VK_KHR_external_memory(3) Manual Page - Khronos Group
WEBAug 30, 2024 · This extension enables an application to export non-Vulkan handles from Vulkan memory objects such that the underlying resources can be referenced outside the scope of the Vulkan logical device that created them.
External Memory and Synchronization :: Vulkan Documentation …
WEBSometimes not everything an application does related to the GPU is done in Vulkan. There are various situations where memory is written or read outside the scope of Vulkan. To support these use cases a set of external memory …
Using Semaphore and Memory Sharing Extensions for Vulkan …
WEBFeb 24, 2022 · New generation GPU APIs such as Vulkan use explicit references to external memory together with semaphores to coordinate access to shared resources. Until now, there have been no OpenCL extensions to enable external memory and semaphore sharing with this new class of API.
External GPU with Vulkan - Stack Overflow
WEBJun 14, 2020 · According to this Vulkan tutorial, I can use vkEnumeratePhysicalDevices to get a list of available GPUs. However, I don't see my external NVIDIA GPU in there, only my Intel iGPU. This eGPU is connected via Thunderbolt and is running CUDA code just fine. Is there anything I might have missed?
How'd multi-GPU programming work with Vulkan? - Stack Overflow
WEBAug 5, 2015 · Look at the vulkan specification for documentation. Vulkan handle all the dispatch to the others GPUs (when they are connected by sli/crossfire). All you need to do is to tell vulkan how the dispatch is done (for example dispatch one frame on a GPU and the next on another one).
Yet another blog explaining Vulkan synchronization – Maister's Graphics …
WEBAug 14, 2019 · Semaphores and fences are quite similar things in Vulkan, but serve a different purpose. Semaphores facilitate GPU <-> GPU synchronization across Vulkan queues, and fences facilitate GPU -> CPU synchronization. These objects are signaled as part of a vkQueueSubmit.
Memory Allocation :: Vulkan Documentation Project
WEBLazily Allocated Memory. On tile-based architectures (virtually all mobile GPUs) the LAZILY_ALLOCATED_BIT memory type is not backed by actual memory. It can be used for attachments that can be held in tile memory, such as the G-buffer between subpasses, depth buffer, or multi-sampled images.
Vulkan Memory Allocator - GitHub
WEBCustomization and integration with custom engines: Predefine appropriate macros to provide your own implementation of all external facilities used by the library like assert, mutex, atomic. Support for memory mapping, reference-counted internally.
