MAHADEV SATYANARAYANAN
Satya is an experimental computer scientist who has pioneered research
in distributed systems, mobile computing and
pervasive computing.
Early in his career, Satya was a principal architect and implementor of
the Andrew File System (AFS)
which pioneered the use of scalable file caching, ACL-based security,
and volume-based system administration for enterprise-scale information
sharing. AFS was commercialized by IBM, is in
widespread use today as OpenAFS, and has heavily influenced
the NFS v4
network file system protocol standard. Building on
the AFS work, Satya was a principal architect of the Coda File
System which introduced the concepts of disconnected operation
and
bandwidth-adaptive weakly-connected operation in distributed file
systems. The Coda concepts of hoarding,
reintegration and application-specific conflict resolution
can be found in the hotsync capability of mobile devices today. Key
ideas from Coda were incorporated by Microsoft into the IntelliMirror
component
of Windows 2000 and the Cached
Exchange Mode of Outlook 2003. The Odyssey project
explored the partitioning of responsibility between the operating
system and applications in adapting to wide variability in critical
resources such as wireless network bandwidth and energy in mobile
computing. Through these projects and other projects such as Aura and
Chroma, Satya was a co-inventor of many supporting technologies for
mobile
computing such as such as cyber foraging, data staging,
lookaside caching, translucent caching
and application-aware adaptation. His most recent work in mobile computing has focused on
the role of virtual machine (VM) technology, in the context of the Internet
Suspend/Resume system and the use of cloudlets for
cyber foraging, His most recent work in distributed systems has focused on
deep search of non-text data such as digital photographs and medical
images, in the context of
the Diamond
project,
Satya is the Carnegie Group Professor of Computer
Science at Carnegie Mellon University.
He received the PhD in Computer
Science from Carnegie Mellon, after
Bachelor's and Master's degrees from the Indian Institute of
Technology, Madras. He is a Fellow of the ACM and the IEEE. He was the founding Program Chair of the HotMobile series of workshops, the founding Editor-in-Chief of IEEE
Pervasive Computing, and the
founding director of Intel Research Pittsburgh.
