e8b95bd35b Clean up finished. Could shrink Lanczos to around 400 lines at a push 2017-06-21 02:50:09 +01:00
7e35286860 Simplified lanczos, added Eigen diagonalisation.
Curious if we can deprecate dependencly on BLAS.
Will see when we get 48^3 running on our BG/Q port

0486ff8e79 Improved the lancos 2017-06-20 18:46:01 +01:00
e9cc21900f Block solver complete for staggered. Now stable on mass 0.003 and
gives 8x (!) speed up on Haswell laptop vs. standard CG for 8 RHS solves.

166 iterations vs. 537 iterations so algorithmic gain + 2x in flop rate gain.

Better than a slap in the face with a wet kipper.

8e161152e4 MultiRHS solver improvements with slice operations moved into lattice and sped up.
Block solver requires a lot of performance work.
