NVIDIA HPC SDK虽然附带了CUDA、cuBLAS等库,但安装路径与CUDA Toolkit有差异。cuda-samples有些示例用到了cuBLAS等数学库,按照文档直接make会找不到库文件。 翻找示例的Makefile想找全局的设置,发现有行ALL_CCFLAGS += $(EXTRA_NVCCFLAGS),其中EXTRA_NVCCFLAGS在Makefile中未出现过,推测是全局的额外参数。再往下看...
%CUDA_BIN_PATH% %CUDA_SDK_LIB_PATH% %CUDA_SDK_BIN_PATH% 1. 2. 3. 4. 错误路径“C:\Program Files\NVIDIA Corporation”下,发现找不到CUDA Samples文件夹。 实际上是因为ProgramData是一个隐藏文件夹,需要设置【我的电脑】-【查看】-【显示隐藏文件】才能看到,因此这个才是正确路径“C:\ProgramData\NVI...

注意,这点并不能直接提高性能,但是交互操作,能让你切换到使用runtime api,从而节省了你的时间。你节省的时间可以用来优化成本,或者花费到优化代码的其他方面,来提升性能。例如这里举例的Video Code SDK Samples代码,就可以直接方面的改成简单版本的runtime api版的,能节省很多的开发时间。

* This sample revisitsmatrix multiplicationwith CUDA task. The code of matrix * multiplication is exactly the same as in matrixMulDrv sample of this SDK. * This sample, however, demonstrates how to link CUDA driver at runtime and * how to perform JIT (just-in-time) compilation of CUDA ke...
‣ Removed DirectX SDK (June 2010 or newer) installation requirement, all the DirectX-CUDA samples now use DirectX from Windows SDK shipped with Microsoft Visual Studio 2012 or higher www.nvidia.com CUDA Samples TRM-06704-001_v11.0 | 2 Release Notes 1.4. CUDA 10.1 Update 1 ‣ ...
而GPU存在很多CUDA核心, 充分利用CUDA核心可以发挥GPU的并行计算能力。‘ SM的核心组件包括CUDA核心,共享内存,寄存器等,SM可以并发地执行数百个 线程,并发能力就取决与SM所拥有的资源数。 3.SIMI–(Single-Intruction, Multiple-Thread)单指令多线程 基本的执行单元是线程束(wraps),线程束包含32个线程,这些线程同时...
On Windows, to build and run MPI-CUDA applications one can install MS-MPI SDK. Only 64-Bit Some samples can only be run on a 64-bit operating system. DirectX DirectX is a collection of APIs designed to allow development of multimedia applications on Microsoft platforms. For Microsoft ...
