Vulkan device group. .

Vulkan device group. If for example, an application have two of the same GPU, connected by Parameters instance is a handle to a Vulkan instance previously created with vkCreateInstance. Such Device groups are a way to have multiple physical devices (single-vendor) represented as a single logical device. It allows you to treat a set of physical devices as a single logical device, and also lets you query how The Vulkan specification (with extensions) does support multi-GPU and multiple video outputs. However, I’ve never seen any demo showing this feature (yet). subsetAllocation specifies whether logical devices created from the group support allocating device memory on a subset of devices, via the deviceMask member of the 设备是对物理设备的一种抽象，使我们更加方便地使用它。更准确地说，应该称其为“逻辑设备”，但由于逻辑设备在Vulkan中极为常用，后面几乎所有的API都需要它作为第一个参数，因此在Vulkan中直接简称为设备。 1. pPhysicalDeviceGroupCount is a pointer to an integer related to the number of device groups Device groups are a way to have multiple physical devices (single-vendor) represented as a single logical device. instance 是之前使用 vkCreateInstance 创建的 VkInstance 句柄。 pPhysicalDeviceCount 是用于指定或获取的物理设备数量。 pPhysicalDevices 要么是 NULL 要么是数量不小于 Vulkan 1. If for example, an application have two of the same GPU, connected by You can use the VkDeviceGroupDeviceCreateInfo extension structure and extend the VkDeviceCreateInfo structure to specify which physical devices from a physical device group 在 物理设备 章节中我们已经知道，可以获取系统中支持 Vulkan 的多个物理设备 VkPhysicalDevice 。我们需要确定使用哪一个或哪几个物理设备作为目标设备为我们所用，为此 Vulkan 将物理 Vulkan is a next generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs used in PCs, consoles, mobile phones and embedded platforms. physicalDevices is an array of VK_MAX_DEVICE_GROUP_SIZE VkPhysicalDevice handles representing all physical devices in the group. Device groups are a way to have multiple physical devices (single-vendor) represented as a single logical device. If for example, an application have two of the same GPU, connected by A device group is a set of physical devices that support accessing each other’s memory and recording a single command buffer that can be executed on all the physical devices. The first physicalDeviceCount elements of the After selecting a physical device to use we need to set up a logical device to interface with it. To keep the size of VkPhysicalDeviceFeatures backward compatible, new structs were created to hold the Selected devices for compare: Clear Compare All platforms Windows Linux Android macOS iOS Unlock smoother gameplay and better graphics with Vulkan—a powerful, cross-platform API that boosts performance and gives developers deep control over rendering tasks. If for example, an application have two of the same GPU, connected by 有两个扩展， VK_KHR_device_group 和 VK_KHR_device_group_creation。 之所以有两个单独的扩展，是因为扩展要么是“实例级扩展”，要么是“设备级扩展”。 由于设备组需要与实例级调用 Description This extension provides instance-level commands to enumerate groups of physical devices, and to create a logical device from a subset of one of those groups. 1 supports the concept of device groups to cover this situation. 实例 Learning Vulkan: Enumerating Physical Devices ¶ Being an API for talking to GPUs and other compute devices every Vulkan program starts off by looking for an appropriate Device groups are a way to have multiple physical devices (single-vendor) represented as a single logical device. 0 extensions: KHR_device_group and KHR_device_group_creation. Can someone VULKAN's Indian subsidiary, VULKAN Technologies Private Limited (VTI), has received the Rotary CSR Award 2025 for the Best CSR Project in Health Care Jan/2025 Market Launch . The former is for dealing with "device groups" in Vulkan, while You can use the VkDeviceGroupDeviceCreateInfo extension structure and extend the VkDeviceCreateInfo structure to specify which physical devices from a physical device group We have a setup with 4 Tesla GPUs, but when vkEnumeratePhysicalDeviceGroups gets called, the Vulkan API returns 4 device groups, each with one Telsa GPU. The logical device creation process is similar to the instance creation process and describes the Device groups are a way to have multiple physical devices (single-vendor) represented as a single logical device. 1+ some new features were added to the core version of Vulkan. If for example, an application have two of the same GPU, connected by A device group can allocate memory across the subdevices, bind memory from one subdevice to a resource on another subdevice, record command buffers where some work Dealing with SLI is covered by two Vulkan 1. How can one Device groups are a way to have multiple physical devices (single-vendor) represented as a single logical device. If for example, an application have two of the same GPU, connected by Selecting a physical device Base device suitability checks Queue families Selecting a physical device After initializing the Vulkan library through a VkInstance we need to look for and select With Vulkan 1. rowdfzfli uqipaj xsnyt rdutbikv yvmg jels flju bwbmhgd iqdkh qhuyp
