RESEARCH EXPERIENCE

  • May 2004 – present: Research Assistant at Extreme! Lab & Pervasive Technology Lab, Indiana University. Worked on the following projects so far:

o       Worked on NSF Middleware Initiative (NMI) sensors project developing a Common Instrument Middleware Architecture (CIMA) (www.instrument-middleware.org).

Technologies: C/C++, MySQL, gSOAP

o       Contributed to developing a Binary XML for Scientific Computing

o       Developed a C++ Reflection library

Worked on developing a tool to analyze large amounts of logs in different domains in order to aid in problem determination.

Technologies: Java, DB2

Developed a tool for mining BlueGene supercomputer logs which would assist determining job failure patterns. The tool was able to find frequent patterns among 4,000,000 BlueGene log entries.

Technologies: Java, DB2, BlueGene administrative utilities

Supervisors: Amitava Majumdar and Adam Birnbaum

Worked on a simulation of using supercomputing resources accessed over the grid for image guided neuro surgery.

Technologies: Python, Perl, PBS, Loadleveler, MPI
