It seems you are missing a checkCudaErrors (cudaDeviceSynchronize ()); to make sure the kernel completed. My guess is that, after you do this, the poison kernel will effectively kill the context. My advise here would be to run compute-sanitizer to get an overview of all CUDA API errors. More information here.

WebApr 11, 2024 · Please verify that you are building a release build (full optimizations). The kernel does not have a side effect (e.g. write to memory) so this will compile to almost an empty kernel. In a debug build I see the image you have above and the stalls are from debug code generated to specify variable live ranges. – WebApr 14, 2024 · Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

WebJan 20, 2024 · CUDA global synchronization HOWTO. I try to create an algorithm that runs an elementwise update operation and a reduction in 10k iteration and about 1_000_000 times, so the kernel restarts (2-8us) are really expensive in this scenario. The algorithm is very simple but on GPU I need to sync all the calculations before the reduce_sum. WebOct 1, 2016 · There is memory fence and block synchronization for cuda kernels.
