Embodiment Construction

[0012] An operating system provides an interface between application programs (or simply, applications) and computer hardware to allow applications to interact with the hardware.

[0013] Develop applications for specific operating systems. However, operating systems are distributed with each release (such as Windows different service packs...) and, as a result, maintaining compatibility with applications is a huge challenge. For example, if an application was developed for version one of the operating system, and the computer is upgraded to version two, the application may no longer function or function in a correct manner. While OS vendors spend considerable resources maintaining compatibility, each OS release inevitably results in a large number of broken applications. This is especially troublesome for enterprises where rich and critical line-of-business (LOB) applications are disrupted by new operating system releases.

[0014] One way to solve the compatibility probl...

Abstract

Application compatibility is facilitated by use of library operating systems. Library operating systems can encapsulate portions of an application likely to break application compatibility. An application can be bound to a compatible library operating system that operates over a host operating system. Furthermore, library operating system version can be greater than, equal, or less than the version of the host operating system. Consequently, both backward and forward compatibility is enabled.

Description

Background technique [0001] The library approach to operating system (OS) constructs is supported by several operating systems designed in the 1990s. The concept of a library OS is that the entire personality of the OS on which an application depends runs as a library in its address space. An OS personality is the implementation of the OS's application programming interfaces (APIs) and application-visible semantics (the OS services used to build applications). Early proponents of the library OS approach initially argued that a library OS could allow better performance through customization to each application. For example, disk I / O bound applications with special file access patterns can achieve better performance by using a custom file-system storage stack rather than using the default sequential prefetch heuristics. [0002] Like many of its contemporaries, the library OS approach has been largely forgotten due to the growth of modern virtual machines. While most contempo...
