Intel MKL-DNN Deep Neural Network Library Benchmarks On Xeon & EPYC

Ned, 10/06/2019 - 12:24
This week Intel released MKL-DNN 1.1 as their open-source deep learning library. They also rebranded the software project as the "Deep Neural Network Library" (DNNL) though its focus remains the same. I ran some initial benchmarks on MKL-DNN/DNNL 1.1 on AMD EPYC and Intel Xeon hardware for reference...

Radeon RADV "ACO" Performance On Mesa 19.3 Looking Good

Ned, 10/06/2019 - 01:17
With the ACO shader compiler back-end merged for Mesa 19.3 as of mid-September and more improvements merged since then, it's now very easy to try out this alternative to AMD's longstanding AMDGPU LLVM compiler back-end. ACO, which is developed by Valve and their contractors outside of AMD, is looking quite good not only for quicker shader compilation (more punctual game load times) but also helping the performance of some Vulkan-powered games. Here are our latest ACO benchmarks.

Linux Returns To Parallel CPU Microcode Updates To Reduce Cloud Disruption

Pet, 10/04/2019 - 12:12
