6.32. Profiler Control
This section describes the profiler control functions of the CUDA runtime application programming interface.
Functions
- __host__ cudaError_t cudaProfilerStart ( void )
- Enable profiling.
- __host__ cudaError_t cudaProfilerStop ( void )
- Disable profiling.
Functions
- __host__ cudaError_t cudaProfilerStart ( void )
-
Enable profiling.
Returns
Description
Enables profile collection by the active profiling tool for the current context. If profiling is already enabled, then cudaProfilerStart() has no effect.
cudaProfilerStart and cudaProfilerStop APIs are used to programmatically control the profiling granularity by allowing profiling to be done only on selective pieces of code.
Note:Note that this function may also return error codes from previous, asynchronous launches.

Returns
Description
Disables profile collection by the active profiling tool for the current context. If profiling is already disabled, then cudaProfilerStop() has no effect.
