Title:
SWITCHING CONTROL SYSTEM FOR PARALLEL PROCESSOR
Document Type and Number:
Japanese Patent JP3300776
Kind Code:
B2
Abstract:
PURPOSE: To enable efficient processor group switching by monitoring a proces sor fault and setting an optimum faulty processor ratio value corresponding to transaction contents and a transaction volume.
CONSTITUTION: If the parallel processor consisting of a current processor group 10 and a spare processor group 20 becomes faulty, current processors are switched to spare processors in group units. Each processor group is provided with monitor processors 11 and 21, the parallel processor is provided with a processor control part 30 for group switching, and the processor control part 30 is provided with a timer 303. Further, a scheduling table 302 of faulty processor ratio values by time indicating the rates of faulty processors in the current processor group 10 by time is set. The processor control part 30 when receiving a fault report from a current monitor processor determines the rate of faulty processors in the current processor group and performs switching from the current group to the spare group when the rate reaches the faulty processor ratio value set previously at the time when the rate is determined.
