Today, we’re pleased to announce the Deep Learning Reference Stack (DLRS) v7.0 release that features Intel® Advanced Vector Extensions 512 (Intel® AVX-512) with Intel® Deep Learning Boost (Intel® DL Boost) and the bfloat16 (BF16) extension. Intel DL Boost accelerates AI training and inference performance. In response to customer feedback, release v7.0 offers an enhanced user experience with support for the 3rd Gen Intel® Xeon® Scalable processor, the 10th Gen Intel® Core™ processor, the Intel® Iris® Plus graphics, and the Intel® Gaussian & Neural Accelerator (Intel® GNA).

DLRS v7.0 further improves the ability to quickly prototype and deploy DL workloads, reducing complexity while allowing customization. This release features:

  • TensorFlow* 1.15.3 and TensorFlow* 2.4.0 (2b8c0b1), end-to-end open source platform for machine learning (ML).
  • PyTorch* 1.7(458ce5d) open source machine learning framework that accelerates the path from research prototyping to production deployment.
  • PyTorch Lightning, lightweight wrapper for PyTorch designed to help researchers set up all the boilerplate state-of-the-art training.
  • Transformers, state-of-the-art Natural Language Processing (NLP) for TensorFlow 2.4 and PyTorch.
  • Flair, library for state-of-the-art Natural Language Processing using PyTorch
  • OpenVINO™ model server version 2020.4, delivering improved neural network performance on Intel processors, helping unlock cost-effective, real-time vision applications [1]
  • TensorFlow Serving 2.3.0, Deep Learning model serving solution for TensorFlow models.
  • Horovod 0.20.0 framework for optimized distributed Deep Learning training for TensorFlow and PyTorch.
  • oneAPI Deep Neural Network Library (OneDNN) 1.5.1 accelerated backends for TensorFlow, PyTorch and OpenVINO
  • Intel DL Boost with Vector Neural Network Instruction (VNNI) and Intel AVX-512_BF16 designed to accelerate deep neural network-based algorithms.
  • Deep Learning Compilers (TVM* 0.6), an end-to-end compiler stack.
  • Seldon Core (1.2) and KFServing (0.4) integration examples with DLRS for deep learning model serving on a Kubernetes cluster.

Benefits of the Deep Learning Reference Stack

One highlight of DLRS v7 is its ability to use the new Intel AVX-512 extension for bfloat16 (AVX-512_BF16), which allows the user to accelerate deep learning training operations on 3rd Gen Intel® Xeon® Scalable processors. We have enabled this functionality for both Tensorflow and PyTorch frameworks (Figure 1).

The 3rd Gen Intel® Xeon® Scalable processors also support accelerated INT8 convolutions with AVX 512 VNNI [2] instructions for higher levels of inference performance. In DLRS v7.0, we added a dedicated serving container to our suite of optimized stacks that includes hardware accelerated OpenVINO model server 2020.4 (Figure 2). This stack can utilize Intel DL Boost features on 10th Gen Intel® Core™ processors (IceLake) and is also optimized for Intel® Iris® Plus graphics. Additionally, the stack is also Intel GNA ready on Intel client processors. The Intel GNA provides power-efficient acceleration for AI applications such as neural noise cancellation while freeing up CPU resources for overall system responsiveness.

Enabling Deep Learning Use Cases

As a platform for building and deploying portable, scalable, machine learning (ML) workflows, Kubeflow Pipelines* support deployment of DLRS images easily. This enables orchestration of machine learning pipelines, simplifying ML Ops, enabling the management of numerous deep learning use cases and applications. DLRS v7.0 also incorporates Transformers , a state-of-the-art general-purpose library that includes a number of pretrained models for Natural Language Understanding (NLU) and Natural Language Generation (NLG). The library helps to seamlessly move from pre-trained or fine-tuned models to productization. DLRS v7.0 incorporates Natural Language Processing (NLP) libraries to demonstrate that pretrained language models can be used to achieve state-of-the-art results [3] with ease. NLP Libraries included can be used for natural language processing, machine translation, and building embedded layers for transfer learning. For the PyTorch-based DLRS, this release also extends support for Flair [4], which includes the ability of Transformers, to apply natural language processing (NLP) models to text, such as named entity recognition (NER), part-of-speech tagging (PoS), sense disambiguation, and classification. In addition to the Docker* deployment model, DLRS is integrated with Function-as-a-Service (FaaS) technologies, which are scalable event-driven compute platforms. One can use frameworks such as Fn [5] and OpenFaaS [6] to dynamically manage and deploy event-driven, independent inference functions. We have created an OpenFaaS template (available already in the OpenFaaS template store) that integrates DLRS capabilities with this popular FaaS project. For DLRS v7, we have updated it to use the latest version of DLRS with Tensorflow 1.15 and Ubuntu 20.04, but it can be extended to any of the other DLRS flavours. One can use end-to-end use cases for the Deep Learning Reference Stack to help developers quickly prototype and bring up the stack in their environments. Some end to end use-cases of such deployments are:

  • Galaxies Identification: Demonstrates the use of the Deep Learning Reference Stack to detect and classify galaxies by their morphology using image processing and computer vision algorithms on Intel® Xeon® processors.
  • Using AI to Help Save Lives: A Data Driven Approach for Intracranial Hemorrhage Detection: AI training pipeline to help detect intracranial hemorrhage (ICH)
  • Github Issue Classification Use Case: Used to auto-classify and tag issues using the Deep Learning Reference Stack for deep learning workloads
  • Pix2pix: Can be used to perform image to image translation using end-to-end system stack
     

Supported Tools and Frameworks

This release also supports the latest versions of popular developer tools and frameworks:

  • Operating SystemUbuntu* 20.04, Ubuntu* 18.04, and CentOS* 8.0 Linux*

    distributions.
