[NVIDIA TF] Optimize Bilinear image resize using SSE instructions on x86 CPUs
Hi @nluehr Can you please check @cantonios's comments and keep us posted ? Thank you!
With these changes I see an 18% improvement in single threaded bi-linear resize performance on x86 CPUs (based on resizing full-sized imagenet inputs to 224x224 pixels). Including disk IO and jpeg decode, the improvement dilutes to ~5%. But on multi-GPU systems where image pre-processing can represent a significant bottleneck, this 5% can translate directly to an overall 5% wall-time speedup.
