From: owner-nanog () merit edu [mailto:owner-nanog () merit edu] On Behalf Of Warren Kumari Yup, Sandia National Labs made a radiation hardened Pentium and, as far as I remember, was working on a hardened SPARC -- there was also some work done (AFAIR on PPC) whereby 3 processors would run the same instructions and vote on the output...Thinking of perhaps Resilience? http://www.resilience.com/ God, those things were horrid before they realized that the business model of assuming "The app will always be OK, the issue will be the hardware" was completely misguided. I forget what the product was named at the time, but I'll never forget what a piece of crap it was.
Eh, they're not the only folks to have had voting-muti-cpu-lockstep-execution hardware platforms. Stratus did it for years; the Tandem Integrity S2 (to which I ported Emacs 18.55 many moons ago) was similar. ---Rob
