RESEARCH
[Dec 2004 -
Present] Research Assistant for Dr.Mahinthakumar.
Interests: High
Performance Computing, Bio-inspired optimization algorithms, Performance
Analysis and Optimization.
Designing a scalable
framework for parallel bio-inspired optimization algorithms.
Parallelization
of water quality simulation code (EPANET) and subsequent porting to Blue
Gene/P and Cray XT4.
Grid enabled
workflow for efficient execution of water quality simulations and
deployment on large scale distributed systems like Teragrid and SURAgrid.
Project: Performance
Engineering Research Institute (DOE SciDAC project)
Performance Analysis and Optimization of Scientific applications on some
of the fastest supercomputers in the world (esp. IBM BlueGene/P & Cray
XT4/5 supercomputers). Achieved an improvement of 18.77% for a Groundwater
application (PFLOTRAN) over baseline results on 4096 cores of Cray XT4.
Previous
Project: Performance
Evaluation Research Center (DOE SciDAC project)
Analyzing performance of High Performance Computing Applications (Nuclear
Fusion & Astrophysics codes) including performance tool evaluation at
several Supercomputing facilities (Oak Ridge National Laboratory, Teragrid
etc.)
Research group
cluster planning, deployment, benchmarking and maintenance. Analyzed and
optimized the performance of High Performance Linpack (HPL) benchmark on
x86-64 cluster.
GRADUATE COURSEWORK
Parallel Computing, Operating Systems,
High Performance Computer Modeling, Evolutionary Computation, Design and
Analysis of Algorithms, Compiler Construction, Introduction to Numerical
Methods, Inverse Methods, Information Systems Security, E-Commerce
Practicum, Software Engineering, Advanced Water Resources and Neurobiology.
(Worked on
supercomputers/clusters with above architectures and programming
environments).
COURSE PROJECTS
Web Server Audit
Subsystem with McAfee Research: This project focused on augmenting a Web
Server with Audit capabilities compatible with an audit-enabled operating
system (SunOS) and then demonstrates that analysis of attacks on the web
server is improved with the addition of server-specific audit data. This
project is done in conjunction with McAfee Research.
Distributed File
System: A user level distributed file system was developed which also
provided Security, Fault Tolerance, Replication and Availability.
Micro-Shell: A micro shell is
developed that provided a core subset of the features available in the
c-shell.
Datamation Sort:
This
project involved sorting of one million records (size of each record is
100 bytes) and was based on the sort benchmark from Microsoft Research.
Minute Sort: This project
involved sorting the maximum number of records (each record is 100 bytes)
in one minute. (based on Microsoft Research sort benchmark).
Beowulf Cluster (Senior Design
Project): A Beowulf Cluster comprising of 8 nodes was setup and various
parallel programs were implemented.
Operating
Systems Security: A survey was conducted on the security and
protection mechanisms that are present in the modern operating systems.
Secure Routing
in Ad hoc Networks: A survey is conducted on the state of security
in routing algorithms in Adhoc networks.
