Pretty baller if i do say so myself !!!!!!!!!!!

"Deep Learning (DL) algorithms are the central focus of modern machine learning systems. As data volumes keep growing, it has become customary to train large neural networks with hundreds of millions of parameters to maintain enough capacity to memorize these volumes and obtain state-of-the-art accuracy. To get around the costly computations associated with large models and data, the community is increasingly investing in specialized hardware for model training. However, specialized hardware is expensive and hard to generalize to a multitude of tasks. The progress on the algorithmic front has failed to demonstrate a direct advantage over powerful hardware such as NVIDIA-V100 GPUs. This paper provides an exception. We propose SLIDE (Sub-LInear Deep learning Engine) that uniquely blends smart randomized algorithms, with multi-core parallelism and workload optimization. Using just a CPU, SLIDE drastically reduces the computations during both training and inference outperforming an optimized implementation of Tensorflow (TF) on the best available GPU. Our evaluations on industry-scale recommendation datasets, with large fully connected architectures, show that training with SLIDE on a 44 core CPU is more than 3.5 times (1 hour vs. 3.5 hours) faster than the same network trained using TF on Tesla V100 at any given accuracy level. On the same CPU hardware, SLIDE is over 10x faster than TF. We provide codes and scripts for reproducibility"

Infrastructure:
All the experiments are conducted on a
server equipped with two 22-core/44-thread processors (In-
tel Xeon E5-2699A v4 2.40GHz) and one NVIDIA Tesla
V100 Volta 32GB GPU. T

Oh... on old hot Xeons... imagine the Epyc SLIDING on a current platform.

Two of the credited authors work for Intel, might have a tough time extracting teeth on that one. :p

Also, hashing isn't free, and SLIDE seems to completely rely on it, while being vague in their benchmarks.

r/MachineLearning seems even more skeptical than me, though.
