Overview
Welcome to the High-Performance Deep Learning project created by the Network-Based Computing Laboratory of The Ohio State University. The availability of large data sets (e.g. ImageNet, PASCAL VOC 2012) coupled with massively parallel processors in modern HPC systems (e.g. NVIDIA GPUs) have fueled a renewed interest in Deep Learning (DL) algorithms. In addition to the popularity of massively parallel DL accelerators like GPUs, the availability and memory-abundance of modern CPUs poses a viable alternative for DL training. This resurgence of DL applications has triggered the development of DL frameworks like Caffe, PyTorch, TensorFlow, Apache MXNet, and CNTK. While most DL frameworks provide experimental support for multi-node training, their distributed implementation is often suboptimal. The objective of the HiDL project is to exploit modern HPC technologies and solutions to scale out and accelerate DL frameworks. The HiDL packages are being used by more than 85 organizations worldwide in 21 countries (Current Users) to accelerate Deep Learning and Machine Learning applications. As of Nov '24, more than 4,550 downloads have taken place from this project's site. The HiDL project contains the following packages.

ParaInfer-X v1.0
ParaInfer-X is a collection of parallel inference techniques that can facilitate the deployment of emerging AI models on edge devices and HPC clusters. It leverages highly performant GPU kernels that maximize computational throughput, intelligent scheduling strategies that ensure optimal load balancing across resources, and sophisticated distributed communication libraries that facilitate large-scale inference by enabling seamless data exchange and coordination among distributed systems.
As a high concurrency application, the large language model serving handles multiple user requests while also targeting a low-latency and high-throughput fashion. ParaInfer-X v1.0 proposes a temporal fusion framework, named Flover, to smartly batch multiple requests during LLM generation, which is also known as temporal fusion/in-flight batching.
