TU Berlin & DFKI Database Systems Researchers Receive SIGMOD 2020 Best Paper Award

Database systems researchers at TU Berlin and DFKI were highly successful this year. Four of their papers were accepted at the 2020 ACM SIGMOD/PODS International Conference on the Management of Data. And, in particular, one of the paper’s received the 2020 ACM SIGMOD Best Paper Award.
The paper entitled “Pump Up the Volume: Processing Large Data on GPUs with Fast Interconnects,” by Clemens Lutz, Sebastian Breß, Steffen Zeuch, Tilmann Rabl (now at HPI), and Volker Markl explores the use of GPUs to accelerate database query processing. GPUs are generally ill-suited for large-scale data processing for two reasons: (1) the on-board memory capacity is too small to store large datasets, and (2) the interconnect bandwidth to CPU main-memory is insufficient for ad-hoc data transfers. As a result, GPU-based systems face data transfer bottlenecks and do not scale to large datasets. In the paper, the authors demonstrate how a fast interconnect, such as NVLink 2.0 (linking dedicated GPUs to a CPU) can overcome the two scalability issues for a no-partitioning hash join. Consequently, the experiments achieved a speed-up of up to 18x over PCI-e 3.0 and up to 7.3x over an optimized CPU implementation.
