Angel Operating System
Definition - What does Angel Operating System mean?
The Angel operating system is an experimental multikernel OS for multiprocessor systems that is based on a single, coherent and uniform virtual address space. Its biggest feature is the unification of naming and interprocess communication in both distributed and shared memory multiprocessor systems by making use of distributed shared memory techniques when shared memory is not already offered by the hardware.
Angel was developed at Imperial College and City University in London.
Techopedia explains Angel Operating System
The Angel operating system was a project jointly undertaken by Imperial College and City University of London. The project was a follow-up to the earlier MESHIX operating system, which taught the developers some valuable lessons they would re-implement in Angel.
The principle behind this OS is using shared and distributed memory in multiprocessor systems where it is not implemented in hardware. The use of client-server cross-mapping optimizes the interprocess communication between the processor and its support hardware, so it becomes more efficient as the number of processors increases.
