Peter Boyle a21036e69a Reworking to keep intel compiler happy 2015-05-19 21:29:07 +01:00
Peter Boyle 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.

Peter Boyle 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.

Peter Boyle 0b4d3544b9 clang++ 3.4/5/7 compile happy for AVX and SSE 
icpc compiles happy on MacOSX both with -xCOMMON-AV512 and native AVX

gcc-5 does not compile happy; can work around by renaming lattice peek/poke/transpose/trace templates
relative to tensor ones, but gcc goes into a recursive template instantiation due to
matching error. I think this is a gcc bug and have filed a report https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66153

 2015-04-30 09:46:48 +01:00
Peter Boyle b7090ebba4 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 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
 2015-04-29 06:23:56 +01:00
Peter Boyle 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.
