3 Introduction Cloud GPU enables you to supplement your on-platform compute resources with GPU capabilities. This service enables you to use UKCloud s main infrastructure platforms to meet the specialist requirements of some advanced applications, with the benefits of a cloud environment. It supports the following types of workloads: Compute workloads. GPUs have become prevalent in a world that needs a lot of data processing, fast. The parallel nature of GPU cores lends itself perfectly to supporting initiatives such as deep or machine learning and large-scale mathematical modelling. Visualisation workloads. Describes the traditional use cases for GPU processing these include simulation, powering desktop applications with graphics content (such as computer aided design), video encoding, rendering or streaming. This Getting Started Guide provides an introduction for how to use Cloud GPU for compute workloads and describes the tasks you need to perform to get the service up and running. Intended audience To complete the steps in this guide you must have access to the UKCloud Portal and vcloud Director. Cloud GPU overview We offer two GPU variants for use with our cloud platform: Use case Compute Visualisation Likely card NVIDIA Tesla P100 NVIDIA M60 Series Card with GRID Overview NVIDIA Tesla P100 GPU accelerators are the most advanced ever built.

4 With Cloud GPU, you can: Process large data sets The significantly improved computational power provided by Cloud GPU means that you can gain insight into your data by using the massively parallelised capabilities to process large data sets. This enables: o Parallel processing of data in a fraction of the time of using just CPU o Machine learning, deep learning, artificial intelligence o Mathematical modelling and data sequencing o Healthcare modelling o Predictive threat analysis Bring any application to the cloud Applications that have previously struggled to transition to the cloud because of GPU requirements can now be moved, improving manageability of your data and applications, while increasing collaborative opportunities. Centralise your applications Cloud GPU enables you to centralise your applications to improve access to them. By doing so, users can access the tools they need from anywhere, anytime on commodity devices. Visualise data in real-time Improved visualisation capabilities provided by Cloud GPU enables you to visualise data in real-time to render virtualised environments when you need them. This helps you to: o Design using Computer Aided Design applications in a centralised environment, enabling ease of collaboration o Create and run simulations o Render and analyse high resolution images and video Before you begin When using our Cloud GPU service for compute workloads, you should consider the following: Your Cloud GPU virtual machine (VM) must be in a PRIORITY virtual data centre (VDC). You should create your Cloud GPU VM using the appropriate UKCloud template from the GPGPU public catalogue. Your deployed Cloud GPU VM should be using hardware version 11. The shell VM in the Cloud GPU VM template uses hardware version 11. Snapshot Protection is not available for your VM, so you must implement your own backup solution. Currently, there is no high availability or disaster recovery option; your VM cannot be migrated to a different host in the event of host failure. In the event of a host failure, you must wait for the host to be returned to service. UKCloud Ltd, 2017 Open Page 4 of 14

5 Creating your virtual machine Before you request your Cloud GPU service, you must create a VM for the service using the UKCloud GPU-enabled template. 1. Log in to the UKCloud Portal.
