This simple CUDA program demonstrates how to write a function that will execute on the GPU (aka "device"). The CPU, or "host", creates CUDA threads by calling special functions called "kernels". CUDA programs are C++ programs with additional syntax. To see how it works...
For any object (i.e, variable, array, union, struct, pointer or function) the unary address operator can be used to access the address of that object. Suppose that int i = 1; int *p = NULL; So then a statement p = &i;, copies the address of the variable i to the pointer p. I...
