This paper shows that breaking the barrier of 1 triangle/clock rasterization rate for microtriangles in modern GPU architectures in an efficient way is possible. The fixed throughput of the special purpose culling and triangle setup stages of the classic pipeline limits the GPU scalability to rasterize many triangles in parallel when these cover ve...

This work supposes a first attempt to characterize the 3D game workload running on commodity multi-GPU systems. Depending on the rendering workload balance mode used, the intra and inter- frame dependencies due to render-to-texture require a number of synchronizations that can significantly impact the scalability with multiple GPUs. In this paper,...

The rapid pace of change in 3D game technology makes workload characterization necessary for every game generation. Comparing to CPU characterization, far less quantitative information about games is available. This paper focuses on analyzing a set of modern 3D games at the API call level and at the micro architectural level using the Attila simula...

The present work presents a cycle-level execution-driven simulator for modern GPU architectures. We discuss the sim- ulation model used for our GPU simulator, based in the con- cept of boxes and signals, and the relation between the timing simulator and the functional emulator. The simulation model we use helps to increase the accuracy and reduce t...

We present the TILA-rin GPU microarchitecture for embedded systems. We evaluate the architecture using the ATTILA GPU simulation framework. We use a trace from an execution of the Unreal Tournament 2004 PC game to evaluate and compare the performance of the proposed GPU and a baseline GPU architecture for the PC. This work presents the dif- ferent...
