In this paper is presented PyTorch-Direct, a GPU-centric data access paradigm with a novel circular shift indexing optimization for GNN training to reduce training time, CPU utilization, and power consumption. #PyTorch #DeepLearning

arxiv.org/pdf/2101.07956… ImageImageImageImage
PyTorch-Direct presents a new class of tensor called “unified tensor.” While a unified tensor resides in host memory, its elements can be accessed directly by the GPUs, as if they reside in GPU memory.
To support seamless transition of applications from the original PyTorch to PyTorch-Direct, it's presented a programming interface for using unified tensors, giving consistency with the existing PyTorch GPU tensor declaration mechanism.

Researchers have proposed a new class of accelerators named Self Adaptive Reconfigurable Arrays, which comprise of both a reconfigurable array and a hardware unit capable of determining an optimized configuration for the array at runtime.

arxiv.org/pdf/2101.04799…
Also, it's proposed a neural network called ADAPTNET which recommends an array configuration and dataflow for the current layer parameters.

An integrated custom hardware ADAPTNETX runs ADAPTNET at runtime and reconfigures the array, making the entire accelerator self sufficient.
The SARA accelerator implementation (SAGAR) is capable of providing the same mapping flexibility as a collection of 1024 4×4 arrays working as a distributed system while achieving 3.5x more power efficiency and 3.2x higher compute density than the baseline.
