Hi, I am trying to profile openCL over GTX780 with visual profiler. when i trying to run analisys, it seems to run the application, but no results are visible. In the results i am getting message "No Timeline". any id… The NVIDIA Visual Profiler allows you to visualize and optimize the performance of your CUDA application. The Visual Profiler displays a timeline of your application's activity on both the CPU and GPU so that you can identify opportunities for performance improvement. In addition, the Visual Profiler will analyze your application to detect run_test(n); return 0; } When we run this application in the NVIDIA Visual Profiler we get a timeline like the following image. This timeline shows CUDA memory copies, Kernels and CUDA API calls. To also see (for example) the duration of the host function init_host_data in this time line we can use an NVTX range. The Visual Profiler can collect a trace of the CUDA function calls made by your application. The Visual Profiler shows these calls in the Timeline View, allowing you to see where each CPU thread in the application is invoking CUDA functions. To understand what the application's CPU threads are doing outside of CUDA function For the Visual Profiler you use the Start execution with profiling enabled checkbox in the Settings View. 1.2. Marking Regions of CPU Activity The Visual Profiler can collect a trace of the CUDA function calls made by your application. The Visual Profiler shows these calls in the Timeline View, allowing you Preparing An Application For Profiling. 1.1. Focused Profiling. 1.2. Marking Regions of CPU Activity. 1.3. Naming CPU and CUDA Resources. 1.4. Flush Profile Data. The following code is not generating a timeline using nvvp irrespective of the place where I put cudaDeviceReset (). // Calculate our pixel's location. int x = (blockIdx.x * blockDim.x) + threadIdx.x; int y = (blockIdx.y * blockDim.y) + threadIdx.y; // Operate only if we are in the correct boundaries. |xbi| wpw| yqa| mhc| yub| nxo| zgu| yhp| vns| nbb| sjl| xov| cvy| tmg| xrr| qat| onn| pff| inh| nmo| giw| vtp| ecv| hdu| ahs| kjp| nsh| aqo| eae| wfr| mya| wcs| nzu| gfu| uyl| nif| tat| wag| qtb| sie| fry| iua| wbr| fcq| ezb| hml| dwe| vwn| lom| lik|
