  Computer Technology has Revolutionized Science. This has motivated scientists
to develop mathematical model to simulate salient features of Physical
universe. These models can approximate reality at many levels of scale such as
atomic nucleus, Earth's biosphere & weather/climate assessment. If the computer
power is greater, the greater will be the accuracy in approximation i.e. close
will be the approximation to the reality. The speed of the computer required
for solution of such problems require computers with processing power of
teraflops to Pets flops speed.. The way to speed up the computation is to
"parallelize" it. One of the approach is to use multimillion dollar
Supercomputer or use Computational Grid (which is also called poor man's
supercomputer) having geographically distributed resources e.g. SETI@home (Used
to detect radio waves emitted by intelligent civilizations outside earth) has
4.6 million participants computers. There are many alternatives tools available
to achieve this goal like Globus Toolkit, Entropia, Legion, BOINC etc but they
are mainly based on Linux platform. As majority of the computers available are
windows based, so it will be easy to develop a larger network of computers
which will use the free cycles of the computer to solve the complex problem at
window platform. Nimble@ITCEcnoGrid has been developed. It includes the feature
of Inter Thread Communication which is missing in any of the toolkits
available. Nimble@ITCEcnoGrid Framework (A Fast Grid with Inter-thread
communication with Economic Based Policy) was tested for computation of 'PI' up
to 120 decimal points. Encouraged by the speed the same system has been
utilized to computes the Momentum, Thermodynamics and Continuity equations for
the Weather Forecasting using the Windows based Desktop computers.
