Detailed Description

A simple CUDA timer class using CUDA events.

Measures the execution time of CUDA operations between calls to start_timer() and stop_timer().

Definition at line 132 of file cuda_utils.cuh.

Constructor & Destructor Documentation

CudaTimer()

CudaTimer::CudaTimer ( )

inline

Constructs the CudaTimer and creates CUDA events.

Definition at line 138 of file cuda_utils.cuh.

    {
        cudaEventCreate(&start);
        cudaEventCreate(&stop);
    }

~CudaTimer()

CudaTimer::~CudaTimer ( )

inline

Destroys the CUDA events.

Definition at line 147 of file cuda_utils.cuh.

    {
        cudaEventDestroy(start);
        cudaEventDestroy(stop);
    }

Member Function Documentation

start_timer()

void CudaTimer::start_timer ( )

inline

Records the start event in the default CUDA stream.

Definition at line 156 of file cuda_utils.cuh.

    {
        cudaEventRecord(start);
    }

stop_timer()

float CudaTimer::stop_timer ( )

inline

Records the stop event, synchronizes, and calculates elapsed time.

Returns

float The elapsed time in milliseconds between the last calls to start_timer() and stop_timer().

Definition at line 166 of file cuda_utils.cuh.

    {
        cudaEventRecord(stop);
        cudaEventSynchronize(stop); // Wait for the stop event to complete
        cudaEventElapsedTime(&time, start, stop); // Calculate time difference
        return time;
    }
