For example if multiple threads within a block are each launching work and synchronization is desired for all this work at once (perhaps because of event-based dependencies), it is up to the program to guarantee that this work is submitted by all threads before calling cudaDeviceSynchronize()....
N.2.3.1. Host Program Errors withmanagedVariables __managed__变量的使用取决于底层统一内存系统是否正常运行。 例如,如果 CUDA 安装失败或 CUDA 上下文创建不成功,则可能会出现不正确的功能。 当特定于 CUDA 的操作失败时,通常会返回一个错误,指出失败的根源。 使用__managed__变量引入了...
