从上面的英文内容我们可以知道默认情况下每个CUDA代码在GPU上运行都会在context下有一个default stream的kernel队列,而这个default stream队列中的kernel执行会阻塞其他stream队列中的kernel操作,从而导致多个stream队列中的kernel操作无法并行。在编译的时候加入参数--default-stream per-thread,就可以使CPU端的每个线程默认调...

A basic kernel benchmark can be created with just a few lines of CUDA C++: void my_benchmark(nvbench::state& state) { state.exec([](nvbench::launch& launch) { my_kernel<<<num_blocks, 256, 0, launch.get_stream()>>>(); }); } NVBENCH_BENCH(my_benchmark); See Benchmarks for...
它的所有入口都以cuda为前缀。 如异构编程中所述,CUDA 编程模型假设系统由主机和设备组成,每个设备都有自己独立的内存。设备内存概述了用于管理设备内存的运行时函数。 共享内存说明了使用线程层次结构中引入的共享内存来最大化性能。 Page-Locked Host Memory引入了 page-locked 主机内存,它需要将内核执行与主机设备内...
