Projects
Research Assistant - Fermi National Accelerator Laboratory
Currently, I am working with the DZero Grid Experiment at the Fermi National Accelerator Laboratory,IL.  My work involves development and testing of Information Services modules to be built inside JIM - Job  Management and Information Service, is an intergral part of the Data Handling System called SAM. SAM provides transparent delivering of files and managing of caches of data on distributed computing environments. I have developed Python API on top of XMLRPC library to interface Xindice native XML database to this project. My current activities involves delivering a Grid Web Portal  solution to manage jobs submitted  from different parts of the world and to develop tools built on top of GSI (Grid Security Infrastructure) model.

Thesis
This thesis describes an enhanced ThreadManTM Thread Manager, a user-level thread manager with a standard API and library. It has been designed for automatically managing and scheduling parallel software on contemporary symmetric multiprocessing  (SMP's) machines, across various system architectures and operating systems and is intended to be accessed by multi-threaded source code generated by PARSATM Software Development Environment. ThreadMan also provides constructs for parallel control, synchronization and portability.
 
Two types of multithreaded projects are supported - stand alone applications  and functions are supported.  Sequential and parallel versions of two projects have been developed, compiled on three different systems with diverse native  threading mechanism and their performances are compared to demonstrate i.)ThreadMan can efficiently manage the execution of applications that contains numerous form of parallelism. ii.)ThreadMan can manage the parallel software on a single processor system with virtually no degradation in performance when compared to sequential code and automatically scalability is achieved when executed on multiprocessor machines. iii.)portability.
