Chip multiprocessors (CMPs) present new opportunities for improving database performance on large queries. Because CMPs often share execution, cache, or bandwidth resources among many hardware threads, implementing parallel database operators that efficiently share these resources is key to maximizing performance. A crucial aspect of this parallelism is managing concurrent, shared input and output to the parallel operators. In this paper we propose and evaluate a parallel buffer that enables… CONTINUE READING
