 +=====Abstract=====
 +The modern real-time graphics pipeline is a versatile parallel
 +architecture that accommodates a wide range of graphics techniques.
 +The architecture is implemented by heavily optimized GPUs that employ
 +a mixture of application-programmable and fixed-function processing
 +resources, yet its design lends itself to a simple programming model
 +easily understood by non-expert programmers.
 +
 +A major goal of future graphics systems is rendering geometrically
 +complex, film-quality scenes at interactive rates. ​ Unfortunately,​
 +current GPU implementations not only require additional compute
 +capability to handle high-resolution surfaces represented by
 +pixel-sized "​micropolygons",​ fundamental system operations such as
 +geometry processing, surface visibility, and shading execute
 +inefficiently under this workload.
 +
 +In this talk I will describe a proposed evolution of the graphics
 +pipeline that increases system efficiency under micropolygon
 +workloads. The redesign includes simultaneous algorithmic,​ GPU
 +hardware, and pipeline abstraction changes that integrate high-quality
 +adaptive tessellation and motion blur, increase rasterization
 +parallelism,​ and reduce shading costs by more than a factor of eight.
 +When making these changes, irregular communication and control-flow
 +are isolated to non-programmable parts of the system, preserving the
 +graphics pipeline'​s simple, implicitly parallel programming model and
 +the throughput-optimized design of the GPU's programmable cores. ​ This
 +"​graphics-style"​ approach to system design is interesting to consider
 +in other compute-intensive domains and in the development of more
 +general parallel computing systems.\\
