The Microbenchmarks Lab is derived from the spark-rapids-example repo. The microbenchmark on RAPIDS Accelerator For Apache Spark is to identify, test and analyze the best queries which can be accelerated on the GPU.
The queries are based on several tables in Parquet format derived from the TPC-DS benchmark, so that similar speedups can be reproducible by others. The microbenchmarks include commonly used Spark SQL operations such as expand, hash aggregate, windowing, and cross join and runs the same queries in CPU mode and GPU mode. You can see some queries are faster the second time, which can be caused by JVM JIT, initialization overhead or caching input data in the OS page cache, etc. The improved performance is influenced by many components, including the dataset’s scale factors and the GPU accelerator model.
