My understanding is that it's not compatible with modern processors, and new hardware would be required to efficiently execute it.
It seems to be a superset of floating point (and fixed point?) though, so maybe LAPACK could still work? I may be misreading or misunderstanding this however.
- methodOverdrive 11y agoNew hardware would be needed. I think libraries like LAPACK basically are fast because they do a good job taking advantage of the hardware implementation of floating point math, and are written with sufficient understanding of the format to mitigate approximation errors. Therefore you would probably need to rewrite huge parts of such libraries to use the new Unum hardware or software - though doing so might be relatively straightforward - as you say, Unum can be seen as a superset of floating point and it does support all of the same operations.
