Research Overview
Current Research
My ongoing research projects include:
Energy-Efficient Storage Systems
Architecture-level processor fault tolerance
My research is supported by grants from the
National Science Foundation,
Intel,
HP, and Google.
Past Research and Work Experience
I received my PhD in Computer Science and Engineering from
Penn State, where I was a member
of the Computer Systems Lab.
I received my Bachelor of Engineering degree in CSE from the
College of Engineering Guindy, Anna University
in India.
My PhD thesis looked at how to manage power and temperature in storage systems.
I proposed a new disk drive design, called
DRPM,
where the disk can rotate at multiple speeds.
This allows one to dynamically tradeoff power for performance at a finer granularity than
what is possible with just "on/off" states.
Disks with multi-RPM capabilities are commercially available and are
used to build energy-efficient storage systems (e.g.,
Nexsan storage servers).
I also conducted a detailed
roadmap study
of disk drives and showed that temperature will
be a significant roadblock for continued improvements in disk drive performance
and argued that disks should be equipped with dynamic thermal management mechanisms.
Such thermal management mechanisms have
started appearing in
commercial disk drive products.
I have also worked on a variety of other research topics, including:
complete machine power simulation,
energy-conscious query processing in mobile spatial databases, performance and power modeling
of large-scale main-memory systems
(at the
IBM Austin Research Lab)
and lots of interesting things related to transient faults
(at the
Fault-Aware Computing Technology (FACT) Group, Intel).
