Description
Add onnxruntime/test/run_benchmark.py helper script to repeat benchmark runs until a target coefficient of variance is reached. It works with Google Benchmark programs like
onnxruntime_mlas_benchmark
.Motivation and Context
Sometimes there is variability in benchmark run results. This automates the repeated running needed to get results that are stable enough.
