Peter Boyle 802e94e9ca First pass at continued fraction; solver and even odd decomposition tests pass. 
Have to make ContFrac class virtual and derive end non-abstract actions for the particular
cases.

Peter Boyle 68e26140ee Mobius Caley form, Mobius Zolotarev operators. Pass Even Odd vs unprec test and hermiticity checks 
in tests/Grid_any_evenodd.cc; will work on inversion tests shortly.

Peter Boyle 494d2b8b61 Reorg; moving prec/unprec/schur CG for Wilson and DWF into tests as these are really tests and not benchmarks 
(no performance reports, only convergence test).

Peter Boyle 66d997e031 Large scale change to support 5d fermion formulations. 
Have 5d replicated wilson with 4d gauge working and matrix regressing
to Ls copies of wilson.

Peter Boyle a6e1ea216d 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.

Peter Boyle 1887c77498 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.

ET's are still incomplete.

Peter Boyle e647cf0459 Default to single node. Move to command line args. 2015-05-10 15:27:38 +01:00
Peter Boyle 8919bf9e0a Single node default. Should expose this as command line args, but haven't sorted out 
Grid_initialize to handle this. Should put this on the TODO list.

Peter Boyle c0ead94791 Integrated Lebesgue code and been playing with alternate implementations of the wilson dop without 
any particular success in increasing the performance.
 2015-04-30 16:39:06 +01:00
Peter Boyle d8ffa09e3b Benchmark wilson dhop now; 14.6GF on one core, not as fast as SU(3)xSU(3) [23GF] but still not too shabby. 
Disassembling output shows ugly sequences in the permute sector. Could comparatively benchmark with and without
the if-else structure to see how much I'm losing.

Drops to 9GF as it falls out of cache. Moving to Lebesgue ordering should help there. Substantive progress.
 2015-04-29 06:50:18 +01:00
Peter Boyle 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
 2015-04-29 06:23:56 +01:00
Peter Boyle 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.
