It could even actively force suitable alignment by placing the object in shared memory appropriately, but I don’t have evidence that this is occurring.

WebApr 4, 2011 · CUDA supports dynamic shared memory allocation. If you define the kernel like this: __global__ void Kernel (const int count) { extern __shared__ int a []; } and then pass the number of bytes required as the the third argument of the kernel launch Kernel<<< gridDim, blockDim, a_size >>> (count) then it can be sized at run time. WebMay 27, 2015 · I have tested the first code that you have posted. When the mode is 4 byte, there is a conflict. When the mode is 8 byte, don’t. But it is similar to a race codition, because if i make a __synchronize() between the two memory access, the are no conflicts in both modalities. I do some studies on the shared memory conflicts.
