2014 IEEE TECHNICAL FIELD AWARDS

IEEE Reynold B. Johnson Information Storage Systems Award
Sponsored by Hitachi Data Systems

John K. Ousterhout and Mendel Rosenblum

For fundamental contributions to the design and implementation of log-structured
file and storage systems

John K. Ousterhout and Mendel Rosenblum are computer
scientists who introduced a radically different approach to file
system design with their log-structured file system (LFS), first
presented in 1992. LFS treats disks more like a tape drives, appending all new data sequentially rather than making random
accesses, and it has provided a more efficient and cost-effective
data storage process to meet the demands of larger memory devices. Before LFS, file systems assigned each block of data a specific location on the disk; when the data was modified, the new
value was stored in the same place as the old. Log-structured
file systems use a different approach, where all new information

is written sequentially to disk, like a log; if a block is overwritten, the new contents are assigned a new location on disk at the
head of the log. This improved write speed as much as 10x by
avoiding expensive disk-head movement, and also enabled faster
recovery from computer crashes. The work of Drs. Ousterhout
and Rosenblum has influenced storage systems at all levels, from
remapping layers on magnetic disks, to flash translation layers, to
large-scale datacenter storage systems.

Jon Crowcroft

Robert D. Lorenz

For contributions to research in and
teaching of Internet protocols, including
multicast, transport, quality of service,
security, mobility, and opportunistic
networking

For contributions to the development of
methodologies and sensors for precision control of electric motor drives and
coordinated drive systems

Jon Crowcroft has been one of the most influential forces on the
growth of the Internet.With early contributions to transport protocols (TCPs) for reliably sending data from one network device to another and TCP congestion-avoidance techniques, Dr.
Crowcroft is best known for his work during the late 1980s on
Internet protocol (IP) multicast. IP multicast enables sending data
to multiple interested receivers with a single transmission, and his
ideas have become the centerpiece for modern multicast routing.
He has also been a champion of opportunistic networks, which
provide a more flexible means of connectivity for remote/rural
areas, where information is transferred using a combination of
remote and fixed networking nodes compared to traditional fixed
network infrastructures.
An IEEE Fellow, Dr. Crowcroft is the Marconi Professor of
Communications Systems at the University of Cambridge, U.K.

Robert D. Lorenz's pioneering development of self-sensing
motor drives has provided one of the most important concepts
in advanced machine control. Prof. Lorenz is considered the
leading expert in self-sensing machines methods, where the
sensing functions are fully integrated on a drive to detect key
operating characteristics including rotor position, torque, speed,
temperature, and motor/load diagnostics. Avoiding the need for
conventional position sensors reduces cost and increases motor
efficiency. His "electronic line shaft" control methodology coordinates multiple drives along a manufacturing line to act as if
they were directly coupled by a shaft. This has been invaluable
to the paper and printing industries, where web rolls are sensitive to even minor differences in speed among motor drives.
An IEEE Fellow, Dr. Lorenz is a professor of mechanical engineering and Co-Director of WEMPEC at the University of
Wisconsin, Madison.
