28022755ae Stencil class name global change to StencilImpl typedef 2015-11-06 05:30:17 -06:00

55cfc89459 * Finished the template/policy style introduction of gparity, except the gparity force terms.
So valence sector looks ok.

FermionOperatorImpl.h provides the policy classes.

Expect HMC will introduce a smearing policy and a fermion representation change policy template
param. Will also probably need multi-precision work.

* HMC is running even-odd and non-checkerboarded (checked 4^4 wilson fermion/wilson gauge).

There appears to be a bug in the multi-level integrator -- <e-dH> passes with single level but
not with multi-level.

In any case there looks to be quite a bit to clean up.

This is the "const det" style implementation that is not appropriate  yet for clover since
it assumes that Mee is indept of the gauge fields. Easily fixed in future.

84a66476ab Rework/global edit to enforce type templating of fermion operators.
Allows multi-precision work and paves the way for alternate BC's and such like
allowing for example G-parity which is important for K pipi programme.
In particular, can drive an extra flavour index into the fermion fields
using template types.

4fe110bd07 Two flavour HMC for Wilson/Wilson is conserving energy.
Still to check plaq and <e(-dH)>, but nevertheless this is
progress

d9d4c5916a Elemental force term for Wilson dslash added and tests thereof passing.
Now need to construct pseudofermion two flavour, ratio, one flavour, ratio
action fragments.

d6f1ddf99c Conjugate residual algorithm; some more unary functions 2015-06-08 12:04:59 +01:00

3845f267cb Domain wall fermions now invert ; have the basis set up for
Tanh/Zolo * (Cayley/PartFrac/ContFrac) * (Mobius/Shamir/Wilson)
Approx        Representation               Kernel.

All are done with space-time taking part in checkerboarding, Ls uncheckerboarded

Have only so far tested the Domain Wall limit of mobius, and at that only checked
that it
i)  Inverts
ii) 5dim DW == Ls copies of 4dim D2
iii) MeeInv Mee == 1
iv) Meo+Mee+Moe+Moo == M unprec.
v) MpcDagMpc is hermitan
vi) Mdag is the adjoint of M between stochastic vectors.

That said, the RB schur solve, RB MpcDagMpc solve, Unprec solve
all converge and the true residual becomes small; so pretty good tests.

5644ab1e19 Large scale change to support 5d fermion formulations.
Have 5d replicated wilson with 4d gauge working and matrix regressing
to Ls copies of wilson.
