.PP 
\\brief occupancy calculation functions of the CUDA runtime API (cuda_runtime_api.h)
.PP
This section describes the occupancy calculation functions of the CUDA runtime application programming interface.
.PP
Besides the occupancy calculator function (\fBcudaOccupancyMaxActiveBlocksPerMultiprocessor\fP), there are also C++ only occupancy-based launch configuration functions documented in \fBC++ API Routines\fP module.
