Efficient Design Space Exploration of GPGPU Architectures

摘要

The goal of this work is to revisit GPU design and introduce a fast, low-cost and effective approach to optimize resource allocation in future GPUs. We have achieved this goal by using the Plackett-Burman methodology to explore the design space efficiently. We further formulate the design exploration problem as that of a constraint optimization. Our approach produces the optimum configuration in 84% of the cases, and in case that it does not, it produces the second optimal case with a performance penalty of less than 3.5%. Also, our method reduces the number of explorations one needs to perform by as much as 78%.
