WebApr 29, 2016 · I want to override the low-level CUDA device memory allocator (implemented as thrust::system::cuda::detail::malloc ()) so that it uses a custom allocator instead of call directly to cudaMalloc () when invoked on a host (CPU) thread. Is this possible? If so, is it possible to use the Thrust "execution policy" mechanism to do it? 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。 … phillip copley

This library's central feature is a high-level vector container that is similar C++'s own vector container. While this may sound trivial, this will allow us to program in CUDA C with less reliance on pointers, mallocs, and frees. phillip copley upper arlington ohio
