PARALLEL DATA PROCESSING SYSTEM, COMPUTER, AND PARALLEL DATA PROCESSING METHOD

摘要

A parallel data processing system includes a parallel data processing execution unit for reading a data from a data set including a first data set that includes a plurality of first data and a second data set that includes a plurality of second data and executing processing. The parallel data processing execution unit (A) reads the first data from the first data set, and acquires a first value from the first data based on first format information acquired from an application, (B) generates one or more threads for respectively reading one or more second data corresponding to the first value from the second data set based on first reference information acquired from the application, (C) executes (A) and (B) on one or more first data in the first data set, and (D) executes a plurality of the threads in parallel.

1. A parallel data processing system of a single computer in a computer system in which a plurality of computers execute parallel data processing, the parallel data processing system comprising:
a parallel data processing execution unit being configured to read a data from a data set including a first data set that includes a plurality of first data and a second data set that includes a plurality of second data, and execute processing, the parallel data processing execution unit being configured to
(A) read the first data from the first data set, and acquire a first value from the first data based on first format information acquired from an application,(B) generate one or more threads for respectively reading one or more second data corresponding to the first value from the second data set based on first reference information acquired from the application,(C) execute (A) and (B) on one or more first data in the first data set, and(D) execute a plurality of the threads in parallel.
