\brief Returns occupancy for a device function

Returns in \p *numBlocks the maximum number of active blocks per streaming multiprocessor for the device function.

\param numBlocks - Returned occupancy \param func - Kernel function for which occupancy is calculated \param blockSize - Block size the kernel is intended to be launched with \param dynamicSMemSize - Per-block dynamic shared memory usage intended, in bytes
