Reference implementations of inference benchmarks

MLPerf Inference Reference Implementations

This is a repository of reference implementations for the MLPerf inference benchmark suite.

Reference implementations are valid as only starting points for benchmark implementations. They are not fully optimized, and they are not intended to be used for "real" performance measurements of software frameworks or hardware platforms. The objective is for hardware and software vendors to take these reference implementations, optimize then, and submit them as optimized solutions to the MLPerf Inference call for submissions.

Preliminary release (v0.5)

MLPerf inference release is very much an "alpha" release -- it could be improved in many ways. The benchmark suite is still being developed and refined. Please see the suggestions section below to learn how to contribute. We anticipate a significant round of updates after the v0.5 call for submission finishes. Much of the input would be taken into account for v0.6.

Benchmarks

We provide reference implementations for each of the 5 benchmarks in the MLPerf inference suite:

Area	Task	Model	Dataset	Quality Target	Latency Constraint
Vision	Image classification	Resnet50-v1.5	ImageNet (224x224)	TBD	TBD
Vision	Image classification	MobileNets-v1 224	ImageNet (224x224)	TBD	TBD
Vision	Object detection	SSD-ResNet34	COCO (1200x1200)	TBD	TBD
Vision	Object detection	SSD-MobileNets-v1	COCO (300x300)	TBD	TBD
Language	Machine translation	GNMT	WMT16	TBD	TBD

Each reference implementation provides the following:

• Code that implements the model in at least one framework.
• A Dockerfile which can be used to run the benchmark in a container. The exception is GNMT.
• A script which downloads the appropriate dataset.
• A script which runs and times the model inference.
• Documentation on the dataset, model, and machine setup.

Running Benchmarks

You will need to install the LoadGen and download and install the datasets and models.

Load Generator

Please refer to README at under /loadgen directory to install LoadGen. Also see useful presentation material here.

Models

Vision

Please refer to README at https://github.com/mlperf/inference/tree/master/v0.5/classification_and_detection.

Language

Please refer to README at https://github.com/mlperf/inference/tree/master/v0.5/translation/gnmt/tensorflow

Test Setup

These benchmarks have been tested on the following machine configuration:

• Tested SW configurations:

  • Python 3
  • Cuda10.0, TF 1.14

• Tested HW configurations:

  • Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz with 12 threads (vCPUs) and one Titan XP
  • 64G DRAM
  • 200G Disk (recommmended)

So far, all models/scenarios except for SSD-resnet34 have been tested under the above hardware configuration.

Suggestions

We are still in the early stages of developing MLPerf, and we are looking for areas to improve, partners, and contributors.
