heterogenous systems, are good candidates for such computing environment.  In our previous paper, we proposed a java based software DSM system for clusters.  The system successfully proved its usefulness, but we found some defects including 1) long startup time due to remote invocation of Java VM and 2) troublesome labor to transfer class files on each nodes.  In this paper, we introduce our new Java DSM system, which enables Java VMs to settle on each nodes, reducing startup time.  It automatically transfers application class files and provides access to the client file system.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"85","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"85","bibliographicIssueDates":{"bibliographicIssueDate":"2001-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG07(PRO11)","bibliographicVolumeNumber":"42"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":16869,"updated":"2025-01-22T23:38:26.035135+00:00","links":{},"created":"2025-01-18T22:50:01.288720+00:00"}
