I'll be putting together a few slides that will be shown in the SGI theater in addition to running the demos on a small 12p system on the show floor and a larger 64p system in Mountain View (using vizserver). The primary demo is a walk through of the Boeing 777. The dataset can be explored with both opaque and transparent surfaces. We also plan to have a 160 GB volume dataset displayed from a remote system using vizserver. There will be a ray tracing oriented materials demo, however the focus is definitely on big data rather then other ray tracing effects.

I did some informal scaling tests up to 384 at the beginning of the summer, I will try to dig up those slides. I'll also send you some additional images (probably late Friday).

I just reserved a 128 processor machine for 5 hours on Friday. I'll run some more scaling tests and get you some data for the Boeing demo on that system.
The Manta demos will be available Tuesday, Wednesday, Thursday at the SGI booth. I will be at the booth:

Tuesday: (after 10:15)
Wednesday: (2-6pm)
Thursday: (10:15am-1pm)

At other times, the demos may still be available depending on who is around.

One point that I think needs to be made, is that super computers provide an environment where we can concentrate on visualization--and not have to worry about out-of-core issues, level of detail, or other approximation schemes. There are only two parts to the Boeing demo, a kdtree and a ray tracer--it's really quite simple.

Hi guys-- a week from today I'll be presenting 30min on shared-memory multiprocessor ray tracing. Philipp S will
be talking about cluster implementations.  So please
let me know if you have any slides, images, or data that
would be useful.  Also, is the SGI demo a go?  If so
including a slide on when/where it is would be good.

I am also talking about volume rendering (iso and direct)
so any slides/images etc for that would also be useful
but I am in better shape there (most of the slides from
Steve's and my ancient viz talk are still on target!)

Thanks!

Pete
