I'm a CUDA learning student and I'm trying to write a CUDA algorithm for counting sort:
__global__ void kernelCountingSort(int *array, int dim_array, int *counts) {
// define index
int i = blo...

Can I reduce size of array in CUDA
I have allocated memory for 3d array using cudaMalloc3D - after execution of first kernel I established that I do not need part of it.
For example in pseudo code :
A = [100,100,100]
kernel()// data of...
