PROBLEM TO BE SOLVED: To prevent a malfunction when a program is restarted in one processor after transferring a command between processors in a multiprocessor system.SOLUTION: First control means 100 converts a function 27 called by a process 1 running on a first OS 20 into a command 29 to be interpreted in common by the first OS 20 and a second OS 23, and writes the converted command 29 to a command buffer 51 of second control means 200. The first control means 100 reads a status 30 indicating a result of the second control means 200 executing a system call of the second OS 23 corresponding to the written command 29, from the command buffer 51, converts the status 30 to a return value 28 to be interpreted by the process 1, and transmits it to the process 1. The first control means 100 discards the read status 30 when the process 1 is restarted after the command 29 is written to the command buffer 51. |
