paboyle 4908b77d46 Fixed conflicts. PLEASE avoid making wholesale cosmetic only changes, this created 
a HUGE amount of difficult to resolve and understand conflicts .

Wholesale formatting, reordering functions etc... in a central file like Tensor_class
or Grid_vector_types while others are also editing without making substantial functionality
changes creates pain.

paboyle 9db2c6525d updating benchmarks for red black 4d for Ls vectorised code 2016-07-14 23:44:02 +01:00
paboyle adbc7c1188 Adding files for multiple implementations (cache opt) and Ls vectorisation 
of the 5D cayley form chiral fermions for the 5d matrix. With Ls entirely
in the vector direction, s-hopping terms involve rotations.

The serial dependence of the LDU inversion for Mobius and 4d even odd
checkerboarding is removed by simply applying Ls^2 operations (vectorised
many ways) as a dense matrix operation.

This should give similar throughput but high flops (non-compulsory flops)
but enable use of the KNL cache friendly kernels throughout the code.

Ls is still constrained to be a multiple of Nsimd, which is as much as 8 for AVX512
with single precision.

paboyle 55f65b81b5 Improvements to the assembler interface that let us move chunks of the

guarantee L2 prefetching strategy is right since OMP can't distribute the
sub-chunks of work.
