high performance computing on graphics processing units: hgpu.org

While general purpose computing on GPUs continues to enjoy higher computing performance with every new generation. The high power consumption of GPUs is an increasingly important concern. To create power-efficient GPUs, it is important to thoroughly study its power consumption. The power consumption of GPUs varies significantly with workloads. Therefore, in this work we study GPU power consumption at a detailed level and its correlation with well-known workload characteristics such as IPC. The low IPC kernels are further explored for the possible bottlenecks.
