The current interpreter is a bytecode-based Virtual Machine (VM). However, the current VM does not support parallel processing because the VM is restricted to running at most one Ruby thread at time. Parallel processing using multiple processes requires additional overhead to transfer objects over some inter-process communication mechanism. Based on these challenges, we are developing a Multiple Virtual Machine (MVM) implementation which can run multiple Ruby VMs simultaneously in one process. Each individual VM manages an isolated object space. For MVM, we implemented a fast object transfer technique by taking advantage of sharing the same virtual address space. We also designed a programming interface (API) to use these features. Moreover, we extended dRuby, a remote method invocation framework, to make it easy for programmers to use MVM features. In order to keep compatibility with the current Ruby interpreter, we implemented MVM by replacing the current VM's use of process-global resources, such as C global variables and I/O resources, with the use of VM-local data structures. In this paper, we will describe the design and implementation of our MVM and its API. We will also show several performance evaluations of parallel processing in Ruby using our current MVM implementation.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"42","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"25","bibliographicIssueDates":{"bibliographicIssueDate":"2012-03-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"5"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:35:46.056668+00:00","id":81614,"links":{}}
