//****************************************************************************
// Because dynamically sized shared memory arrays are declared "extern",
// we can't templatize them directly. To get around this, we declare a
// simple wrapper struct that will declare the extern array with a different
// name depending on the type. This avoids compiler errors about duplicate
// definitions.
//
// To use dynamically allocated shared memory in a templatized __global__ or
// __device__ function, just replace code like this:
// template<class T>
// __global__ void
// foo( T* g_idata, T* g_odata)
// {
// // Shared mem size is determined by the host app at run time
// extern __shared__ T sdata[];
// ...
// x = sdata[i];
// sdata[i] = x;
// ...
// }
//
// With this:
// template<class T>
// __global__ void
// foo( T* g_idata, T* g_odata)
// {
// // Shared mem size is determined by the host app at run time
// SharedMemory<T> sdata;
// ...
// x = sdata[i];
// sdata[i] = x;
// ...
// }
//****************************************************************************
// This is the un-specialized struct. Note that we prevent instantiation of
// this struct by making it abstract (i.e. with pure virtual methods).
template <typename T> struct SharedMemory
{
// Ensure that we won't compile any un-specialized types
virtual __device__ T &operator*() = 0;
virtual __device__ T &operator[](int i) = 0;
