WebMar 9, 2013 · Device memory allocated statically or dynamically is not directly accessible (e.g. by dereferencing a pointer) from the host. It is necessary to access it via a cuda runtime API call like cudaMemset, or cudaMemcpy. The fact that they share the same address space (UVA) does not mean they can be accessed the same way. WebOct 19, 2015 · In CUDA function type qualifiers __device__ and __host__ can be used together in which case the function is compiled for both the host and the device. This allows to eliminate copy-paste. However, there is no such thing as __host__ __device__ variable. I'm looking for an elegant way to do something like this:

WebDec 5, 2012 · Memory copies from host to device of a memory block of 64 KB or less; Memory copies performed by functions that are suffixed with Async; Memory set function calls. This is all intentional of course, so that you can use the GPU and CPU simultaneously. WebJun 12, 2012 · For example, put the kernel that fills the location "0" and cudaMemcpy from that location back to host into stream 0, kernel that fills the location "1" and cudaMemcpy from "1" into stream 1, etc. What will happen then is that the GPU will overlap copying from "0" and executing "1". Check CUDA documentation, it's documented somewhere (in the ... WebJul 13, 2011 · I am trying to use cuda-gdb to check global device memory. It seems the values are all zero, even after cudaMemcpy. However, in the kernel, the values in the shared memory are good. Any idea? Does cuda-gdb even checks for global device memory at all. It seems host memory and device shared memory are fine.
