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.

840754dd42 Hand unrolled version of dslash in a separate class.
Useful to compare; raises Intel compiler from 9GFlop/s to 17.5 Gflops.
                   on ivybridge core. Raises Clang form 14.5 to 17.5

4dba8522a1 Got unpreconditioned conjugate gradient to run and converge on a random (uniform random,
not even SU(3) for now) gauge field. Convergence history is correctly indepdendent of decomposition
on 1,2,4,8,16 mpi tasks.
Found a couple of simd bugs which required fixed and enhanced the Grid_simd.cc test suite.
Implemented the Mdag, M, MdagM, Meooe Mooee schur type stuff in the wilson dop.

b4cd37276b Corrected some compilation errors (zolotarev.h) and SSE4 vsplat and conj to make cshift test pass. 2015-05-18 16:48:14 +09:00

11cb3e9a01 Getting closer to having a wilson solver... introducing a first and untested
cut at Conjugate gradient. Also copied in Remez, Zolotarev, Chebyshev from
Mike Clark, Tony Kennedy and my BFM package respectively since we know we will
need these. I wanted the structure of

algorithms/approx
algorithms/iterative

etc.. to start taking shape.

48f425d31c I have made the Cshift work successfully with open mp threading in
every routine. Collapse(2) is now working under clang-omp++.

6103c29ee3 Threading support rework.
Placed parallel pragmas as macros; implemented deterministic thread reduction in style of
BFM.

02ae26d091 Small tweak to enable benchmarking to suppress gauge field bandwidth as a test.
This is a short term hack while I benchmark.

a98c01c86a Integrated Lebesgue code and been playing with alternate implementations of the wilson dop without
any particular success in increasing the performance.

c72db6c6f6 Fixed the stencil sector and Wilson now agrees between stencil based implementation
and the cshift based implementation. Managed to reduce the volume of code in this
sector a little, but consolidation would be good, perhaps taking common
logic out into simple helper functions

25d523c0f4 Shaken out stencil to the point where I think wilson dslash is correct.
Need to audit code carefully, consolidate between stencil and cshift,
and then benchmark and optimise.
