PARALLELISM IN XPRS
Michael R Stonebraker, Paul M. Aoki, Margo Seltzer · 2000
This paper discusses the approach being taken by XPRS, a software data base machine being built at Berkeley, toward intra-query parallelism. There are two components to our design. The first is a unique two-dimensional file system called FTD which automatically balances arm activity among multiple disks. The second component is the novel way that we construct parallel plans by making use of information about available main memory and the load average per processor. Both components are described in this paper.
