The toolkit is moving towards supporting quad-precision (via the __float128 GNU quadmath library), and possibly to higher precision via the GMP library.

Moving to quad precision involves several issues

  • treatment of constants, eg pi, sqrt2, etc need float128 support
  • BLAS/LAPACK library, it looks like a good candidate is MPACK
  • EXPOKIT needs porting to __float128. Or maybe use a different library, see eg
  • ARPACK needs porting to __float128. Probably a big job, but maybe someone has already done it?
  • Handling adjustable parameters, for example eigensolver tolerances, and default values.
