Abstract
Embodiments of apparatuses, methods for partitioning systems, and partitionable and partitioned systems are disclosed. In one embodiment, a system includes processors and a partition manager. The partition manager is to allocate a subset of the processors to a first partition and another subset of the processors to a second partition. The first partition is to execute first operating system level software and the second partition is to execute second operating system level software. The first operating system level software is to manage the processors in the first partition as resources individually accessible to the first operating system level software, and the second operating system level software is to manage the processors in the second partition as resources individually accessible to the second operating system level software. The partition manager is also to present the second partition, including the second operating system level software, to the first operating system level software as platform level functionality embedded in the system.
