Computer architecture, graphics hardware, computer graphics and embedded systems.
My research work is focused on improving SIMT processor thread divergence using a mixture of custom architectures and programming models that allows for individual threads to spawn new threads during runtime and are then grouped into new warps. Current research work expands thread spawning for improving memory divergence and other warp formation options. Reducing memory overhead during thread spawning through locality of existing memory systems used in SIMT architectures is also being researched.
Researched new graphics architectures for supporting global rendering algorithms. This work was focused on developing acceleration algorithms capable of fixed hardware acceleration for ray-tracing. Additional research developed new global rendering algorithms designed for hardware acceleration with the goal of utilizing current graphics hardware.
