GPUs have been widely used for computer graphics and visualization
applications in geospatial fields for years. But today's GPUs are
powerful for general purpose computing -- General Purpose Computing
on the Graphics Processing Unit (GPGPU). GPGPU leverages the microprocessors
that power many modern graphics cards. GPGPU has great promise for
bringing the distributing processes to the geospatial research and
application, such as point clouds based LiDAR data processing and
large remote sensing image processing, etc.
NVIDIA Keynote: GPUs & Geospatial
Dr. David Luebke
Computer graphics and image processing are among the
most important tools for geospatial applications, so it
is no surprise that graphics algorithms and hardware
have long played a vital role in geospatial computing.
For example, TIN or DEM terrain modeling makes heavy use
of computer graphics algorithms; real-time large terrain
visualization employs view-dependent level of detail
(LOD) techniques; remote sensing and feature extraction
applications often use the image processing and computer
vision prowess of graphics hardware; stereo rendering
provides a useful tool for visualization; and point
cloud rendering is a crucial component for LIDAR data
processing. Of course all these rendering and
visualization tasks ultimately take place on a graphics
processing unit, or GPU.
However, modern GPUs have
outgrown their graphics heritage in many ways to emerge as the
world's most successful parallel computing architecture. The raw
computational horsepower of these chips has expanded their reach
well beyond graphics. Their massively parallel computational
approach isn't just a good idea, it is the only path forward for
scalable computing: if your code isn't intrinsically parallel,
you will not be able to tackle ever-bigger problems in the
future. I will discuss some of the technological and business
imperatives driving modern parallel computing, and close with
some examples of GPU parallel computing in geospatial
processing. Read more...>>
