CUDA解决了并行处理的问题，借助GPU的能力。
安装了新版的工具包，vs2017。根据例程运行报错了。目前还没解决。
目前不确认我的显卡是否足够sm去运行。买了三本书，一本英文版，看了有点吃力。一本中译英，写了比较啰嗦。一本中文版，又感觉有点难。慢慢啃吧。
更新了显卡驱动。感觉可以运行了。
有关计算能力的说明。很明显我的卡是6.1,基于Pascal架构.
设备的计算能力由版本号表示，有时也称为“ SM版本”。此版本号标识GPU硬件支持的功能，并由应用程序在运行时用于确定当前GPU上可用的硬件功能和/或指令。
计算能力包括主要修订号X和次要修订号Y，并由XY表示。
具有相同主要版本号的设备具有相同的核心体系结构。主要修订号对于基于NVIDIA Ampere GPU架构的设备为8 ，对于基于Volta架构的设备为7 ，对于基于Pascal架构的设备为6 ，对于基于Maxwell架构的设备为5 ，对于基于开普勒的设备为3 架构，2个用于基于Fermi架构的设备，1个用于基于Tesla的设备 建筑。
Pascal的GPC有6个SM，每个SM只含有64个CUDA Core，但是拥有64个FP32单元32个FP64单元，FP64与FP32比例达到了1：2，双精度性能大幅度提高，而Pascal的FP32单元可以同时执行2个FP16半精度运算，因此FP16浮点性能也同样获得极大提升。
