[dbjapan] Prof. Willy Zwaenepoel 講演『Software for Fast Storage Hardware』

日本データベース学会の皆様、首藤です。 分散システムやストレージの分野で影響の大きいお仕事を数多くされてきた Willy Zwaenepoel 氏（シドニー大 工学部長）の御講演を、 オンラインおよび京都大学で催します。 分散共有メモリ TreadMarks や Nutanix 社をご存知の方は多いと思います。 タイトル：『Software for Fast Storage Hardware』 話者：Prof. Willy Zwaenepoel, Dean of Engineering, University of Sydney 場所：オンライン（Zoom）、および、京都大学 学術情報メディアセンター南館 202号室 　　　（京大関係者以外が会場にいらっしゃる場合、首藤まで御一報下さい。） 日時：2022年 11月 30日(水) 13:15 ～ 14:15 オンライン参加の事前登録： https://kyoto-u-edu.zoom.us/meeting/register/tZwkdOyrrT8rEtKMYsBB90lhOeK_j3… （登録すると Zoom URL が返送されます。） 概要： Storage technologies have entered the market with performance vastly superior to conventional storage devices. This technology shift requires a complete rethinking of the software storage stack. In this talk I will give two examples of our work with Optane-based solid-state (block) devices that illustrate the need for and the benefit of a wholesale redesign. First, I will describe the KVell key-value (KV) store. The key observation underlying KVell is that conventional KV software on fast devices is bottlenecked by the CPU rather than by the device. KVell therefore focuses on minimizing CPU intervention. Second, I will describe the KVell+ OLTP/OLAP system built on top of KVell. The key underlying observation here is that these storage devices have become so fast that the conventional implementation of snapshot isolation – maintaining multiple versions – leads to intolerable space amplification. Kvell+ therefore processes versions as they are created. This talk describes joint work with Oana Balmau (McGill University), Karan Gupta (Nutanix) and Baptiste Lepers (University of Neuchatel). 経歴： Willy Zwaenepoel received his BS from Ghent University in 1979, and his MS and PhD from Stanford University, in 1980 and 1984, respectively. He is currently dean of engineering at the University of Sydney. Previously, he has been on the faculty at Rice University and head of the school of computer and communication sciences at EPFL. He has been involved with a number of startups including Nutanix (Nasdaq:NTNX). He was elected IEEE Fellow in 1998, ACM Fellow in 2000 and ATSE Fellow in 2020. He received a number of awards for his teaching and research, including the IEEE Kanai Award, the Eurosys Lifetime Achievement Award, and the IEEE Outstanding Technical Achievement in Distributed Processing Award. His main interests are in operating systems and distributed systems. 首藤 一幸 shudo(a)media.kyoto-u.ac.jp http://www.shudo-lab.org/ 京都大学 学術情報メディアセンター
