Load-aware inter-co-processor parallelism in database query processing

作者：

Highlights：

• Contribute heuristics to enhance performance by exploiting inter-device parallelism

• Heuristics consider load and speed on (co-)processors.

• Extensive evaluation on four use cases: aggregation, selection, sort, and join

• Assess the performance of best heuristic for systems with multiple co-processors

• Discuss how operator-stream-based scheduling can be used in a query processor
