WebHowever, the compiler appears to "look at" the lambda in the host and the device compilation path (even though it ultimately only compiles for the device, as it is a device lambda). Now because of the #ifdef CUDA_ARCH , one path sees two implicit captures, X and N, while the other path sees no implicit captures as the lambda body is empty. Web6 Sep 2024 · When copying data from device to host, both iterators are passed as function parameters. 1. Which execution policy is picked here per default? thrust::host or thrust::device? After doing some benchmarks, I observe that passing thrust::device explicitly improves performance, compared to not passing an explicit parameter. 2.
