GPU 优化虚拟机大小GPU optimized virtual machine sizes

GPU 优化 VM 大小是具有单个或多个 NVIDIA GPU 的专用虚拟机。GPU optimized VM sizes are specialized virtual machines available with single or multiple NVIDIA GPUs. 这些大小是针对计算密集型、图形密集型和可视化工作负荷设计的。These sizes are designed for compute-intensive, graphics-intensive, and visualization workloads. 本文介绍有关 GPU、vCPU、数据磁盘和 NIC 的数量和类型的信息。This article provides information about the number and type of GPUs, vCPUs, data disks, and NICs. 此分组中的每个大小还包括存储吞吐量及网络带宽。Storage throughput and network bandwidth are also included for each size in this grouping.

  • NC 系列、NCv2 系列、NCv3 系列尺寸针对计算密集型和网络密集型应用和算法进行了优化。NC-series, NCv2-series, NCv3-series sizes are optimized for compute-intensive and network-intensive applications and algorithms. 例如 CUDA 和基于 OpenCL 的应用程序和仿真、AI 和深度学习。Some examples are CUDA and OpenCL-based applications and simulations, AI, and Deep Learning. NCv3 系列专用于采用 NVIDIA Tesla V100 GPU 的高性能计算工作负载。The NCv3-series is focused on high-performance computing workloads featuring NVIDIA’s Tesla V100 GPU. NC 系列使用英特尔至强 E5-2690 v3 2.60GHz v3 (哈斯韦尔) 处理器,NCv2 系列和 NCv3 系列 VM 使用英特尔至强 E5-2690 v4 (Broadwell) 处理器。The NC-series uses the Intel Xeon E5-2690 v3 2.60GHz v3 (Haswell) processor, and the NCv2-series and NCv3-series VMs use the Intel Xeon E5-2690 v4 (Broadwell) processor.

  • ND系列NDv2系列尺寸侧重于深度学习的训练和推理方案。ND-series, and NDv2-series sizes are focused on training and inference scenarios for deep learning. 他们使用NVIDIA特斯拉P40 GPU和英特尔至强E5-2690 v4(布罗德韦尔)处理器。They use the NVIDIA Tesla P40 GPU and the Intel Xeon E5-2690 v4 (Broadwell) processor. NDv2 系列使用英特尔 Xeon 白金 8168(天湖)处理器。The NDv2-series uses the Intel Xeon Platinum 8168 (Skylake) processor.

  • NV 系列NVv3 系列尺寸经过优化设计,适用于使用 OpenGL 和 DirectX 等框架的远程可视化、流式处理、游戏、编码和 VDI 方案。NV-series and NVv3-series sizes are optimized and designed for remote visualization, streaming, gaming, encoding, and VDI scenarios using frameworks such as OpenGL and DirectX. 这些 VM 由 NVIDIA Tesla M60 GPU 提供支持。These VMs are backed by the NVIDIA Tesla M60 GPU.

  • NVv4 系列针对 VDI 和远程可视化优化和设计的 VM 大小。NVv4-series VM sizes optimized and designed for VDI and remote visualization. NVv4 具有分区 GPU,可为需要较小 GPU 资源的工作负载提供合适的大小。With partitioned GPUs, NVv4 offers the right size for workloads requiring smaller GPU resources. 这些 VM 由 AMD Radeon 本能 MI25 GPU 支持。These VMs are backed by the AMD Radeon Instinct MI25 GPU. NVv4 VM 目前仅支持 Windows 来宾操作系统。NVv4 VMs currently support only Windows guest operating system.

支持的操作系统和驱动程序Supported operating systems and drivers

要利用 Azure N 系列 VM 的 GPU 功能,必须安装 NVIDIA GPU 驱动程序。To take advantage of the GPU capabilities of Azure N-series VMs, NVIDIA GPU drivers must be installed.

NVIDIA GPU 驱动程序扩展可在 N 系列 VM 上安装适当的 NVIDIA CUDA 或 GRID 驱动程序。The NVIDIA GPU Driver Extension installs appropriate NVIDIA CUDA or GRID drivers on an N-series VM. 请使用 Azure 门户或工具(例如 Azure PowerShell 或 Azure 资源管理器模板)安装或管理该扩展。Install or manage the extension using the Azure portal or tools such as Azure PowerShell or Azure Resource Manager templates. 有关受支持的操作系统和部署步骤,请参阅 NVIDIA GPU 驱动程序扩展文档See the NVIDIA GPU Driver Extension documentation for supported operating systems and deployment steps. 有关 VM 扩展的常规信息,请参阅 Azure 虚拟机扩展和功能For general information about VM extensions, see Azure virtual machine extensions and features.

如果选择手动安装 NVIDIA GPU 驱动程序,请参阅适用于 Windows 的N 系列 GPU 驱动程序设置,或针对 Linux 的 N 系列 GPU驱动程序设置,了解支持的操作系统、驱动程序、安装和验证步骤。If you choose to install NVIDIA GPU drivers manually, see N-series GPU driver setup for Windows or N-series GPU driver setup for Linux for supported operating systems, drivers, installation, and verification steps.

部署注意事项Deployment considerations

  • 有关 N 系列 VM 的可用性,请查看可用产品(按区域)For availability of N-series VMs, see Products available by region.

  • N 系列 VM 只能按 Resource Manager 部署模型部署。N-series VMs can only be deployed in the Resource Manager deployment model.

  • N 系列的 VM 在对其磁盘支持的 Azure 存储类型方面有所不同。N-series VMs differ in the type of Azure Storage they support for their disks. NC 和 NV VM 仅支持标准磁盘存储 (HDD) 所支持的 VM 磁盘。NC and NV VMs only support VM disks that are backed by Standard Disk Storage (HDD). NCv2、NCv3、ND、NDv2 和 NVv2 VM 仅支持高级磁盘存储 (SSD) 所支持的 VM 磁盘。NCv2, NCv3, ND, NDv2, and NVv2 VMs only support VM disks that are backed by Premium Disk Storage (SSD).

  • 如果需要部署的 N 系列 VM 较多,请考虑使用即用即付订阅或其他购买选项。If you want to deploy more than a few N-series VMs, consider a pay-as-you-go subscription or other purchase options. 如果使用的是 Azure 免费帐户,则仅可以使用有限数量的 Azure 计算核心。If you're using an Azure free account, you can use only a limited number of Azure compute cores.

  • 可能需要提高 Azure 订阅中的核心配额(按区域)以及单独针对 NC、NCv2、NCv3、ND、NDv2、NV 或 NVv2 核心的配额。You might need to increase the cores quota (per region) in your Azure subscription, and increase the separate quota for NC, NCv2, NCv3, ND, NDv2, NV, or NVv2 cores. 要请求增加配额,请免费打开在线客户支持请求To request a quota increase, open an online customer support request at no charge. 默认限制可能因订阅类别而异。Default limits may vary depending on your subscription category.
