PROGRAM, INFORMATION PROCESSING SYSTEM, AND PROGRAM MIGRATION METHOD

摘要

Efficient execution of a program becomes possible after completion of a migration process, while execution of the program is started early on a migration destination computer. A first executing means (2) executes a first program (1a) by emulating information processing in a first operational environment in which the first program (1a) is executable. A generating means (3) generates, in parallel with the execution of the first program (1a), a second program (1b) which is executable in a second operational environment of an information processing system (CP) and which is capable of acquiring the same processing result as the first program (1a). A second executing means (4) terminates the execution of the first program (1a) by the first executing means (2) and also executing the second program (1b), after the generation of the second program (1b) is completed.
