First Investigations of the Vector Supercomputer SX-Aurora TSUBASA as a Co-Processor for Database Systems
BTW 2019 – Workshopband
The hardware landscape is currently changing from homogeneous multi-core systems towards heterogeneous systems with many different computing units, each with their own characteristics. This trend is a great opportunity for database systems to increase the overall performance if the heterogeneous resources can be utilized ...
Fighting the Duplicates in Hashing: Conflict Detection-aware Vectorization of Linear Probing
Hash tables are a core data structure in database systems, because they are fundamental for many database operators like hash-based join and aggregation. In recent years, the efficient vectorized implementation using SIMD (Single Instruction Multiple Data) instructions has attracted a lot of attention. Generally, all ...
