I designed and built Lightning, the Flash Distributed Framebuffer, with John Owens.
Homan Igehy, Kekoa Proudfoot and I wrote a paper on tolerating memory system latency in a texture caching architecture. Homan and I then extended this work to texture caching in parallel graphics architectures with various rasterization schemes.
Homan Igehy and I developed Pomegranate, a novel parallel hardware architecture for polygon rendering. Pomegranate achieves near-linear scalability at up to 64-way parallelism. Our results are described in a SIGGRAPH 2000 paper.
Gordon Stoll and I took another pass on the original Lightning project to develop Lightning-2 in conjunction with Intel. Our system is described in a SIGGRAPH 2001 paper.
I spent some time working with Greg Humphreys and Ian Buck on scalable cluster rendering. The extension of this system to support the Parallel API is described in a SIGGRAPH 2001 paper.
