CUDA (Compute Unified Device Architecture) is a parallel computing platform and API that lets you interact more directly with the GPU for general purpose computing. In practice, this means that a developer can write code in C, C++, or many other supported languages utilizing their GPU to create...
www.nvidia.com Nsight Compute v2021.2.1 | 3 Release Notes 1.4. Updates in 2021.1 General ‣ Added support for the CUDA toolkit 11.3. ‣ Added support for the OptiX 7 API. ‣ GpuArch enumeration values used for filtering in section files were renamed from architecture names to ...
c = torch.matmul(a, b) #cpu模式的矩阵乘法 t1 = time.time() #结束时刻 print(a.device, t1 - t0, c.norm(2)) #首次使用cuda,会需要初始化,耗时会长一些 device = torch.device('cuda') a = a.to(device) b = b.to(device) t0 = time.time() ...
| CUDA(Compute Unified Device Architecture,统一计算架构)是一个基于英伟达 GPU 平台上面定制的特殊计算体系/算 法,一般只能在英伟达的 GPU 系统上使用。CUDA 是一种类 C 语言,本身也兼容 C 语言,所以其虽然是一种独立语言,但 CUDA 本身和 C 差距不算很大,适合普通开发者 使用且能够最大化 GPU 的计算效率,这...
然后,Nsight Compute 会启动应用程序,并允许它继续进行第一个 CUDA 调用。此步骤可能需要大约 10 秒,具体取决于我们的 CPU,因为代码正在设置和初始化 4 GB 内存。我们尚未分析任何内容。由于应用程序中只有一个内核(仅调用一次),因此可以通过选择" Auto Profile",选择" Full "部分集,然后选择"Run to Next Kernel...

The number of registers is limited, and will vary from platform to platform. When the limit is exceeded, register variables will be spilled to memory, causing changes in performance. For each architecture, there is a recommended maximum number of registers to use (see the "CUDA Programming ...
