a75b6f6e78 Large scale change to support 5d fermion formulations.
Have 5d replicated wilson with 4d gauge working and matrix regressing
to Ls copies of wilson.

5e72e4c0d9 Strip out the dslash kernel implementation 2015-05-26 19:55:18 +01:00

a32ac287bb 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

ffc00caea3 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.

cee363e28c Corrected some compilation errors (zolotarev.h) and SSE4 vsplat and conj to make cshift test pass. 2015-05-18 16:48:14 +09:00

d0e4673a3f 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.

541d52ab97 I have made the Cshift work successfully with open mp threading in
every routine. Collapse(2) is now working under clang-omp++.

c6baa3e657 Threading support rework.
Placed parallel pragmas as macros; implemented deterministic thread reduction in style of
BFM.

dc7132af71 Small tweak to enable benchmarking to suppress gauge field bandwidth as a test.
This is a short term hack while I benchmark.

c0ead94791 Integrated Lebesgue code and been playing with alternate implementations of the wilson dop without
any particular success in increasing the performance.

dcc23faa4a 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

b0485894b3 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.
