PROBLEM TO BE SOLVED: To dynamically select program execution environments to be run in parallel according to execution states of programs in an information processor running a plurality of program execution environments in parallel by a single CPU. SOLUTION: Disclosed is a control method of an information processor equipped with: an operation number storage device which stores the number of operations of program execution environments; a program execution device which reads the number of operations out of the operation number storage device at the time of actuation and enabling one or two or more program execution environments corresponding to the number of operations to be run in parallel by one CPU; a device which stops the program execution device and interrupts program execution environments; and a device which actuates the program execution device and restarts the program execution environments. The number of operations in the operation number storage device is changed, the program execution device is stopped, and the 1st program execution environment is interrupted. Then the program execution device is automatically actuated to restart the 1st program execution environment, and a program execution environment corresponding to the number of operations changed by the operation number storage device can be run in parallel.
