Abstract

Transistors have been increasing the graphics processing unit’s (GPU) performance since GPUs were first used to conduct scientific research. Currently, Moore’s law is becoming less relevant, and transistors are no longer able to bring a notable performance boost to the GPU. This study outlines different ways that the GPU’s performance can be improved without depending on transistors. In particular, this study focuses on problems associated with the GPU and proposes solutions that help correct those problems. When the GPU is executing dynamic parallelism and fine grain synchronization applications, the GPU performance can decline. To help improve the GPU execute those applications, this study introduces a dynamic parallelism management design and a fine grain synchronization management design. The dynamic parallelism management design and the fine grain synchronization management design are able to bring a 39% and 26% speedup performance improvement for the GPU, respectively. This study also explores a non-uniform memory access (NUMA) based GPU, which is a post Moore’s law era GPU. However, the NUMA based GPU has a problem serving memory requests, which causes it not to reach its full performance potential. To help the NUMA based GPU better serve memory requests, this study introduces several units for the NUMA based GPU. By implementing the units to the NUMA based GPU, the execution time improved by 32%.
