It seems that WinML inference duration is correlated with the frequency with which it is called. The more frequent called the faster it is.
This repository contains a simple application which calls in a loop the WinML-based inference with various sleep times between iterations (0ms, 50ms, 100ms, 150ms, 200ms) and records the computed durations in a text file (winml_durations.txt). The ONNX model shall be provided as a first command line argument. The model's input is randomly generated, the output is retrieved and ignored. The application at startup enumerates available GPU devices in order to determine whether inference should be run on GPU (DirectX) or CPU (default), if there is no GPU device available. There is also a simple python script visualize_durations.py visualizing the collected durations.
- Open Visual Studio and load the winml_inference_time.sln solution.
- Build the solution in the
Releasemode for your architecture - Run the generated
winml_inference_time.exeproviding path to the ONNX model as the command line argument, for instance use the yolov2-coco-9.onnx model, i.e.:
$ ./x64/Release/winml_inference_time.exe ~/Downloads/yolov2-coco-9.onnx
Using model C:/Users/tomaszmi/Downloads/yolov2-coco-9.onnx
