Fault Diagnosis in a Boolean n Cube Array of Microprocessors
Armstrong, Gray · IEEE Transactions on Computers · 1981
Fault- tolerant characteristics of a Boolean n cube array of microprocessors are analyzed. Connectivity properties of the network graph are used to show that n processor or link failures are required to isolate a processor. For processor failures the network is shown to be n (one step) diagnosable. A testing algorithm is presented which can diagnose up to n processor failures.
