Darwin's law of the survival of the fittest is theologically outrageous
but it essentially pervades through all phases of life. This has forced
me into making this page as an act of selling of my work and to
exist or rather co-exist in this world where work is the sole
means of valuablitly.
Welcome, employer! My resume in PDF format is
available here.

Recent
Projects
I recently completed the construction of Bheema and Geetanjali. Bheema
and Geetanjali are beowulf clusters targeted towards molecular dynamics
simulations.
Bheema is an 10-node diskless beowulf cluster and Geetanjali is a 16
node disked beowulf cluster. Both these beasts can work several times
faster than their predecessor Kamadhenu. The
exact speedup will be published after some benchmarking.
Here is a link to the documentation
, I am
working on for the construction of Bheema.
I also was working on the enhancement of xmovie, a molecular
dynamics visualization code, written by Dr. Preston B. Moore
from University of Pennysylvania.
The latest code can be downloaded here.
The documentation for the developments in xmovie can be found here.
