The introduction of General-Purpose computation on GPUs (GPGPUs) has changed the landscape for the future of parallel computing. At the core of this phenomenon are massively multithreaded, data-parallel architectures possessing impressive acceleration ratings, offering low-cost supercomputing together with attractive power budgets. Even given the numerous benefits provided by GPGPUs, there remain a number of barriers […]

Optimizing program execution targeted for Graphics Processing Units (GPUs) can be very challenging. Our ability to efficiently map serial code to a GPU or stream processing platform is a time consuming task and is greatly hampered by a lack of detail about the underlying hardware. Programmers are left to attempt trial and error to produce […]

Loop vectorization, a key feature exploited to obtain high performance on Single Instruction Multiple Data (SIMD) vector architectures, is significantly hindered by irregular memory access patterns in the data stream. This paper describes data transformations that allow us to vectorize loops targeting massively multithreaded data parallel architectures. We present a mathematical model that captures loop-based […]

Efficient visibility queries are key in many interactive rendering techniques, such as occlusion culling, level of detail determination, and perceptual rendering. The occlusion query mechanism natively supported by GPUs is carried out for batches of rendered geometry. In this paper, we present two novel ways of determining visibility by intelligently querying summed area tables and […]
