Petascale Ideas

• What could visualization do with Petascale
  Computing?

20
Why Is Visualization Unique?

• Fixed resolution and speed output device.
• No matter how much simulation data is produced
  the visual presentation is limited to a finite
  resolution and speed.
• Can play with that a little IMAX, 60 fps but
  practically fixed.

21
Where Is Industry Headed?

• Larger and Larger Render Farms WETA in New
  Zealand.
• More and more powerful GPUs with SLI the nVidia
  cards in this machine.

22
What Appears Appealing?

• Incredibly Photoreal renderering this is
  coming. Movies will drive it. Games will adopt
  it as it arrives.

23
What Appears Appealing?

• Real-time feature film video editing.
• A Scanner Darkly done over-night.

24
What Appears Appealing?

• Full facial database search of entire football
  stadium during the game.
• Automated computer search of surveilance footage.
• Makes it worthwhile to save EVERYTHING and
  actually be able to search and use the footage.

25
What Appears Appealing?

• Intel is planning large-scale multi-core systems.
• No separate GPU. Simply allocate multiple cores
  to the rendering process.
• Full computation on the core, full access to
  system memory, can do multi-cpu supersampling and
  rendering.

26
What Appears Appealing?

• Lots of predictive pre-rendering.
• For example Architectural walk-through of a very
  large CAD model.
• Load the large model onto the machine. Start
  viewing at one location. While in that location
  the petascale system is predictively rendering
  views that are easily accessible from the current
  location.
• Would work well for say a Boeing 777 CAD model.

27
What Appears Appealing?

• Render out all parameterized variations on a
  rendering algorithm for a scene or visualization.
• Then the user simply selects amongst the multiple
  outputs.

28
What Appears Appealing?

• Personalized Digital Cinema
• Assume a highly synthetic movie.
• User can adjust location, position, and
  orientation of various objects within the film
  and the system can begin rendering and playback
  almost immediately.
• Key Component Here is Petascale.

29
What Appears Appealing?

• Interactive multiple parameter computational
  steering.
• Dont run larger simulations run more of them
  with varying parameters.
• Visualization lets you adjust the parameters and
  you can launch many simulations to sweep out the
  results.
• Rule for Petascale Never Run Just One Job.

30
What Appears Most Likely?

• Very high resolution synthetic movie scenes are
  almost a certainty.
• Massive image database searches.
• Anything that can be cast into a search paradigm
  will probably be developed quickly.
