A fault-tolerant computer system architecture includes two types of operating domains: a conventional first domain (DID) that processes data and instructions, and a novel second domain (MM domain) which includes mentor processors for mentoring the DID according to “meta information” which includes but is not limited to data, algorithms and protective rule sets. The term “mentoring” (as defined herein below) refers to, among other things, applying and using meta information to enforce rule sets and/or dynamically erecting abstractions and virtualizations by which resources in the DID are shuffled around for, inter alia, efficiency and fault correction. Meta Mentor processors create systems and sub-systems by means of fault tolerant mentor switches that route signals to and from hardware and software entities. The systems and sub-systems created are distinct sub-architectures and unique configurations that may be operated as separately or concurrently as defined by the executing processes.
