                            Stu Zweben, Former CSE Chair, Retires
                      Stu Zweben was born in the Bronx. He studied mathematics as an undergraduate at City
                      College of New York, graduating with his BS degree in 1968. At this time, there were few
                      graduate programs in computer science (in fact, 1968 is generally considered founding year of the
                      OSU Computer Science Department). Stu chose to study computer science at arguably the first
                      such program, at Purdue University, which was only a few years old at the time. He received a
                      joint MS in statistics and computer science in 1971 and completed his PhD in computer science
                      in 1974. He then joined OSU as an assistant professor of Computer and Information Science and
                      has remained on the OSU faculty ever since.

                        Stu’s early work on software engineering dealt with software quality metrics. He also contribut-
ed to the literature in data structures and algorithms, and later expanded his research focus to include software testing,
formal methods in component-based software reuse, computer science education and computing work-force matters.
His election as an ACM Fellow in the late 1990s recognized his achievements in research as well as his outstanding
service to ACM. Stu advised several PhD graduates who have gone on to leadership positions, such as department
chair and research center director. With his eclectic interests, he also co-advised theses with faculty in the Industrial
and Systems Engineering Department and the History Department at OSU. He served on the editorial board of IEEE
Transactions on Software Engineering from 1990-1998 and remains on the editorial board of Empirical Software
Engineering Journal.

Stu chaired the CSE Department from 1994-2005, guiding the department through the large enrollment swings
resulting from the dot-com boom and crash periods. During Stu’s term as chair, the department’s research
productivity grew more than four-fold, and Stu hired more than a dozen faculty members who went on to win NSF
CAREER awards while at OSU. Almost all of them still are on the CSE faculty.

Though Stu is best known within OSU for being a very successful department chair and, following that, as Associate
Dean for Academic Affairs and Administration in the College of Engineering, he has held many other leadership posi-
tions in computing professional societies. He was elected ACM president and served from 1994-1996, after serving as
vice-president from 1992-1994. He recently completed a term as chair of the ABET Computing Accreditation Com-
mission and currently serves as chair of ABET’s Accreditation Council. As a representative to the Computing Research
Association, he took over, and continues to conduct, the annual Taulbee Survey. This critical instrument is widely used
to gauge enrollment, employment and salary trends in academic computing. His research contributions and leadership
in the computing profession have made him a popular speaker; he has given over 100 invited talks all over the world.

Stu’s many honors and awards include election as an ACM Fellow and ABET Fellow. He also received an Outstanding
Contribution to ACM award (1997) as
well as a CRA Special Service award
(2006), and was recognized as Technical         INSIDE                         Focus on Research 4

 Message from the Department Chairperson

                        Dear CSE Alumni, Parents, Friends and Colleagues,

                        We are welcoming many new students in the beginning of the 2009 academic year. Under the
                        increasingly more selective admission policies, we have observed steady increase in undergradu-
                        ate enrollment since 2005, and significant increases of graduate enrollment since 2007. We
                        also welcome two new assistant professors, Luis Rademacher and Chris Stewart. Luis received
                        his PhD from MIT, focusing on algorithms and theory. Chris received his PhD from University
                        Rochester and his research area is in computer systems.

                        Stu Zweben officially retired in July this year. Stu was the department chair in a long term of
                        11 years (1994-2005), and made significant contributions to the department and to the univer-
                        sity. The department will honor Stu in the awards banquet next spring. To celebrate Professor
                        B. Chandrasekaran for his 40 years service in the department and scientific contributions in the
                        field of artificial intelligence, the department, his former students, colleagues and friends have
set up a graduate fellowship under his name. We have continuously received contributions to the fund since it was estab-
lished a few months ago.

In June 22, 2009, the department was saddened to learn of the passing of our colleague Eitan Gurari (1947-2009).
Trained as a computer science theoretician, Eitan developed and maintained several open source software packages,
including TeX4ht that has been widely used in the scientific community for publishing research papers on the Internet
by translating LaTeX into the html format.

We have added another distinguished alum to the CSE Advisory Committee: Michael Fortin of Microsoft. In this issue,
we feature three alums who have distinguished themselves in three different fields: Michael Fortin in operating systems,
Jai Menon in databases and CSE Professor Rick Parent in graphics.

The department has continued to maintain its high momentum of research. In the last three months, the CSE faculty
received 14 grants from the National Science Foundation. I hope you enjoy reading this issue of the newsletter, and
keep us informed about your new progress. I look forward to communicating with you again in the next issue of the
Buckeye Blog with many exciting new stories.

 Mike Fortin: Microsoft Distinguished Engineer
                   David Ogle is Named IBM Distinguished Engineer
                           Mike Fortin graduated in 1991 with a PhD in the area of operating systems perfor-
                           mance. His research, dissertation and projects were influenced greatly by his advisor
                           Douglas Kerr, the department chair Mervin Muller, and a number of professional
                           performance analysts from HP’s Fort Collins HP-UX team. He considers the lessons
                           learned at Ohio State and from the above individuals to be foundational; many of the
                           successes he has been a part of since leaving the Buckeye State were rooted in skills
                           and perspectives developed in Columbus.

                           After graduation, he accepted a position in IBM Austin to work on the AIX Per-
                           formance team. He really felt that AIX was going to be the UNIX to shine in the
                           years ahead. With the full support of IBM, he figured the AIX team would have the
                           hardware and software resources necessary to complete and ultimately become the
                           dominate player just as they had done in other markets. He started in the performance
                           group as a developer and analyst but eventually transitioned to being more of an
                           architect on new OS projects. “New OS projects, boy there were many! All totaled, I
worked on 6 distinct operating systems in the 5+ years I spent in Austin. Thought AIX is still alive and thriv-
ing today, IBM in the mid 90’s was repeatedly looking for new OS platform paradigms to replace AIX, the other
UNIX offerings and to supplant Windows as well.”

“With so much Operating Systems architectures on which to focus, my IBM years turned out to be outstanding
from learning and experience standpoints.” Many of the key architectural tradeoffs separating industry’s and
research’s competing OS designs were being put to the test constantly and performance was often a key arbiter
in shaping or tossing out feature designs as well as entire products. It is during these years that many key OSU
lessons helped him grow and succeed.

At Ohio State, he had become quite familiar with how difficult it was to convince people of alternate designs
without having experimental data or prototypes. As a result, he learned to ask himself “what would it take
to convince a skeptic” questions and that helped shape what he worked on and when he presented conclusions.
“This simple thing has served me quite well. I’m constantly advising people that the most important thing they
do is to decide “what” to work on, and then “how” to do that work.”

Though his IBM years were awesome learning years, product successes were few and far between. He began
to realize he was working on the wrong thing. Realizing a need to change the “what” part of his work, Mike
decided to see what the other end of the marketplace looked like and moved to Redmond, WA to join Micro-
soft’s up and coming NT Operating System team in 1997. Microsoft, as it turns out, was looking to improve the
security, performance reliability and scalability of its Windows codebase by moving to a newer and more modern
core OS design, while still providing the compatibility and familiarity of the existing Windows 95 family. The
bulk of his career at Microsoft has been focused on performance, reliability, scalability and compatibility, and
he is now shifting to include security as an area of focus. Ironically, many of the key challenges IBM looked to
overcome with alternate designs were more successfully realized in the newer OS code base at Microsoft. As a
result, roughly 1 billion Windows-based computers are in use across the globe today.

At Microsoft today, Mike is a Distinguished Engineer in the Windows division, serves as the Multi-Core Cham-
pion for Microsoft, and is the Director of Development for the Reliability, Security, Performance, Telemetry, Li-
censing & Deployment, and Ecosystem Fundamentals teams. He has been working with Ohio State alum, Wael
Bahaa El-Din since 1997.

“Of all the things I’m grateful to Ohio State for, the opportunity to meet my wife Marta easily the most signifi-
cant. We met in the fall of 1985 and have been together ever since. Marta, our four daughters, and our extended
family all make Redmond, WA our home today.”

Jai Menon: IBM Vice-President of Technical Strategy

                             Jai Menon is responsible for shaping IBM’s technical strategy and identifying emerging
                             technologies critical to the future of IBM as Vice-President of Technical Strategy. In
                             addition, Jai serves as the global Vice-President of IBM’s University Collaboration pro-
                             grams, serves on several university industry advisory boards and works with academia
                             to establish innovative research and build 21st century skills in support of the innova-
                             tion economy.

                               Jai received a Bachelor of Technology in Electrical Engineering from the Indian Insti-
                               tute of Technology in 1977 and earned MS and PhD degrees in Computer Science from
                               Ohio State University in 1978 and 1981. OSU was Jai’s first home in the US and “it will
                               always have a special place in my heart for making me feel at home in my adopted land.”
                               It is also where he learned to enjoy football, a game he enjoys watching to this day. In
                               2004, he was delighted to be able to bring his then 12 year old son Vijay to watch OSU’s
                               first football game of the season at Buckeye Stadium – which OSU won of course! Jai
                               continues to stay in touch with people he met at OSU in his 4 years on campus. He often
has lunch with his PhD advisor Professor David K. Hsiao, who now lives a retired life in Mountain View, California.
He continues to meet with a classmate of his from those days, now Director of Computer Science at University of
Waterloo, Professor Tamer Ozsu, and he is Facebook friends with Marty Marlatt, until recently a CSE administrator
and one of the first people to befriend him on campus!

Jai began his career with IBM Research in 1982 and became IBM Research’s leading authority on the design and
architecture of data storage systems which enable enterprises to manage their data reliably and efficiently. He is
well-known as an industry pioneer and technical visionary in RAID Research and is one of the key early contributors
to the technology behind what is now a $20B industry. He directed IBM’s world-wide research in Storage Systems
and his leadership helped establish IBM Almaden as a world-class center of competence in storage research. He
became Director of the Storage Systems Institute whose goal was to speed the incorporation of scientific and techno-
logical advances into IBM storage system products. In 2003, Jai joined the Systems Division as CTO and, later, VP of
Systems Strategy and Architecture, where he was responsible for setting the strategy and direction of IBM’s systems
software products and guiding the development of 6000 software developers.

In 2001, Jai became an IBM Fellow, the highest technical position within IBM. He is one of only about 10 people
in IBM – a company of 370,000 people – to have achieved the highest technical honor of IBM Fellow and to also be
a Vice-President. Over the course of his career, Jai has been awarded 52 U.S. Patents and has been the recipient of
many IBM technical awards and external honors. He is an IEEE Fellow and an IBM Master Inventor. In 2002, he
received the IEEE Wallace McDowell Award. In 2004 he received the Distinguished Alumnus Award from the Col-
lege of Engineering at Ohio State. In 2006, he became a Distinguished Alumnus of IIT, Madras and he also received
the IEEE Reynold B. Johnson Information Systems Award. Jai is the author of 31 papers and 47 technical reports and
he is a contributing author to three books on database and storage systems.

In the last few years, Jai has begun to reconnect with OSU. In 2007, he returned to give a talk as part of the Dean’s
Lecture Series. In his role overseeing awards from IBM to universities, there have been several IBM Faculty Awards
and Shared University Research Awards presented to Ohio State professors, and several PhD Fellowship awards
given to OSU students. Every year, IBM hires several students from Ohio State, and there are currently more than
400 IBMers who are Ohio State alumni, 26 of whom are IBM executives.

‘I am very grateful for what I learned at OSU and I am always proud to say I am a Buckeye. Last year, 3 of IBM’s 60
IBM Fellows were OSU alumni, which is more than any other university can claim – a real testament to the kind of
talent OSU produces! I am looking forward to my new role on the CSE advisory committee and I am looking forward
to driving the OSU-IBM partnership to the next level.”

                          customers. According to IBM, a Distinguished Engineer is a key technical consultant with
                          a deep area of expertise or across multiple areas. He or she is a strategist, shaping business
                          decisions and processes. They also provide leadership for technical disciplines, competen-
cies and professions, and develop architectures, standards and tools.

After graduating from Ohio State, Dave headed to North Carolina to work for IBM. He intended to stay there for
3-5 years, but liked it so much that has has been there for almost 20 years. He says IBM has given him the oppor-
tunity to grow his skills and respond to new challenges. He is currently the Chief Test Architect for the Lotus
branded software. On a personal note, Dave very much enjoys North Carolina. There he met his beautiful wife and
they are busily trying to raise their three second grade boys.

                                 pool” (or buffer cache), to avoid the long delays that would occur if slower hard disks
had to be used. Such caching mechanisms have been widely used in almost all memory-capable digital systems, from
large computer and database systems to small devices such as cell phones.

In a search engine, such as Google, all kinds of Web pages from the Internet are timely retrieved and partially stored
in a huge MySQL database. The majority of Web page data items are archived in massive hard disk storage, and only
the most frequently accessed pages are expected to store in buffer pools in DRAM memory. For each user’s search in
Google, if the query hits in the buffer pool, the user would quickly get the search results; otherwise, the results would
have to be fetched from slow disk storages, causing long delays.

Since the buffer pool space is very limited, data blocks are frequently replaced by newcomers. A critical task of cache
management is to keep the most frequently used data in the buffer pool (or to hold the frequently accessed Web pages in
a search engine). A data block replacement algorithm decides which block will be evicted when a new data block needs
to be allocated in the buffer pool. The database access speed is mainly determined by the accuracy and efficiency of the
replacement algorithm.

The commonly used LRU, or Least Recent Used, algorithm (such as in operating systems, databases and many other
digital devices) evicts the least recently used data block. But since a data block that was least recently used is not always
the same as the most infrequently used data block, two serious problems arise: (1) one-time accessed data blocks that
were recently used can easily kick out frequently used data in the cache; and (2) a high rate of misses occurs for
loop-like data accesses due to limited cache sizes. Zhang and Jiang’s development, the LIRS (Low Inter-Reference
Recency Set) caching algorithm, can effectively detect the one-time, or most infrequently, used data blocks and evict
them as early as possible and can adapt the loop access patterns in replacement decisions. Another advantage of LIRS
is its simple implementation in any system. Zhang and Jiang’s work serves as a critical component in the MySQL buffer
pool management now. In fact, in MySQL’s most recent version 5.1 (released in November 2008), LIRS is called the
“Jiang-Zhang LIRS Caching Algorithm.”

Relative to this work, Zhang has been elected to a Fellow of the Institute of Electrical and Electronics Engineers for
his contributions to computer memory systems. The original research and paper were supported by National Science
Foundation grants to Zhang. The student, Jiang, is now an assistant professor in the Department of Electrical and
Computer Engineering at Wayne State University. NSF continues to support his research with grants including a
CAREER award. Since the LIRS algorithm was published in the 2002 ACM SIGMETRICS Conference, it had been
widely tested and evaluated by both academia researchers and industry developers. Before this database application,
LIRS was adopted first in computer systems, such as Linux and NetBSD, the two widely used open source operating
systems for laptops, servers, supercomputers and network systems.

                 CSE Welcomes New Faculty
                                                          Chris Stewart
                   Assistant Professor Chris Stewart received his PhD from the University of Rochester, where he
                   focused on systems support for the Internet services that power much of today’s digital economy
                   and society. His research devised new analytic models to understand the complex behaviors of
                   these systems. One particularly important discovery found that the request mix of real-world
                   Internet services is nonstationary. At an e-commerce site like Walmart.com, this means that the
                   relative proportions of user requests for searching for items vs. buying products vs. locating stores
                   changes frequently over short and long durations. This discovery upset stationary models of user
                   access patterns that were, before Chris’ findings, the standard in research. Developments from
                   this finding include a publicly available benchmark that is now used by many research teams and
                   a prototype management system that was transferred to an HP product team. During his time in
Rochester, Chris authored or co-authored more than a dozen peer-reviewed publications at prestigious conferences like
NSDI, USENIX, EuroSys, SIGMETRICS and ASPLOS. He also has four pending patents from collaborations with
colleagues at HP Labs.

At Ohio State, Chris plans to study emerging challenges in the evolution of computer systems, including energy man-
agement and data-intensive applications. He is especially interested in the development of sustainable datacenters, i.e.,
large computing facilities that can operate profitably with a zero-carbon footprint. His most recent paper on integrat-
ing renewable energy into datacenter management will be presented at the HotPower workshop in October.

On the personal side, Chris is also a proud ``hip-hop head’’ (a fan of rap music). Before starting graduate school,he
wrote lyrics for local rappers from the Bay Area. Today, he only writes research papers, but his hip-hop background
still influences his writing. While describing the challenge of managing an Internet service using a limited amount
of available data, Chris was reminded of the Digital Underground verse, ``tryin’ to make a dollar out of 15 cents.’’ A
shortened version of this verse became the title of his USENIX 2008 paper.

                                                       Luis Rademacher
                   Assistant Professor Luis Rademacher grew up in Santiago, Chile. He became a mathematical
                   engineer at University of Chile in 2002 and received his PhD in Mathematics from the
                   Massachusetts Institute of Technology in 2007. After receiving his PhD, he spent two years as a
                   postdoctoral researcher at the College of Computing at the Georgia Institute of Technology. His
                   main area of research is theoretical computer science, in particular, the computational complex-
                   ity of geometric problems and understanding the power of randomization as an algorithmic and
                   mathematical tool. One of his main results lead to a nearly optimal algorithm for approximate
                   Principal Component Analysis, a fundamental tool in applied statistics.

                     He has co-authored over 7 research papers and received the Johnson prize in 2007 from MIT’s
mathematics department. At Ohio State University his work will focus on exploiting randomization and convexity in
the design of efficient algorithms, and applications to optimization and network routing.

Apart from mathematics and theory of computing, in his spare time he deeply enjoys music, especially classical.

           In Memoriam Eitan Gurari 1947 - 2009
                  It is with immense regret CSE must announce the passing of a member of our professional family. Eitan
                  Gurari, Associate Professor, passed away Monday, June 22, 2009. This was a sudden and unexpected death
                  leaving us all stunned and saddened.

             Eitan was born in Israel in March 1947. He attended Technion - Israel Institute of Technology where, in
             1971, he received Bachelor’s of Science in Physics. He continued his studies there, but changed focus to
             Computer Science receiving a Master’s degree in 1974. The University of Minnesota granted him a PhD
             in 1978 in Computer Science after which he taught at the University of Wisconsin - Milwaukee and the
             State University of New York at Buffalo. He joined the Ohio State University Department of Computer
Science and Engineering in 1982.

Eitan started his career as a theoretician. He made fundamental contributions to automata and complexity theory. His
textbook, An Introduction to the Theory of Computation, was highly praised and he published frequently in JACM, SIAM
Computing, ACM STOC and IEEE FOCS. After joining OSU, Gurari switched his research focus, starting to build
software systems. His most recent software engineering research interests covered hypertext processing and Braille
production. His creation, the TeX4ht system, has been widely used in the scientific community for publishing research
papers on the Internet and is generally considered to be the best application to translate LaTeX into other formats. He
often received emails from users praising and appreciating the various software systems he had single-handedly built.

Eitan leaves behind his wife, Shaula Gurari, two sons and three daughters. Eitan was a dedicated researcher and
respected colleague. This is a deep loss to CSE and we extend our most heart-felt condolences to his family in their loss.
