Functions

CUresult cuProfilerStart ( void )

Enable profiling.

Returns

CUDA_SUCCESS, CUDA_ERROR_INVALID_CONTEXT

Description

Enables profile collection by the active profiling tool for the current context. If profiling is already enabled, then cuProfilerStart() has no effect.

cuProfilerStart and cuProfilerStop 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.
