Please refer to https://dlio-benchmark.readthedocs.io for full user documentation. + +## Overview + +DLIO is an I/O benchmark for Deep Learning. DLIO is aimed at emulating the I/O behavior of various deep learning applications. The benchmark is delivered as an executable that can be configured for various I/O patterns. It uses a modular design to incorporate more data loaders, data formats, datasets, and configuration parameters. It emulates modern deep learning applications using Benchmark Runner, Data Generator, Format Handler, and I/O Profiler modules. + +## Installation and running DLIO +### Bare metal installation + +```bash +git clone https://github.com/argonne-lcf/dlio_benchmark +cd dlio_benchmark/ +pip install . +dlio_benchmark ++workload.workflow.generate_data=True +``` + +### Bare metal installation with profiler + +```bash +git clone https://github.com/argonne-lcf/dlio_benchmark +cd dlio_benchmark/ +pip install .[pydftracer] +``` + +## Container +```bash +git clone https://github.com/argonne-lcf/dlio_benchmark +cd dlio_benchmark/ +docker build -t dlio . +docker run -t dlio dlio_benchmark ++workload.workflow.generate_data=True +``` + +You can also pull rebuilt container from docker hub (might not reflect the most recent change of the code): +```bash +docker pull docker.io/zhenghh04/dlio:latest +docker run -t docker.io/zhenghh04/dlio:latest dlio_benchmark ++workload.workflow.generate_data=True +``` +If your running on a different architecture, refer to the Dockerfile to build the dlio_benchmark container from scratch. + +One can also run interactively inside the container +```bash +docker run -t docker.io/zhenghh04/dlio:latest /bin/bash +root@30358dd47935:/workspace/dlio$ dlio_benchmark ++workload.workflow.generate_data=True +``` + +## PowerPC +PowerPC requires installation through anaconda. +```bash +# Setup required channels +conda config --prepend channels https://public.dhe.ibm.com/ibmdl/export/pub/software/server/ibm-ai/conda/ + +# create and activate environment +conda env create --prefix ./dlio_env_ppc --file environment-ppc.yaml --force +conda activate ./dlio_env_ppc +# install other dependencies +python -m pip install . +``` + +## Lassen, LLNL +For specific instructions on how to install and run the benchmark on Lassen please refer to: [Install Lassen](https://dlio-benchmark.readthedocs.io/en/latest/instruction_lassen.html) + +## Running the benchmark + +A DLIO run is split in 3 phases: +- Generate synthetic data that DLIO will use +- Run the benchmark using the previously generated data +- Post-process the results to generate a report + +The configurations of a workload can be specified through a yaml file. Examples of yaml files can be found in [dlio_benchmark/configs/workload/](./dlio_benchmark/configs/workload). + +One can specify the workload through the ```workload=``` option on the command line. Specific configuration fields can then be overridden following the ```hydra``` framework convention (e.g. ```++workload.framework=tensorflow```). + +First, generate the data + ```bash + mpirun -np 8 dlio_benchmark workload=unet3d ++workload.workflow.generate_data=True ++workload.workflow.train=False + ``` +If possible, one can flush the filesystem caches in order to properly capture device I/O + ```bash + sudo sync && echo 3 | sudo tee /proc/sys/vm/drop_caches + ``` +Finally, run the benchmark + ```bash + mpirun -np 8 dlio_benchmark workload=unet3d + ``` +Finally, run the benchmark with Tracer + ```bash + export DFTRACER_ENABLE=1 + export DFTRACER_INC_METADATA=1 + mpirun -np 8 dlio_benchmark workload=unet3d + ``` + +All the outputs will be stored in ```hydra_log/unet3d/$DATE-$TIME``` folder. To post process the data, one can do +```bash +dlio_postprocessor --output-folder hydra_log/unet3d/$DATE-$TIME +``` +This will generate ```DLIO_$model_report.txt``` in the output folder. + +## Workload YAML configuration file +Workload characteristics are specified by a YAML configuration file. Below is an example of a YAML file for the UNet3D workload which is used for 3D image segmentation. + +``` +# contents of unet3d.yaml +model: + name: unet3d + model_size: 499153191 + +framework: pytorch + +workflow: + generate_data: False + train: True + checkpoint: True + +dataset: + data_folder: data/unet3d/ + format: npz + num_files_train: 168 + num_samples_per_file: 1 + record_length_bytes: 146600628 + record_length_bytes_stdev: 68341808 + record_length_bytes_resize: 2097152 + +reader: + data_loader: pytorch + batch_size: 4 + read_threads: 4 + file_shuffle: seed + sample_shuffle: seed + +train: + epochs: 5 + computation_time: 1.3604 + +checkpoint: + checkpoint_folder: checkpoints/unet3d + checkpoint_after_epoch: 5 + epochs_between_checkpoints: 2 +``` + +The full list of configurations can be found in: https://argonne-lcf.github.io/dlio_benchmark/config.html + +The YAML file is loaded through hydra (https://hydra.cc/). The default setting are overridden by the configurations loaded from the YAML file. One can override the configuration through command line (https://hydra.cc/docs/advanced/override_grammar/basic/). + +## Current Limitations and Future Work + +* DLIO currently assumes the samples to always be 2D images, even though one can set the size of each sample through ```--record_length```. We expect the shape of the sample to have minimal impact to the I/O itself. This yet to be validated for case by case perspective. We plan to add option to allow specifying the shape of the sample. + +* We assume the data/label pairs are stored in the same file. Storing data and labels in separate files will be supported in future. + +* File format support: we only support tfrecord, hdf5, npz, csv, jpg, jpeg formats. Other data formats can be extended. + +* Data Loader support: we support reading datasets using TensorFlow tf.data data loader, PyTorch DataLoader, and a set of custom data readers implemented in ./reader. For TensorFlow tf.data data loader, PyTorch DataLoader + - We have complete support for tfrecord format in TensorFlow data loader. + - For npz, jpg, jpeg, hdf5, we currently only support one sample per file case. In other words, each sample is stored in an independent file. Multiple samples per file case will be supported in future. + +## How to contribute +We welcome contributions from the community to the benchmark code. Specifically, we welcome contribution in the following aspects: +General new features needed including: + +* support for new workloads: if you think that your workload(s) would be interested to the public, and would like to provide the yaml file to be included in the repo, please submit an issue. +* support for new data loaders, such as DALI loader, MxNet loader, etc +* support for new frameworks, such as MxNet +* support for noval file systems or storage, such as AWS S3. +* support for loading new data formats. + +If you would like to contribute, please submit an issue to https://github.com/argonne-lcf/dlio_benchmark/issues, and contact ALCF DLIO team, Huihuo Zheng at huihuo.zheng@anl.gov + +## Citation and Reference +The original CCGrid'21 paper describes the design and implementation of DLIO code.

Most of the options are essentially the same with the actual workload, such as ``framework``, ``reader``, and many options in ``train``, ``evaluation``, such as ``epochs``. The main work involved is to find out the dataset information and the computation time. For the former, one can to check the original dataset to find out the number of files for training, how many samples per file, and the sample size, data format, etc. For the latter, one has to run the actual workload to find out the comptuation time per training step. One might have to add timing stamp before and after the training step. + +The YAML files are stored in the `workload`_ folder. +It then can be loaded by ```dlio_benchmark``` through hydra (https://hydra.cc/). This will override the default settings. One can override the configurations through command line (https://hydra.cc/docs/advanced/override_grammar/basic/). + +.. _workload: https://github.com/argonne-lcf/dlio_benchmark/tree/main/dlio_benchmark/configs/workload + + +Environment variables +============================================ +There are a few environment variables that controls and logging and profiling information. + +.. list-table:: + :widths: 15 10 30 + :header-rows: 1 + + * - Variable name + - Default + - Description + * - DLIO_LOG_LEVEL + - warning + - Specifying the loging level [error|warning|info|debug].

Its application spans diverse scientific domains, including cosmology, particle physics, computer vision, fusion, and astrophysics. However, the success of deep learning algorithms is contingent upon substantial volumes and varieties of big data for accurate neural network training, thereby posing a significant challenge in large-scale distributed deep learning training due to potential I/O bottlenecks. + +The `DLIO`` benchmark aims to meticulously represent the data access patterns of deep learning workloads, allowing accurate emulation of I/O behavior during training. By leveraging `DLIO`, application developers and system software architects can pinpoint potential I/O bottlenecks and guide optimizations to enhance performance. Storage hardware vendors can also utilize the DLIO benchmark as a guide in designing storage and file systems tailored for deep learning applications. + +High-level Design +======================= +The standard AI training process entails transferring datasets from storage to host RAM, then forwarding them to accelerators for training. Data is loaded in batches concurrently through multiple threads while accelerators execute training. After processing each batch, the accelerator triggers a request to the host, prompting the loading of another batch from storage. This iterative cycle guarantees uninterrupted data processing, contributing to the efficiency of the training process. + + .. figure:: ./images/training.png + + Typical process of AI training. + +Based on the training process shown above, we can have following considerations in designing the benchmark: + +Firstly, the data loading process is independent of the specific computation happening in the accelerator. We therefore can replace the computation part with a sleep function of equivalent duration, and still produce the same the I/O pattern. This is demonstrated with the UNet3D workload shown below. We replace the computation with a sleep of different durations corresponding to the training time in Nvidia A100, V100, and P100 GPUs, we were able to generate the I/O timeline of the real workload running on different GPUs. Replacing the training part with a sleep function eliminate the needs of actual accelerators to perform the I/O benchmark, which significantly reduces the cost and complexity of benchmarking. It also allows us to simulate the I/O pattern for different types of accelerators easily by simply changing the sleep time accordingly. + + .. figure:: ./images/validation.png + + Upper panel: I/O timeline on A100, V100, P100; Lower panel: I/O timeline on Skylake with training replaced by sleep of different durations equal to the actual training time on A100, V100 and P100 respectively. + + +Secondly, the I/O process is indifferent to the actual values of the data. As long as the number of files, number of samples per file, size of each sample, batch size, and format are the same, the I/O behavior should be similar regardless of the details of each sample. This allows us to use synthetic data for benchmarking and still get the similar I/O behavior. This eliminates the need of downloading the original datasets for each workload which is a rather cumbersome task. + +Third, we will adopt built-in framework data loaders, such as tf.data, torch DataLoader, and Dali data loader, to allow DLIO to simulate advanced optimization features like pipeline, prefetching, and multithreaded data loading. + +With the above considerations, we design our benchmark using a modular design artitecture, which consists of modules like +**Benchmark Runner**, **Data Generator**, **Format Handler**, and **I/O Profiler**. These modules utilize state-of-the-art design patterns to build a transparent and extensible framework. + +1) **Accurate**: `DLIO` should be an accurate representation of +selected deep learning applications. It should +incorporate all the I/O behavior seen in various configurations of applications, + and act as a mini-application that can precisely replay the I/O behavior. + +2) **Configurable**: `DLIO` should be easily configurable for +different scenarios required by the user. These include +features such as different ratio-of-computation to I/O, multi +threading for I/O, data operators (e.g., decoding, shuffling, +prefetch, and batching), and mechanism to feed data into training. + +3) **Extensible**: `DLIO` benchmark should allow adding +custom data directories and enable easy extensions to the +benchmark to incorporate different data formats, data loaders +or data generation algorithms. +These changes should not affect the basic benchmark operations. + +'''''''''''''''''''' +`DLIO` Code Modules +'''''''''''''''''''' +Below shows the modules of the `DLIO` code. + +.. image:: images/dlio.png + +* **Configuration Manager**: the user specifies a YAML file which represents the characteristics of a real workload. The configuration manager will load the configuration into `DLIO`. + +* **Format Handler**: Format Handler will handle the data read and write for specific data format. + +* **Data Generator**: this is for generating synthetic datasets. This eliminates the dependence on real dataset which is typically difficult to get. `DLIO` can generate synthetic data in different formats, different organization and layouts on the storage, such as: + + * Single shared file in which the entire datasets is stored in one file. + * One samples per file + * Multiple samples per file + * Files putting in a single folder. + * Files putting in many subfolders. + +* **Benchmark Runner**: this is for performing the whole benchmarking process, including data generation, training, evaluation, checkpointing, profiling, etc. + +''''''''''''''''''''''' +Benchmark Execution +''''''''''''''''''''''' +**Configuration**: The YAML configure file is first parsed and extracted into configurations for the benchmark. The extracted configurations are passed to the Configuration Manager, which is first initialized with default benchmark values and then updates itself with the incoming configurations. At this stage, incompatible/incorrect configurations would be thrown as error back to the users. A complete instruction on how to prepare the YAML file can be found in :ref:`yaml`. + +**Data generation**: Once the configurations are validated and applied, the benchmark runner is invoked. The runner initializes prepared data (if needed) and then starts the profiling session. + +**Simulation**: Once the session has started successfully, the benchmark Run() is invoked, which runs the benchmark. In the run phase, we run the benchmark for multiple epochs. During each epoch, the whole data is read once using n steps. During an epoch, checkpoint operations are performed every c steps as well. + +Additionally, an inter-step computation is performed to emulate computation (through a sleep function) and I/O phases by deep learning application. Replacing computaiton with sleep allows the user to perform the benchmark in a acclerator absence environement. Different accelerators will have different amounts of computation time. + +Finally, once the benchmark run finishes, the finalize is called, which stops the profiler, saves its results, and exits the benchmark. + +**Post processing**: One can then use the post processing script to process the logs to produce a high level summary of the I/O performance. + diff --git a/dlio_benchmark/docs/source/profiling.rst b/dlio_benchmark/docs/source/profiling.rst new file mode 100644 index 00000000..37df7d7d --- /dev/null +++ b/dlio_benchmark/docs/source/profiling.rst @@ -0,0 +1,308 @@ +.. _profiling: + +Profiling +========================== +We have a built in support for iostat and DFTracer for I/O profiling.

Handle endpoint failures gracefully (s3dlio only) + +**Backend Support:** + +| Backend | Native Multi-Endpoint | MPI Rank-Based | Load Balancing | +|---------|----------------------|----------------|----------------| +| **s3dlio** | โœ… Yes | โœ… Yes | Round-robin, Least-connections | +| **minio** | โŒ No | โœ… Yes | Round-robin (via MPI rank) | +| **s3torchconnector** | โŒ No | โœ… Yes | Round-robin (via MPI rank) | + +**Key Differences:** +- **s3dlio**: Uses native `MultiEndpointStore` with true load balancing across endpoints +- **minio/s3torch**: Each MPI rank selects one endpoint (round-robin), no per-request balancing + +**Use cases**: +- Scale beyond single endpoint bandwidth +- Distribute load across multiple storage nodes +- High-availability configurations + +### Configuration Methods + +**Option 1: Comma-separated list** +```bash +export

+./quickstart_demo.sh +``` + +### MPI Distributed Mode + +For distributed training with MPI, each rank automatically selects a different endpoint: + +**All backends (s3dlio, minio, s3torchconnector):** +```bash +# Each of 8 ranks will use a different endpoint (round-robin) +export S3_ENDPOINT_URIS='http://172.16.21.1:9000,http://172.16.21.2:9000,http://172.16.21.3:9000,http://172.16.21.4:9000' + +mpirun -np 8 python -m dlio_benchmark.main workload=unet3d_v100 + +# Rank 0 โ†’ endpoint 1 +# Rank 1 โ†’ endpoint 2 +# Rank 2 โ†’ endpoint 3 +# Rank 3 โ†’ endpoint 4 +# Rank 4 โ†’ endpoint 1 (wraps around) +# ... etc +``` + +**How it works:** +- **s3dlio**: Can use native MultiEndpointStore OR MPI rank selection (both work) +- **minio**: Uses MPI rank selection only (no native multi-endpoint) +- **s3torchconnector**: Uses MPI rank selection only (no native multi-endpoint) + +**For minio and s3torchconnector**, each rank: +1.
