Ray Train Benchmarks
|
|
====================
|
|
|
|
Below we document key performance benchmarks for common Ray Train tasks and workflows.
|
|

.. _pytorch_gpu_training_benchmark:

|
|
GPU image training
|
|
------------------
|
|
|
|
This task uses the TorchTrainer module to train different amounts of data
|
|
using a PyTorch ResNet model.
|
|
|
|
We test out the performance across different cluster sizes and data sizes.

|

|
|
|
|
.. note::
|
|
|
|
For multi-host distributed training, on AWS we need to ensure ec2 instances are in the same VPC and
|
|
all ports are open in the security group.

|
PyTorch training parity
|
|
-----------------------
|
|
|
|
This task checks the performance parity between native PyTorch Distributed and
|
|
Ray Train's distributed TorchTrainer.
|
|
|
|
We demonstrate that the performance is similar (within 2.5\%) between the two frameworks.
|
|
Performance may vary greatly across different model, hardware, and cluster configurations.
|
|
|
|
The reported times are for the raw training times. There is an unreported constant setup
|
|
overhead of a few seconds for both methods that is negligible for longer training runs.

TensorFlow training parity
|
|
--------------------------
|

|
|
This task checks the performance parity between native TensorFlow Distributed and

|
Ray Train's distributed TensorflowTrainer.
|
|
|
|
We demonstrate that the performance is similar (within 1\%) between the two frameworks.
|
|
Performance may vary greatly across different model, hardware, and cluster configurations.

The reported times are for the raw training times. There is an unreported constant setup
|
|
overhead of a few seconds for both methods that is negligible for longer training runs.
|
|
|
|
.. note:: The batch size and number of epochs is different for the GPU benchmark, resulting in a longer runtime.

XGBoost training

This task uses the XGBoostTrainer module to train on different sizes of data

with different amounts of parallelism to show near-linear scaling from distributed

data parallelism.

XGBoost parameters were kept as defaults for ``xgboost==1.7.6`` this task.
