In the supercomputer racket, you can be a niche player, a volume server maker with some HPC smarts, or a carcass that one of the other two feasts on. As a boutique supplier of high performance parallel clusters, Appro International has to use every weapon it can get its hands on to distinguish itself from IBM, Cray, and Silicon …
"Error correction inadequate"
Fixing up bit flips may seem important, but is hardly sufficient for a "serious HPC center" to trust the alleged answers generated. As is well-known, there are many other sources of error: floating-point rounding, measurement error, approximate physical constants, use of discrete models in place of continuous models. I wouldn't trust any answer, regardless of the presence of logic detecting bit-flips, unless the solutions are accompanied by guaranteed bounds on the errors. Now if these new GPUs had hardware implementations of Interval Arithmetic instructions, that might be something to get excited about.
