》计算能力在5.0或者更高的设备上,可以从设备端调用(更多的细节可见CUDA Dynamic Parallelism) 一个__global__函数必须返回void类型,不能是类函数class的成员函数。 任何调用了__global__函数的调用,必须指定它的执行配置,就像这里面描述的那样Execution。 7.1.2. __device__ __device__执行空间说明符,声明了一...
chap 9.5 CUDA Dynamic Parallelism (CDP)
Dynamic Parallelism是 CUDA 编程模型的扩展,使 CUDA 内核能够直接在 GPU 上创建新工作并与新工作同步。在程序中需要的任何位置动态创建并行性提供了令人兴奋的新功能。 直接从 GPU 创建工作的能力可以减少在主机和设备之间传输执行控制和数据的需要,因为现在可以通过在设备上执行的线程在运行时做...

(which is equivalent to__host__decoration, when usingnvcc). This doesn’t take into account CUDA Dynamic Parallelism, and possibly other advanced topics (CUDA Driver API, other launch methods such as CG, decorating a function with both__host__and__device__etc.), but t...
By comparison with host launch, device launch latency stays almost constant regardless of how much parallelism is in the graph. Conclusion CUDA device graph launch offers a performant way to enable dynamic control flow within CUDA kernels. While the example presented in this post provides a means ...
Figure 1. Cooperative Groups extends the CUDA programming model to provide flexible, dynamic grouping of threads. Historically, the CUDA programming model has provided a single, simple construct for synchronizing cooperating threads: a barrier across all threads of a thread block, as implemented with ...
I’m trying to implement a dynamic parallelism programming. However, when I compile the code on VS 2008, I got an fatal error which told me Unresolved extern function ‘cudaGetParameterBuffer’. I went through the dynamic parallelism guide and found that it’s about the PTX....
