GSI: a GPU stall inspector to characterize the sources of memory stalls for tightly coupled GPUs

In recent years the power wall has prevented the continued scaling of single core performance. This has led to the rise of dark silicon and motivated a move toward parallelism and specialization. As a result, energy-efficient high-throughput GPU cores are increasingly favored for accelerating data-parallel applications. However, the best way to efficiently communicate and synchronize across heterogeneous cores remains an important open research question. Many methods have been proposed to improve the efficiency of heterogeneous memory systems, but current methods for evaluating the performance effects of these innovations are limited in their ability to attribute differences in execution time to sources of latency in the memory system. Performance characterization of tightly coupled CPU-GPU systems is complicated by the high levels of parallelism present in GPU codes. Existing simulation tools provide only coarse-grained metrics which can obscure the underlying memory system interactions that cause performance differences. In this thesis we introduce GPU Stall Inspector (GSI), a method for identifying and visualizing the causes of GPU stalls with a focus on a tightly coupled CPU-GPU memory subsystem. We demonstrate the utility of our approach by evaluating the sources of stalls in several recent architectural innovations for tightly coupled, heterogeneous CPU-GPU systems

We thank Catalina Luneburg and Stephen Laubach for efficient editorial handling, together with Ruth Soto and Manish A. Mamtani for helpful reviews and constructive comments. RW was inspired by John Ramsay while participating in a fieldtrip to the Alps led by John in 2002. GIA would like to take this opportunity to acknowledge John Ramsay's support while a post-doc at ETH Zurich in the late 1980's. TL had the privilege of showing John Ramsay outcrops of slump horizons and seismites in the lacustrine sediments of the Dead Sea region during John's visit to Israel in 2008.Peer reviewedPostprin
