In a simple view of the world, an application running on a multicore system should run at least as fast as the same application runs on a single-core system with the same CPU power. Unfortunately, in practice, that is not the case. However, by implementing application parallelism and using an SMP OS and an embedded hypervisor, one can solve the challenge and realize dramatic performance improvements.
Advances in software and hardware technologies now make it feasible to use both embedded and desktop operating systems in a secure military system. Robert examines enablers such as a secure separation kernel and an embedded software hypervisor, then explains uses of desktop OSs in secure military systems.

Virtualization is a key technology in today's commercial and military technology industries, but it has historically presented developers with difficulties in information assurance based systems. However, Intel's VT-x and VT-d hardware extensions are breathing new life into the virtualization process and show promise to become the de facto methods for implementing virtualization.
