Resum
Database management systems (DBMS) have become an essential tool for research and industry and are often a significant component of data centres. This work takes a top-down approach to accelerating decision support systems (DSS) on x86-64 microprocessors using vector ISA extensions. In the first step, a leading DSS DBMS is analysed for potential data-level parallelism. We discuss why the existing multimedia SIMD extensions (SSE/AVX) are not suitable for capturing this parallelism and propose a c...
