Gpu thrust
WebSep 6, 2014 · Thrust is a header/template library, and so it tends to include a lot of boilerplate code, some of which will be optimized out by the compiler. When you disable these optimizations, it probably has a bigger effect than on a hand-written kernel that is already pretty simple. Webxyzw_frequency_thrust_device 函数使用了CUDA加速的Thrust库,而另一个函数则直接使用了CUDA实现的代码。最后,程序将计算结果从GPU拷贝回主机内存,并输出结果。 3.知识点总结. 3.1 什么是thrust库: Thrust是NVIDIA公司开发的一个C++通用算法库,用于高性能计算和并行计算。
