Listening to Material World on the BBC I was interested to learn that Intel now have a patent for a chip that also has a cosmic ray detector attached to allow the new superchips that are sensitive to cosmic rays to be told to do calculations again.
Apparently is more elegant that building huge amounts of shielding. Super computers have some many chips a cosmic ray can cause a computational error a few times a week !
I like the fact that the engineer thought around the problem rather than just working on more shielding.
