KeRRaS: Sort-Based Database Query Processing on Wide Tables Using FPGAs
DaMoN '23: Proceedings of the 19th International Workshop on Data Management on New HardwarePages 1–9https://doi.org/10.1145/3592980.3595300Sorting is an important operation in database query processing. Complex pipeline-breaking operators (e.g., aggregation and equi-join) become single-pass algorithms on sorted tables. Therefore, sort-based query processing is a popular method for FPGA-...

Accelerating User-Defined Aggregate Functions (UDAF) with Block-wide Execution and JIT Compilation on GPUs
DaMoN '23: Proceedings of the 19th International Workshop on Data Management on New HardwarePages 19–26https://doi.org/10.1145/3592980.3595307The GPU-accelerated DataFrame library cuDF has become increasingly popular for data analytics applications due to its superior performance against CPU-based DataFrame libraries such as Pandas. One of the frequently-used operations in dataframe ...
