Today Maxime Vanliefde presented xPUBench: Scalable and Energy-Efficient GPU and DPU-Accelerated Network Functions at #PAM2026
This is a collaboration with Nikita tyunyayev Clément Delzotti, Romain Van Hauwaert and Elena Agostini (NVIDIA). We benchmark network packet processing on GPU, DPU, and CPU and a combination of them, hence the name, xPU (Bench).
We also take a novel angle on energy efficiency, with techniques to use less power for GPU (reducing uncore frequency), and show that DPU are highly efficient… but limited in term of processing power. When they match, they’re best. For complex workloads, GPU are the way to go and are even more energy efficient than CPUs.
Many more findings in the paper!
