Vulkan compute performance. Blazing fast, mobile-enabled, asynchronous and optimized for advanced GPU data processing usecases. The following document contains recommendations for best practices that achieve performance on NVIDIA hardware. Feb 7, 2023 · This chapter is aimed at both beginners with little to no experience with compute shaders and experienced graphics programmers who want to see how compute acceleration works in Vulkan in practice. By exploiting Vulkan synchronization primitives using the command buffer, we can eliminate the overhead of launching multiple kernel invocations in iterative applications and improve performance of Vulkan Introduction Advantages The Vulkan pipeline An example Data manipulation Shader storage buffer objects (SSBO) Storage images Compute queue families The compute shader stage Loading compute shaders Preparing the shader storage buffers Descriptors Compute pipelines Compute space Compute shaders Running compute commands Dispatch Submitting work Synchronizing graphics and compute Drawing the Jan 4, 2023 · Additionally, I am using timestamp queries in Vulkan code and profiling the Cuda kernel with ncu (can’t make Nsight Graphics work with Vulkan). Also, I ran the code on the Orin board - ~160ms vs 220ms. This sample will look in detail at the implementation and performance implications of the pipeline creation, caching and management. I’m doing a deferred render path, gbuffer renderpass, lighting via a compute shader, then a second renderpass for overlays. General purpose GPU compute framework built on Vulkan to support 1000s of cross vendor graphics cards (AMD, Qualcomm, NVIDIA & friends). Apr 4, 2025 · A Must-Read for GPU Compute Enthusiasts If you’re a programmer seeking to unlock the full potential of GPU compute power, Vulkan Compute: High-Performance Compute Programming with Vulkan and Compute Shaders is an essential addition to your library. This sample aims to demonstrate some techniques we can use to get optimal behavior on tile based renderers in particular. SPIR-V is a binary intermediate representation for graphical shaders and compute kernels. The new Vulkan Compute tutorial steps through how to build a GPU-accelerated particle system simulation, providing insights into: Compute shaders are increasingly being employed to do "everything" except for main pass rasterization in modern game engines. This book dives deep into the world of Vulkan, a cutting-edge graphics and compute API, and explores how to harness its capabilities for high May 8, 2016 · I’ve been having a ball playing around with vulkan. Vkpeak provides Vulkan compute performance measurements for FP16 / FP32 / FP64 / INT8 / BF16 / INT16 / INT32 scalar and vec4 performance. Jun 6, 2019 · Optimal use of Vulkan is not a trivial concept, especially in the context of a large engine, and information about how to maximize performance is still somewhat sparse. 5 ms) on Nvidia Vulkan than on CUDA or on Vulkan with other manufacturers’ GPU. In Vulkan API all shaders (kernels) are presented in SPIR-V format. Vulkan gives applications the ability to save internal representation of a pipeline (graphics or compute) to enable recreating the same pipeline later. Apr 24, 2021 · Vkpeak is a Vulkan compute benchmark inspired by OpenCL's clpeak. Nov 12, 2021 · According to my tests, the usage of local on-chip shared memory doesn’t seem to bring any performance benefit in Vulkan compute shaders on Nvidia GPUs. On Quadro P1000 I have ~280ms for Cuda vs ~970ms for Vulkan - these are the numbers spent in kernel/shader. Vulkan brings the power of modern GPUs to compute, enabling unmatched performance for intensive parallel processing and high-performance computation tasks. I don’t know May 13, 2019 · We show that Vulkan performance is comparable (within 10%) with the performance attained by OpenCL and higher than the performance attained by OpenGL compute shader implementations. However, have now hit some issues that bewilder and confuse (me at least). I have written a test shader that demonstrates this behavior and it is ~30x slower (15 ms vs. 0. . In our implementation we use the glslangValidator for the compute shaders compilation. So a compute pipeline in between two renderpasses. This is all within the same queue, submitted as a single command buffer.
