Description
Today we can have huge datasets resulting from computer simulations (CFD, physics,
chemistry etc) and sensor measurements (medical, seismic and satellite). There is
exponential growth in computational requirements in scientific research. Modern
parallel computers and Grid are providing the required computational power for the
simulation runs. The rich visualization is essential in interpreting the large,
dynamic data generated from these simulation runs. The visualization process maps
these datasets onto graphical representations and then generates the pixel
representation. The large number of pixels shows the picture in greater details and
interaction with it enables the greater insight on the part of user in understanding
the data more quickly, picking out small anomalies that could turn out to be critical
and make better decisions. However, the memory constraints, lack of the rendering
power and the display resolution offered by even the most powerful graphics
workstation makes the visualization of this magnitude difficult or impossible. The
initiative to develop high end visual environment at Computer Division, BARC explores
how to build and use a scalable display system for visual intensive applications by
tiling multiple LCD displays driven by the Linux based PC graphics-rendering cluster.
We are using the commodity off-the-shelf components such as PCs, PC graphics
accelerators, network components and LCD displays. This paper focuses on building an
environment which render and drive over 20 millions of pixels, using the open source
software framework. We describe the software packages developed for such a system and
its use to visualize data generated by computational simulations and applications
requiring higher intrinsic display resolution and more display space.
