Abstract: A distributed computing manager provides access to computing resources of a plurality of separate computing systems. The distributed computing manager emulates the distributed computing resources as a unitary computing system comprising an emulated processor, I/O, memory, and so on. The distributed computing manager distributes instructions, I/O requests, memory accesses, and the like, to respective computing systems, which emulate execution on any suitable computing platform. The distributed computing manager may be hardware agnostic and, as such, may not rely on proprietary virtualization infrastructure.
