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...
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。 此外, primary context不是必须的,同时和常规context比较起来比较奇怪(例如只能用引用计数方式自动被创建和使用、销毁,而不能...
CUDA Code Samples There are many CUDA code samples included as part of the CUDA Toolkit to help you get started on the path of writing software with CUDA C/C++ The code samples covers a wide range of applications and techniques, including:...

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...
Some samples require that the Microsoft DirectX SDK (June 2010 or newer) be installed and that the VC++ directory paths are properly set up (Tools > Options...). Check DirectX Dependencies section for details. Linux The Linux samples are built using makefiles. To use the makefiles, change...

Several CUDA Samples for Windows demonstrates CUDA-DirectX Interoperability, for building such samples one needs to install Microsoft Visual Studio 2012 or higher which provides Microsoft Windows SDK for ...
