PROBLEM TO BE SOLVED: To prevent the restart of a processing from being delayed without lowering a parallel processing speed with respect to the process taking-over method for the parallel processing system which adds an anti-fault function to a parallel processor. SOLUTION: This process taking-over method has a parallel processor 1 which performs plural processing in parallel, a processor 2 which takes over operation and performs a processing if the parallel processor 1 gets out of order, and a data storage means 3 which is accessed by the parallel processor 1 and processor 2 and stores data, and the parallel processor 1 after altering 1st data alters 2nd data relating to the 1st data. In this case, the parallel processor 1 has double data allowing a temporarily contradictious state, alters one data without exclusive control and reads out the other data, and performs exclusive control over the other data and transfers the other data to the processor 2, which takes over and performs the processing by using the transferred data as an initial value if the parallel processor 1 gets out of order. |
