RAPIDS GPU-BDB

Disclaimer

gpu-bdb is derived from TPCx-BB. Any results based on gpu-bdb are considered unofficial results, and per TPC policy, cannot be compared against official TPCx-BB results.

Overview

The GPU Big Data Benchmark (gpu-bdb) is a RAPIDS library based benchmark for enterprises that includes 30 queries representing real-world ETL & ML workflows at various "scale factors": SF1000 is 1 TB of data, SF10000 is 10TB. Each “query” is in fact a model workflow that can include SQL, user-defined functions, careful sub-setting and aggregation, and machine learning.

Conda Environment Setup

We provide a conda environment definition specifying all RAPIDS dependencies needed to run our query implementations. To install and activate it:

CONDA_ENV="rapids-gpu-bdb"
conda env create --name $CONDA_ENV -f gpu-bdb/conda/rapids-gpu-bdb.yml
conda activate rapids-gpu-bdb

Installing RAPIDS bdb Tools

This repository includes a small local module containing utility functions for running the queries. You can install it with the following:

cd gpu-bdb/gpu_bdb
python -m pip install .

This will install a package named bdb-tools into your Conda environment. It should look like this:

conda list | grep bdb
bdb-tools                 0.2                      pypi_0    pypi

Note that this Conda environment needs to be replicated or installed manually on all nodes, which will allow starting one dask-cuda-worker per node.

NLP Query Setup

Queries 10, 18, and 19 depend on two static (negativeSentiment.txt, positiveSentiment.txt) files. As we cannot redistribute those files, you should download the tpcx-bb toolkit and extract them to your data directory on your shared filesystem:

jar xf bigbenchqueriesmr.jar
cp tpcx-bb1.3.1/distributions/Resources/io/bigdatabenchmark/v1/queries/q10/*.txt ${DATA_DIR}/sentiment_files/

For Query 27, we rely on spacy. To download the necessary language model after activating the Conda environment:

python -m spacy download en_core_web_sm

Starting Your Cluster

We use the dask-scheduler and dask-cuda-worker command line interfaces to start a Dask cluster. We provide a cluster_configuration directory with a bash script to help you set up an NVLink-enabled cluster using UCX.

Before running the script, you'll make changes specific to your environment.

In cluster_configuration/cluster-startup.sh:

- Update `GPU_BDB_HOME=...` to location on disk of this repo
- Update `CONDA_ENV_PATH=...` to refer to your conda environment path.
- Update `CONDA_ENV_NAME=...` to refer to the name of the conda environment you created, perhaps using the `yml` files provided in this repository.
- Update `INTERFACE=...` to refer to the relevant network interface present on your cluster.
- Update `CLUSTER_MODE="TCP"` to refer to your communication method, either "TCP" or "NVLINK". You can also configure this as an environment variable.
- You may also need to change the `LOCAL_DIRECTORY` and `WORKER_DIR` depending on your filesystem. Make sure that these point to a location to which you have write access and that `LOCAL_DIRECTORY` is accessible from all nodes.

To start up the cluster on your scheduler node, please run the following from gpu_bdb/cluster_configuration/. This will spin up a scheduler and one Dask worker per GPU.

DASK_JIT_UNSPILL=True CLUSTER_MODE=NVLINK bash cluster-startup.sh SCHEDULER

Note: Don't use DASK_JIT_UNSPILL when running BlazingSQL queries.

Then run the following on every other node from gpu_bdb/cluster_configuration/.

bash cluster-startup.sh

This will spin up one Dask worker per GPU. If you are running on a single node, you will only need to run bash cluster-startup.sh SCHEDULER.

If you are using a Slurm cluster, please adapt the example Slurm setup in gpu_bdb/benchmark_runner/slurm/ which uses gpu_bdb/cluster_configuration/cluster-startup-slurm.sh.

Running the Queries

To run a query, starting from the repository root, go to the query specific subdirectory. For example, to run q07:

cd gpu_bdb/queries/q07/

The queries assume that they can attach to a running Dask cluster. Cluster address and other benchmark configuration lives in a yaml file (gpu_bdb/benchmark_runner/becnhmark_config.yaml). You will need to fill this out as appropriate if you are not using the Slurm cluster configuration.

conda activate rapids-gpu-bdb
python gpu_bdb_query_07.py --config_file=../../benchmark_runner/benchmark_config.yaml

To NSYS profile a gpu-bdb query, change start_local_cluster in benchmark_config.yaml to True and run:

nsys profile -t cuda,nvtx python gpu_bdb_query_07_dask_sql.py --config_file=../../benchmark_runner/benchmark_config.yaml

Note: There is no need to start workers with cluster-startup.sh as there is a LocalCUDACluster being started in attach_to_cluster API.

Performance Tracking

This repository includes optional performance-tracking automation using Google Sheets. To enable logging query runtimes, on the client node:

export GOOGLE_SHEETS_CREDENTIALS_PATH=<path to creds.json>

Then configure the --sheet and --tab arguments in benchmark_config.yaml.

Running all of the Queries

The included benchmark_runner.py script will run all queries sequentially. Configuration for this type of end-to-end run is specified in benchmark_runner/benchmark_config.yaml.

To run all queries, cd to gpu_bdb/ and:

python benchmark_runner.py --config_file benchmark_runner/benchmark_config.yaml

By default, this will run each Dask query five times, and, if BlazingSQL queries are enabled in benchmark_config.yaml, each BlazingSQL query five times. You can control the number of repeats by changing the N_REPEATS variable in the script.

BlazingSQL

BlazingSQL implementations of all queries are included. BlazingSQL currently supports communication via TCP. To run BlazingSQL queries, please follow the instructions above to create a cluster using CLUSTER_MODE=TCP.

Data Generation

The RAPIDS queries expect Apache Parquet formatted data. We provide a script which can be used to convert bigBench dataGen's raw CSV files to optimally sized Parquet partitions.
