Srinidhi Varadarajan
received his Ph.D. in Computer Science from the State University
of New York, Stony Brook in 2000. He presently serves as the Director
of the Terascale Computing Facility at Virginia Tech and as an
Assistant Professor in the Department of Computer Science. Dr.
Varadarajan is the recipient of a CAREER award from the National
Science Foundation, the Egg Factory Technology Innovation award
and a Faculty Fellow award from the College of Engineering, Virginia
Tech.
Dr. Varadarajan's research is focused on transparent fault tolerance
for massively parallel supercomputers, scalable network emulation,
compiler directed strategies for flexible data sharing models
and routing algorithms for backbone IP networks. In the area of
transparent fault tolerance his work concentrates on developing
incremental checkpointing, recovery and migration algorithms.
His research in network emulation is focused on building a distributed
system that can scale to emulate hundreds of thousands of virtual
nodes. This work involves research on several areas, including
compiler directed mechanisms for transparent generation of reentrant
code from non-reentrant sources, automatic checkpointing and recovery,
code migration, dynamic load balancing and 3D environments for
network traffic visualization. In the area of routing algorithms,
he is exploring the use of AI techniques such as reinforced learning
for use in a probabilistic framework for multi-path routing protocols.
Dr. Varadarajan is the architect of System X, the third fastest
supercomputer in the world located at the Terascale Computing
Facility at Virginia Tech.
