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 87418e7df1 Slightly faster prefetching perf. 2016-06-13 02:32:52 -07:00
paboyle 55f65b81b5 Improvements to the assembler interface that let us move chunks of the 
site and s loop into the kernels. This will save on function call overhead and
guarantee L2 prefetching strategy is right since OMP can't distribute the
sub-chunks of work.

paboyle f7ca6ca889 Bernoulli reenabled -- using integral type for the discrete_distribution, but 
then casts in the fill
 2016-04-30 03:48:28 -07:00
paboyle ec4a9b7f6c The Bernoulli gives a no compile due to a static assertion that the type be integral 
in 4.7 random.h

Probably need to go through an Integer type, and then conver to real after the random draw
to make clean.
 2016-04-30 03:42:24 -07:00
paboyle 5341977948 IMCI fixes. Thought I had committed these. The "real" disambiguation 
between std::real and Grid::real shouldn't have been necessary and I don't
know why only the icpc v16.0 on babbage hits it.
May need a longer term rename of Grid::real or some careful EnableIf work.

paboyle 04072a5e1f Rotate is a temporary hack. Would like to merge ALL 
permutes as rotates of length 2, and make any rotate active
over any subset of lane bits. This is hard, and requires general
permute; current intrinsics mean this is only really possible for specific
case by case encodings as presently performed. Intel could produce a general
permute.. would help. IBM did it in VMX.
