# simpleOccupancy - simpleOccupancy
|
|
|
|
## Description
|
|
|
|
This sample demonstrates the basic usage of the CUDA occupancy calculator and occupancy-based launch configurator APIs by launching a kernel with the launch configurator, and measures the utilization difference against a manually configured launch.
