摘要

NEC Corporation offers a vector engine as a specialized co-processor having two unique features. On the one hand, it operates on vector registers multiple times wider than those of recent mainstream x86-processors. On the other hand, this accelerator provides a memory bandwidth of up to 1.2TB/s for 48GB of main memory. Both features are interesting for analytical query processing: First, vectoriza...
