PURPOSE: To execute the high-speed collection in the data collection and processing system for the parallel computer to collect the storage data for processor elements comprising the parallel computer.

CONSTITUTION: A control processor 3 sets one token flag for one processor element 1 for data collection. Further, a token flag shift instruction prepared as an adjacent communication construction for all processor elements and directing the shift of the token flag to the adjacent processor element located at the prescribed direction is repeatedly issued. A data output instruction prepared as the adjacent communications instruction for all processor elements and directing the output of data if there is a token flag and directing no output in the case there is no token flag is to be issued according to the token flag shift instruction.
