Control system for multi-processor apparatus

A control system for a multi-processor apparatus having a plurality of processors in which each of said plurality of processors are assigned to a process, said control system comprising:

• first determining means for determining whether or not a number of processors assigned to the process is insufficient;
• second determining means for determining whether or not a processor which is not busy is included in said plurality of processors;
• and
• adding means for, when said first determining means determines that the number of processors assigned to the process is insufficient and when said second determining means determines that a processor which is not busy is included in said plurality of processors, adding the processor which is not busy to processors assigned to the process,
• wherein said first determining means comprises:
• calculating means for calculating an average processing time for which each processor processes a predetermined amount of data in the process;
• and
• comparing means for comparing a waiting time and the average processing time to each other, the waiting time being a time for which data for the process waits to be processed by one of the processors assigned to the process, wherein when the waiting time is equal to or greater than the average processing time, said determining means determines that the number of processors assigned to the process is insufficient.

A control system for a multi-processor apparatus having a plurality of processors in which said plurality of processors are assigned to processes, said control system comprising:

• first determining means for determining whether or not a number of processors assigned to a first process is insufficient;
• second determining means for determining, based on a total time for which processors are assigned to a second process are in an idle state before the second process is completed, whether or not an excess processor for the second process is included in the processors assigned to the second process when said first determining means determines that the number of processors assigned to the first process is insufficient;
• releasing means for, when said second determining means determines that an excess processor for the second process is included in the processors assigned to the second process, releasing the excess processor from the second process;
• and
• adding means for adding the excess processor released from the second process by said releasing means to the processors assigned to the first process.
