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).
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.

*** IEEE MDM 2023: Call for Workshop Proposals ***
Several workshops will be held together with the IEEE MDM 2023 conference.
Workshops are planned to take place on July 3, 2023, the day before the
main conference, each of them running anywhere between half a day and a
The logistics of the workshops will be handled by the MDM 2023
organization. Specifically, MDM 2023 will take care of facilities,
catering, and the registration process pertinent to all hosted workshops.
The organizers of accepted workshops are required to announce the workshop
and call for papers, solicit submissions, invite and coordinate with PC
members to ensure that controversial submissions are resolved, and decide
upon the final workshop program that must be published at least two weeks
before the early registration deadline. The submission deadline of the
workshops must be set 1-2 weeks after the notification date of the main
conference. In addition, each workshop must collaborate with the
Proceedings Chair for the purpose of ensuring timely completion of the
camera-ready copies before April 28, 2023 (TBC), when official conference
proceedings are due. A workshop paper is allowed up to 6 proceedings pages.
Publication of call-for-papers and participation as well as eventual
workshop reports in various outlets are encouraged.
Proposal evaluation criteria include the following: relevance to MDM,
scientific quality, perceived interest and past performance (e.g., previous
submission counts and/or workshop participants), and overlap with other
The deadline for the receipt of proposals to be co-located with MDM 2023
is: December 9, 2022.
Notification of acceptance will occur by: December 23, 2022.
Proposals need to include the following:
Title and Acronym for the workshop.
Concise description of the workshop scope/theme along with a (tentative)
list of topics.
Names and contact info of the organizers.
Preliminary list of (potential) PC members.
Important milestones for the workshop (e.g., announcements, submission).
Proposed duration (half-day or full-day workshop).
Bio-sketches of the organizers.
If the organizers have had such/similar workshops held in the past, a
Past performance (if applicable), e.g., previous submission counts and
Please submit the workshop proposals as a PDF attachment to both the
following email addresses: kyriakos(a)smu.edu.sg, yasumoto(a)is.naist.jp. A
verification response will be returned for each submission.
