Functions

__host__ ​cudaError_t cudaProfilerStart ( void )

Enable profiling.

Returns

cudaSuccess

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.
