The RAPIDS Accelerator for Apache Spark provides a set of plugins for Apache Spark that leverage GPUs to accelerate processing via the RAPIDS libraries and UCX.
The chart above shows results from running ETL queries based off of the TPCxBB benchmark. These are not official results in any way. It uses a 10TB Dataset (scale factor 10,000), stored in parquet. The processing happened on a two node DGX-2 cluster. Each node has 96 CPU cores, 1.5TB host memory, 16 V100 GPUs, and 512 GB GPU memory.
To get started and try the plugin out use the getting started guide.
The SQL plugin tries to produce results that are bit for bit identical with Apache Spark. Operator compatibility is documented here
To get started tuning your job and get the most performance out of it please start with the tuning guide.
The plugin has a set of Spark configs that control its behavior and are documented here.
We use github issues to track bugs, feature requests, and to try and answer questions. You may file one here.

We use maven for most aspects of the build. Some important parts of the build execute in the "verify" phase of maven. We recommend when building at least running to the "verify" phase.
mvn verifyTests are described here.
The RAPIDS Accelerator For Apache Spark does provide some APIs for doing zero copy data transfer into other GPU enabled applications. It is described here.
Currently, we are working with XGBoost to try to provide this integration out of the box.
You may need to disable RMM caching when exporting data to an ML library as that library will likely want to use all of the GPU's memory and if it is not aware of RMM it will not have access to any of the memory that RMM is holding.
