Efficient Query Processing on Many-core Architectures: A Case Study with Intel Xeon Phi Processor
Summary: PhiDB is an OLAP processor on Xeon Phi many-core with SMT, applying Phi-aware SIMD/prefetching and co-scheduled operators. Results show 14-33% gains from architecture-aware optimizations and 30% from concurrent scheduling, underscoring the need for operator- and scheduler-level redesign for future many-core DBs.
