Program compiler, program installer, and program install method

摘要

A program installation apparatus may install a program in an immediately executable form using a snapshot image. The snapshot image may store a partially executed result of the program. A snapshot point at which the snapshot image is created may be decided by analyzing dependency on a system execution environment of the program. The program installation apparatus may, in advance, execute a part of the program having no dependency on the system execution environment to create a snapshot image and then execute the remaining part of the program based on the snapshot image, reducing a start-up time of the program.
