Working with accelerators

Use accelerators, such as NVIDIA GPUs and Intel Gaudi AI accelerators, to optimize the performance of your end-to-end data science workflows.

Overview of accelerators

If you work with large data sets, you can use accelerators to optimize the performance of your data science models in Open Data Hub. With accelerators, you can scale your work, reduce latency, and increase productivity. You can use accelerators in Open Data Hub to assist your data scientists in the following tasks:

  • Natural language processing (NLP)

  • Inference

  • Training deep neural networks

  • Data cleansing and data processing

Open Data Hub supports the following accelerators:

  • NVIDIA graphics processing units (GPUs)

    • To use compute-heavy workloads in your models, you can enable NVIDIA graphics processing units (GPUs) in Open Data Hub.

    • To enable GPUs on OpenShift, you must install the NVIDIA GPU Operator.

  • Intel Gaudi AI accelerators

    • Intel provides hardware accelerators intended for deep learning workloads.

    • Before you can enable Intel Gaudi AI accelerators in Open Data Hub, you must install the necessary dependencies. Also, the version of the Intel Gaudi AI Operator that you install must match the version of the corresponding workbench image in your deployment.

    • A workbench image for Intel Gaudi accelerators is not included in Open Data Hub by default. Instead, you must create and configure a custom notebook to enable Intel Gaudi AI support.

    • You can enable Intel Gaudi AI accelerators on-premises or with AWS DL1 compute nodes on an AWS instance.

Before you can use an accelerator in Open Data Hub, your OpenShift instance must contain an associated accelerator profile. For accelerators that are new to your deployment, you must configure an accelerator profile for the accelerator in context. You can create an accelerator profile from the Settings → Accelerator profiles page on the Open Data Hub dashboard. If your deployment contains existing accelerators that had associated accelerator profiles already configured, an accelerator profile is automatically created after you upgrade to the latest version of Open Data Hub.

Enabling NVIDIA GPUs

Before you can use NVIDIA GPUs in Open Data Hub, you must install the NVIDIA GPU Operator.

Prerequisites

  • You have logged in to your OpenShift Container Platform cluster.

  • You have the cluster-admin role in your OpenShift Container Platform cluster.

Procedure

  1. To enable GPU support on an OpenShift cluster, follow the instructions here: NVIDIA GPU Operator on Red Hat OpenShift Container Platform in the NVIDIA documentation.

  2. Delete the migration-gpu-status ConfigMap.

    1. In the OpenShift Container Platform web console, switch to the Administrator perspective.

    2. Set the Project to All Projects or redhat-ods-applications to ensure you can see the appropriate ConfigMap.

    3. Search for the migration-gpu-status ConfigMap.

    4. Click the action menu (⋮) and select Delete ConfigMap from the list.

      The Delete ConfigMap dialog appears.

    5. Inspect the dialog and confirm that you are deleting the correct ConfigMap.

    6. Click Delete.

  3. Restart the dashboard replicaset.

    1. In the OpenShift Container Platform web console, switch to the Administrator perspective.

    2. Click Workloads → Deployments.

    3. Set the Project to All Projects or redhat-ods-applications to ensure you can see the appropriate deployment.

    4. Search for the rhods-dashboard deployment.

    5. Click the action menu (⋮) and select Restart Rollout from the list.

    6. Wait until the Status column indicates that all pods in the rollout have fully restarted.

Verification

  • The NVIDIA GPU Operator appears on the Operators → Installed Operators page in the OpenShift Container Platform web console.

  • The reset migration-gpu-status instance is present on the Instances tab on the AcceleratorProfile custom resource definition (CRD) details page.

After installing the NVIDIA GPU Operator, create an accelerator profile as described in Working with accelerators.

Intel Gaudi AI Accelerator integration

To accelerate your high-performance deep learning (DL) models, you can integrate Intel Gaudi AI accelerators in Open Data Hub. This allows your data scientists to use Gaudi libraries and software associated with Intel Gaudi AI accelerators from their workbench. Before you can enable Intel Gaudi AI accelerators in Open Data Hub, you must install the necessary dependencies. Also, the version of the Intel Gaudi AI Operator that you install must match the version of the corresponding workbench image in your deployment. However, a workbench image for Intel Gaudi accelerators is not included in Open Data Hub by default. Instead, you must create and configure a custom notebook to enable Intel Gaudi AI support.

You can use Intel Gaudi AI accelerators in an Amazon EC2 DL1 instance on OpenShift. Therefore, your OpenShift platform must support EC2 DL1 instances. Before you can use your Intel Gaudi AI accelerators, you must enable them in your OpenShift environment and configure an accelerator profile for each device. When enabled and fully configured with a custom notebook, Intel Gaudi AI accelerators are available to your data scientists when they create a workbench instance or serve a model.

To identify the Intel Gaudi AI accelerators present in your deployment, use the lspci utility. For more information, see lspci(8) - Linux man page.

Important

If the lspci utility indicates that Intel Gaudi AI accelerators are present in your deployment, it does not necessarily mean that the devices are ready to use.

Working with accelerator profiles

To configure accelerators for your data scientists to use in Open Data Hub, you must create an associated accelerator profile. An accelerator profile is a custom resource definition (CRD) on OpenShift that has an AcceleratorProfile resource, and defines the specification of the accelerator. You can create and manage accelerator profiles by selecting Settings → Accelerator profiles on the Open Data Hub dashboard.

For accelerators that are new to your deployment, you must manually configure an accelerator profile for each accelerator. If your deployment contains an accelerator before you upgrade, the associated accelerator profile remains after the upgrade. You can manage the accelerators that appear to your data scientists by assigning specific accelerator profiles to your custom notebook images. This example shows the code for a Habana Gaudi 1 accelerator profile:

---
apiVersion: dashboard.opendatahub.io/v1alpha
kind: AcceleratorProfile
metadata:
  name: hpu-profile-first-gen-gaudi
spec:
  displayName: Habana HPU - 1st Gen Gaudi
  description: First Generation Habana Gaudi device
  enabled: true
  identifier: habana.ai/gaudi
  tolerations:
    - effect: NoSchedule
      key: habana.ai/gaudi
      operator: Exists
---

The accelerator profile code appears on the Instances tab on the details page for the AcceleratorProfile custom resource definition (CRD). For more information about accelerator profile attributes, see the following table:
