3a3f54932a Implemented all SSE4 functions. 
A test code Grid_simd_new.cc has been created to test the new class.
Tests are all OK.

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.

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.

BFM.

cd90f55536 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.

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

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.

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.

a5b0c492d7 Rework of RNG to use C++11 random. Should work correctly maintaining parallel RNG across 
a machine. If a "fixedSeed" is used, randoms should be reproducible across different machine
decomposition since the generators are physically indexed and assigned in lexico ordering.
