GTC 2018Dissecting the Volta GPU Architecture throughMicrobenchmarkingZhe Jia, Marco Maggioni, Benjamin Staiger, Daniele P. ScarpazzaHigh-Performance Computing Group• Micro-architectural details matter – crucial to achieve peak performance• Hard to keep up-to-date– new GPU generations every year– complexity increases at every generation• Everything is better on Volta... but how much?• We describe the inner workings of Volta– instruction encoding– size, properties, performance of each level in the
