Re: "Give it time and I'm sure there will be some advanced boffinery on ARM."
"Given that bomb codes tend to coded in FORTRAN I'd guess in principle porting them to ARM would not be impossible."
Far from it; the gcc suite is available on ARM. I think porting between different versions/standards of FORTRAN would be a bigger issue.
In any case, you wouldn't be running the heavy lifting on ARM; all the heavy stuff would be run on the arrays of GPU-type accelerators that the ARMs manage.
