This blog is a guide for running the MLPerf inference v1.1 benchmark. Information about how to run the MLPerf inference v1.1 benchmark is available online at different locations. This blog provides all the steps in one place.
MLPerf is a benchmarking suite that measures the performance of Machine Learning (ML) workloads. It focuses on the most important aspects of the ML life cycle: training and inference. For more information, see Introduction to MLPerf™ Inference v1.1 Performance with Dell EMC Servers.
This blog focuses on inference setup and describes the steps to run closed data center MLPerf inference v1.1 tests on Dell Technologies servers with NVIDIA GPUs. It enables you to run the tests and reproduce the results that we observed in our HPC & AI Innovation Lab. For details about the hardware and the software stack for different systems in the benchmark, see this list of systems.
The MLPerf inference v1.1 suite contains the following benchmarks:
- Resnet50
- SSD-Resnet34
- BERT
- DLRM
- RNN-T
- 3D U-Net
Note: The BERT, DLRM, and 3D U-Net models have 99 percent (default accuracy) and 99.9 percent (high accuracy) targets.
This blog describes the steps to run all these benchmarks.
1 Getting started
A system under test consists of a defined set of hardware and software resources that will be measured for performance. The hardware resources may include processors, accelerators, memories, disks, and interconnect. The software resources may include an operating system, compilers, libraries, and drivers that significantly influence the running time of a benchmark. In this case, the system on which you clone the MLPerf repository and run the benchmark is known as the system under test (SUT).
For storage, SSD RAID or local NVMe drives are acceptable for running all the subtests without any penalty. Inference does not have strict requirements for fast-parallel storage. However, the BeeGFS or Lustre file system, the PixStor storage solution, and so on help make multiple copies of large datasets.
2 Prerequisites
Prerequisites for running the MLPerf inference v1.1 tests include:
- An x86_64 Dell EMC systems
- Docker installed with the NVIDIA runtime hook
- Ampere-based NVIDIA GPUs (Turing GPUs have legacy support but are no longer maintained for optimizations.)
- NVIDIA driver version 470.xx or later
- As of inference v1.0, ECC turned ON
Set ECC to on,run the following command:sudo nvidia-smi --ecc-config=1
Preparing to run the MLPerf inference v1.1
Before you can run the MLPerf inference v1.1 tests, perform the following tasks to prepare your environment.
3.1 Clone the MLPerf repository
- Clone the repository to your home directory or another acceptable path:
cd - git clone https://github.com/mlperf/inference_results_v1.1
- Go to the closed/DellEMC directory:
cd inference_results_v1.1/closed/DellEMC
- Create a “scratch” directory with at least 3 TB of space in which to store the models, datasets, preprocessed data, and so on:
mkdir scratch
- Export the absolute path for $MLPERF_SCRATCH_PATH with the scratch directory:
export MLPERF_SCRATCH_PATH=/home/user/inference_results_v1.1/closed/DellEMC/scratch
3.2 Set up the configuration file
The closed/DellEMC/configs directory includes an __init__.py file that lists configurations for different Dell EMC servers that were systems in the MLPerf Inference v1.1 benchmark. If necessary, modify the configs/<benchmark>/<Scenario>/__init__.py file to include the system that will run the benchmark.
Note: If your system is already present in the configuration file, there is no need to add another configuration.
In the configs/<benchmark>/<Scenario>/__init__.py file, select a similar configuration and modify it based on the current system, matching the number and type of GPUs in your system.
For this blog, we used a Dell EMC PowerEdge R7525 server with a one-A100 GPU as the example. We chose R7525_A100_PCIE_40GBx1 as the name for this new system. Because the R7525_A100_PCIE_40GBx1 system is not already in the list of systems, we added the R7525_A100-PCIe-40GBx1 configuration.
Because the R7525_A100_PCIE_40GBx3 reference system is the most similar, we modified that configuration and picked Resnet50 Server as the example benchmark.
The following example shows the reference configuration for three GPUs for the Resnet50 Server benchmark in the configs/resnet50/Server/__init__.py file:
@ConfigRegistry.register(HarnessType.LWIS, AccuracyTarget.k_99, PowerSetting.MaxP) class R7525_A100_PCIE_40GBx3(BenchmarkConfiguration): system = System("R7525_A100-PCIE-40GB", Architecture.Ampere, 3) active_sms = 100 input_dtype = "int8" input_format = "linear" map_path = "data_maps/<dataset_name>/val_map.txt" precision = "int8" tensor_path = "${PREPROCESSED_DATA_DIR}/<dataset_name>/ResNet50/int8_linear" use_deque_limit = True deque_timeout_usec = 5742 gpu_batch_size = 205 gpu_copy_streams = 11 gpu_inference_streams = 9 server_target_qps = 91250 use_cuda_thread_per_device = True use_graphs = True scenario = Scenario.Server benchmark = Benchmark.ResNet50 start_from_device=True
This example shows the modified configuration for one GPU:
@ConfigRegistry.register(HarnessType.LWIS, AccuracyTarget.k_99, PowerSetting.MaxP) class R7525_A100_PCIE_40GBx1(BenchmarkConfiguration): system = System("R7525_A100-PCIE-40GB", Architecture.Ampere, 1) active_sms = 100 input_dtype = "int8" input_format = "linear" map_path = "data_maps/<dataset_name>/val_map.txt" precision = "int8" tensor_path = "${PREPROCESSED_DATA_DIR}/<dataset_name>/ResNet50/int8_linear" use_deque_limit = True deque_timeout_usec = 5742 gpu_batch_size = 205 gpu_copy_streams = 11 gpu_inference_streams = 9 server_target_qps = 30400 use_cuda_thread_per_device = True use_graphs = True scenario = Scenario.Server benchmark = Benchmark.ResNet50 start_from_device=True
We modified the queries per second (QPS) parameter (server_target_qps) to match the number of GPUs. The server_target_qps parameter is linearly scalable, therefore the QPS = number of GPUs x QPS per GPU.
The modified parameter is server_target_qps set to 30400 in accordance with one GPU performance expectation.
3.3 Add the new system
After you add the new system to the __init__.py file as shown in the preceding example, add the new system to the list of available systems. The list of available systems is in the code/common/system_list.py file. This entry informs the benchmark that a new system exists and ensures that the benchmark selects the correct configuration.
Note: If your system is already added, there is no need to add it to the code/common/system_list.py file.
Add the new system to the list of available systems in the code/common/system_list.py file.
At the end of the file, there is a class called KnownSystems. This class defines a list of SystemClass objects that describe supported systems as shown in the following example:
SystemClass(<system ID>, [<list of names reported by nvidia-smi>], [<known PCI IDs of this system>], <architecture>, [list of known supported gpu counts>])
Where:
- For <system ID>, enter the system ID with which you want to identify this system.
- For <list of names reported by nvidia-smi>, run the nvidia-smi -L command and use the name that is returned.
- For <known PCI IDs of this system>, run the following command:
$ CUDA_VISIBLE_ORDER=PCI_BUS_ID nvidia-smi --query-gpu=gpu_name,pci.device_id --format=csv
name, pci.device_id
A100-PCIE-40GB, 0x20F110DE
---
This pci.device_id field is in the 0x<PCI ID>10DE format, where 10DE is the NVIDIA PCI vendor ID. Use the four hexadecimal digits between 0x and 10DE as your PCI ID for the system. In this case, it is 20F1.
- For <architecture>, use the architecture Enum, which is at the top of the file. In this case, A100 is Ampere architecture.
- For the <list of known GPU counts>, enter the number of GPUs of the systems you want to support (that is, [1,2,4] if you want to support 1x, 2x, and 4x GPU variants of this system.). Because we already have a 3x variant in the system_list.py file, we simply need to include the number 1 as an additional entry.
Note: Because a configuration is already present for the PowerEdge R7525 server, we added the number 1 for our configuration, as shown in the following example. If your system does not exist in the system_list.py file, add the entire configuration and not just the number.
class KnownSystems: """ Global List of supported systems """ # before the addition of 1 - this config only supports R7525_A100-PCIE-40GB x3 # R7525_A100_PCIE_40GB= SystemClass("R7525_A100-PCIE-40GB", ["A100-PCIE-40GB"], ["20F1"], Architecture.Ampere, [3]) # after the addition – this config now supports R7525_A100-PCIE-40GB x1 and R7525_A100-PCIE-40GB x3 versions. R7525_A100_PCIE_40GB= SystemClass("R7525_A100-PCIE-40GB", ["A100-PCIE-40GB ["20F1"], Architecture.Ampere, [1, 3]) DSS8440_A100_PCIE_80GB = SystemClass("DSS8440_A100-PCIE-80GB", ["A100-PCIE-80GB"], ["20B5"], Architecture.Ampere, [10]) DSS8440_A30 = SystemClass("DSS8440_A30", ["A30"], ["20B7"], Architecture.Ampere, [8], valid_mig_slices=[MIGSlice(1, 6), MIGSlice(2, 12), MIGSlice(4, 24)]) R750xa_A100_PCIE_40GB = SystemClass("R750xa_A100-PCIE-40GB", ["A100-PCIE-40GB"], ["20F1"], Architecture.Ampere, [4]) R750xa_A100_PCIE_80GB = SystemClass("R750xa_A100-PCIE-80GB", ["A100-PCIE-80GB"], ["20B5"], Architecture.Ampere, [4],valid_mig_slices=[MIGSlice(1, 10), MIGSlice(2, 20), MIGSlice(3, 40)]) ----
Note: You must provide different configurations in the configs/resnet50/Server/__init__.py file for the x1 variant and x3 variant. In the preceding example, the R7525_A100-PCIE-40GBx3 configuration is different from the R7525_A100-PCIE-40GBx1 configuration.
3.4 Build the Docker image and required libraries
Build the Docker image and then launch an interactive container. Then, in the interactive container, build the required libraries for inferencing.
- To build the Docker image, run the make prebuild command inside the closed/DellEMC folder:
Command:
make prebuildThe following example shows sample output:
Launching Docker session nvidia-docker run --rm -it -w /work \ -v /home/user/article_inference_v1.1/closed/DellEMC:/work -v /home/user:/mnt//home/user \ --cap-add SYS_ADMIN \ -e NVIDIA_VISIBLE_DEVICES=0 \ --shm-size=32gb \ -v /etc/timezone:/etc/timezone:ro -v /etc/localtime:/etc/localtime:ro \ --security-opt apparmor=unconfined --security-opt seccomp=unconfined \ --name mlperf-inference-user -h mlperf-inference-user --add-host mlperf-inference-user:127.0.0.1 \ --user 1002:1002 --net host --device /dev/fuse \ -v =/home/user/inference_results_v1.0/closed/DellEMC/scratch:/home/user/inference_results_v1.1/closed/DellEMC/scratch \ -e MLPERF_SCRATCH_PATH=/home/user/inference_results_v1.0/closed/DellEMC/scratch \ -e HOST_HOSTNAME=node009 \ mlperf-inference:user
The Docker container is launched with all the necessary packages installed.
- Access the interactive terminal on the container.
- To build the required libraries for inferencing, run the make build command inside the interactive container:
Command
make build
The following example shows sample output:
(mlperf) user@mlperf-inference-user:/work$ make build ……. [ 26%] Linking CXX executable /work/build/bin/harness_default make[4]: Leaving directory '/work/build/harness' make[4]: Leaving directory '/work/build/harness' make[4]: Leaving directory '/work/build/harness' [ 36%] Built target harness_bert [ 50%] Built target harness_default [ 55%] Built target harness_dlrm make[4]: Leaving directory '/work/build/harness' [ 63%] Built target harness_rnnt make[4]: Leaving directory '/work/build/harness' [ 81%] Built target harness_triton make[4]: Leaving directory '/work/build/harness' [100%] Built target harness_triton_mig make[3]: Leaving directory '/work/build/harness' make[2]: Leaving directory '/work/build/harness' Finished building harness. make[1]: Leaving directory '/work' (mlperf) user@mlperf-inference-user:/work
The container in which you can run the benchmarks is built.
3.5 Download and preprocess validation data and models
To run the MLPerf inference v1.1, download datasets and models, and then preprocess them. MLPerf provides scripts that download the trained models. The scripts also download the dataset for benchmarks other than Resnet50, DLRM, and 3D U-Net.
For Resnet50, DLRM, and 3D U-Net, register for an account and then download the datasets manually:
- Resnet50—Download the most common image classification 2012 Validation set and extract the downloaded file to $MLPERF_SCRATCH_PATH/data/<dataset_name>/
(https://github.com/mlcommons/training/tree/master/image_classification). - DLRM—Download the Criteo Terabyte dataset and extract the downloaded file to $MLPERF_SCRATCH_PATH/data/criteo/
- 3D U-Net—Download the BraTS challenge data and extract the downloaded file to $MLPERF_SCRATCH_PATH/data/BraTS/MICCAI_BraTS_2019_Data_Training
Except for the Resnet50, DLRM, and 3D U-Net datasets, run the following commands to download all the models, datasets, and then preprocess them:
$ make download_model # Downloads models and saves to $MLPERF_SCRATCH_PATH/models $ make download_data # Downloads datasets and saves to $MLPERF_SCRATCH_PATH/data $ make preprocess_data # Preprocess data and saves to $MLPERF_SCRATCH_PATH/preprocessed_data
Note: These commands download all the datasets, which might not be required if the objective is to run one specific benchmark. To run a specific benchmark rather than all the benchmarks, see the following sections for information about the specific benchmark.

4 Running the benchmarks
After you have performed the preceding tasks to prepare your environment, run any of the benchmarks that are required for your tests.
The Resnet50, SSD-Resnet34, and RNN-T benchmarks have 99 percent (default accuracy) targets.
The BERT, DLRM, and 3D U-Net benchmarks have 99 percent (default accuracy) and 99.9 percent (high accuracy) targets. For information about running these benchmarks, see the Running high accuracy target benchmarks section below.
If you downloaded and preprocessed all the datasets (as shown in the previous section), there is no need to do so again. Skip the download and preprocessing steps in the procedures for the following benchmarks.
NVIDIA TensorRT is the inference engine for the backend. It includes a deep learning inference optimizer and runtime that delivers low latency and high throughput for deep learning applications.

- Extract the images to $MLPERF_SCRATCH_PATH/data/<dataset_name>/
- Run the following commands:
make download_model BENCHMARKS=resnet50 make preprocess_data BENCHMARKS=resnet50
- Generate the TensorRT engines:
# generates the TRT engines with the specified config. In this case it generates engine for both Offline and Server scenario make generate_engines RUN_ARGS="--benchmarks=resnet50 --scenarios=Offline,Server --config_ver=default"

6 Limitations and Best Practices for Running MLPerf
Note the following limitations and best practices:
- To build the engine and run the benchmark by using a single command, use the make run RUN_ARGS… shortcut. The shortcut is valid alternative to the make generate_engines … && make run_harness.. commands.
- Include the --fast flag in the RUN_ARGS command to test runs quickly by setting the run time to one minute. For example
make run_harness RUN_ARGS="–-fast --benchmarks=<bmname> --scenarios=<scenario> --config_ver=<cver> --test_mode=PerformanceOnly"
The benchmark runs for one minute instead of the default 10 minutes.
- If the server results are “INVALID”, reduce the server_target_qps for a Server scenario run. If the latency constraints are not met during the run, “INVALID” results are expected.
- If the results are “INVALID” for an Offline scenario run, then increase the offline_expected_qps. “INVALID” runs for the Offline scenario occurs when the system can deliver a significantly higher QPS than what is provided through the offline_expected_qps configuration.
- If the batch size changes, rebuild the engine.
- Only the BERT, DLRM, 3D-U-Net benchmarks support high accuracy targets.
- 3D-U-Net only has the Offline scenario.
- Triton Inference Server runs by passing triton and high_accuracy_triton for default and high_accuracy targets respectively inside the config_ver argument.
- When running a command with RUN_ARGS, be aware of the quotation marks. Errors can occur if you omit the quotation marks.
Conclusion
