           CUoutput_mode outputMode)
           Initialize the profiling.

           Enable profiling.
       CUresult cuProfilerStop (void)
           Disable profiling.

Detailed Description

       \brief profiler control functions of the low-level CUDA driver API (cudaProfiler.h)

       This section describes the profiler control functions of the low-level CUDA driver
       application programming interface.

Function Documentation

   CUresult cuProfilerInitialize (const char * configFile, const char * outputFile, CUoutput_mode
       outputMode)
       Using this API user can initialize the CUDA profiler by specifying the configuration file,
       output file and output file format. This API is generally used to profile different set of
       counters by looping the kernel launch. The configFile parameter can be used to select
       profiling options including profiler counters. Refer to the 'Compute Command Line Profiler
       User Guide' for supported profiler options and counters.

       Limitation: The CUDA profiler cannot be initialized with this API if another profiling
       tool is already active, as indicated by the CUDA_ERROR_PROFILER_DISABLED return code.

       Typical usage of the profiling APIs is as follows:

       for each set of counters/options
        {
        cuProfilerInitialize(); //Initialize profiling, set the counters or options in the config
       file
        ...
        cuProfilerStart();
        // code to be profiled
        cuProfilerStop();
        ...
        cuProfilerStart();
        // code to be profiled
        cuProfilerStop();
        ...
        }

       Parameters:
           configFile - Name of the config file that lists the counters/options for profiling.
           outputFile - Name of the outputFile where the profiling results will be stored.
           outputMode - outputMode, can be CU_OUT_KEY_VALUE_PAIR or CU_OUT_CSV.

       Returns:
           CUDA_SUCCESS, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE,
           CUDA_ERROR_PROFILER_DISABLED

       Note:
           Note that this function may also return error codes from previous, asynchronous
           launches.

       See also:
           cuProfilerStart, cuProfilerStop, cudaProfilerInitialize

   CUresult cuProfilerStart (void)
       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.

       Returns:
           CUDA_SUCCESS, CUDA_ERROR_INVALID_CONTEXT

       Note:
           Note that this function may also return error codes from previous, asynchronous
           launches.

       See also:
           cuProfilerInitialize, cuProfilerStop, cudaProfilerStart

   CUresult cuProfilerStop (void)
       Disables profile collection by the active profiling tool for the current context. If
       profiling is already disabled, then cuProfilerStop() 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.

       Returns:
           CUDA_SUCCESS, CUDA_ERROR_INVALID_CONTEXT

       Note:
           Note that this function may also return error codes from previous, asynchronous
           launches.
