Data processing control system, controller, data processing control method, program, and medium

A data processing control system comprising a controller for receiving an instruction directing a data processing operation, and for causing said received instruction to be executed across a plurality of data processing devices, wherein

• said controller (1) detects a difference in execution end timing of said instruction between designated two of said plurality of data processing devices across which said instruction is executed, (2) sends every received instruction to said plurality of data processing devices until the number of instructions being executed or waiting to be executed by said plurality of data processing devices reaches a predetermined number, (3) does not send any received instructions to said plurality of data processing devices but holds said received instructions in a queue once the number of instructions being executed or waiting to be executed by said plurality of data processing devices has reached said predetermined number, and (4) when the number of instructions being executed or waiting to be executed by said plurality of data processing devices has become zero by completing the execution thereof, starts sending said queued instructions in sequence to said plurality of data processing devices, and continues to send said queued instructions or every newly received instruction to said plurality of data processing devices until the number of instructions being executed or waiting to be executed by said plurality of data processing devices reaches said predetermined number, and wherein
• said predetermined number is varied according to said detected difference.

A data processing control method for receiving an instruction directing a data processing operation, and for causing said received instruction to be executed across a plurality of data processing devices, comprising the steps of:

• sending every received instruction to said plurality of data processing devices until the number of instructions being executed or waiting to be executed by said plurality of data processing devices reaches a predetermined number;
• not sending any received instructions to said plurality of data processing devices but holding said received instructions in a queue once the number of instructions being executed or waiting to be executed by said plurality of data processing devices has reached said predetermined number;
• and
• starting sending said queued instructions in sequence to said plurality of data processing devices when the number of instructions being executed or waiting to be executed by said plurality of data processing devices has become zero by completing the execution thereof, and continuing to send said queued instructions or every newly received instruction to said plurality of data processing devices until the number of instructions being executed or waiting to be executed by said plurality of data processing devices reaches said predetermined number.

A data processing control method for receiving an instruction directing a data processing operations and for causing said received instruction to be executed across a plurality of data processing devices, comprising the steps of:

• detecting a difference in execution end timing of said instruction between designated two of said plurality of data processing devices across which said instruction is executed;
• sending every received instruction to said plurality of data processing devices until said detected difference exceeds a prescribed limit;
• not sending any received instructions to said plurality of data processing devices but holding said received instructions in a queue once said difference has exceeded said prescribed limit;
• starting sending said queued instructions in sequence to said plurality of data processing devices when the number of instructions being executed or waiting to be executed by said plurality of data processing devices has become zero by completing the execution thereof;
• and
• detecting said difference again and continuing to send said queued instructions or every newly received instruction to said plurality of data processing devices until said detected difference exceeds said prescribed limit.
