AbstractAbstract
[en] The accelerator control system of the J-PARC MR started operation in 2008. Most of the components of the control computers, such as servers, disks, operation terminals, front-end computers and software, which were introduced during the construction phase, have went through one or two generational changes in the last 15 years. Alongside, the policies for the operation of control computers has changed. This paper reviews the renewal of those components and discusses the philosophy behind the configuration and operational policy. It is also discussed the approach to matters that did not exist at the beginning of the project, such as virtualization or cyber security. (author)

J-PARC MRの加速器制御システムは、2008年に運用を開始した。建設期に導入された、サーバ・ディスク・運転用端末・フロントエンド計算機・ソフトウェアといった制御計算機の構成要素のほとんどは、この15年で1～2回の世代交代を経ている。それに伴い、これらの運用方針も変化した。本稿では、各コンポーネントの機種更新を振り返り、構成や運用方針の背景にある思想を検討する。また、建設期には無かった、仮想化・サイバーセキュリティといった考え方への対応についても議論する。(著者)Original Title
