to make a look sufficiently simple to thread.

Peter Boyle 1271508ca2 Bug fix for spread out in x (EO) direction. 
This is really annoying -- it is very hard to thread the loops with the index
recursion on buffer offset in the red-black case. Must think of a good threading
solution here.

Peter Boyle 5ef42add2d Changes to remove warnings under icc; disambiguate AVX512 from IMCI correctly 
and drop swizzles in AVX512. Don't know why these compiled.

Peter Boyle 2f38ebc446 Reintroducing the hand unrolled loops 2015-09-08 17:45:30 +01:00
Peter Boyle 638d6675ee Tested rms dH is ~ dt^4 numerically, so believe the ForceGradient is correct now. 
Paranoia makes me want to diddle with the FG step to ensure dt^2 reappears.
 2015-08-31 16:33:20 +01:00
Peter Boyle 357c6ab46d Reunitarise. Complete the HMC and integrator changes. 2015-08-31 16:32:04 +01:00
Peter Boyle 755dca9533 Added ForceGradient integrator. dH dropped so seems to work. Will only 
believe it is right once I have pulled a dt^4 error scaling plot out.
 2015-08-31 06:23:02 +01:00
Peter Boyle 29fd004d54 Unified integrator and integrator algorithm into virtual class used as a policy for the 
HMC.
 2015-08-30 13:39:19 +01:00
Peter Boyle eed889ea05 Update on todo list 2015-08-30 12:23:08 +01:00
Peter Boyle aa52fdadcc Global edit on HMC sector -- making GaugeField a template parameter and 
preparing to pass integrator, smearing, bc's as policy classes to hmc.

Propose to unify "integrator" and integrator algorithm in a base/derived
way to override step. Want to read through ForceGradient to ensure
that abstraction covers the force gradient case.
 2015-08-30 12:18:34 +01:00
Peter Boyle 76d752585b Started a tidy up in the HMC sector. Now comfortable with the two level integrators; 
to a little figure out what Guido had done & why -- but there is a neat saving of force
evaluations across the nesting time boundary making use of linearity of the leapP in dt.

I cleaned up the printing, reduced the volume of code, in the process sharing printing
between all integrators. Placed an assert that the total integration time for all integrators
must match at end of trajectory.

Have now verified e-dH = 1 for nested integrators in Wilson/Wilson runs with both
Omelyan and with Leapfrog so substantial confidence gained.
