Predicting GPU Kernel's Performance on Upcoming Architectures

Lucas Van Lanker, Hugo Taboada, Elisabeth Brunet, François Trahay

Abstract: With the advent of heterogeneous systems that combine CPUs and GPUs, designing a supercomputer becomes more and more complex. The hardware characteristics of GPUs significantly impact the performance. Choosing the GPU that will maximize performance for a limited budget is tedious because it requires predicting the performance on a non-existing hardware platform.
