Reliability issues

 Nearly 40 years ago in Alabama we had a lab with a dozen or so PCs in it. I don't think we ever had all of them working at once. My colleagues at ESU tell me that in the student University Physics lab they typically have maybe half of the computers working at any given time. My blog of 14 December 2015 shows the architecture for embodied A.s.a. H. AI experiments involving 3 PCs and 2 microcontrollers. This operated fairly reliably using commodity hardware. As we move to a larger number of processors, however, we have had issues with reliability. We may have to replace each single processor with 2 or 3 processors in order to provide a backup, as is done on spacecraft, for example.
