ABSTRACT:
To provide a multi-processing system capable of continuing an operation with efficiency even if a failure occurs in a processor during a system operation. A multi-processing system according to an embodiment of the invention includes: a memory storing a program and information necessary for executing the program; a processor manager reading the program from the memory, dividing the read program into threads with priority, and assigning the threads to at least two processors based on the priority of the threads and a processing state of each processor; the at least two processors executing the threads assigned by the processor manager; and a processing data manager storing information necessary for executing the thread assigned by the processor manager, and outputting the stored information necessary for executing the assigned thread to the memory if a failure occurs in one of the processors.
