### Description
This library provides data parallel C++ container classes with internal memory layout
that is transformed to map efficiently to SIMD architectures. CSHIFT facilities
are provided, similar to HPF and cmfortran, and user control is given over the mapping of
array indices to both MPI tasks and SIMD processing elements.
* Identically shaped arrays then be processed with perfect data parallelisation.
* Such identically shaped arrays are called conformable arrays.
The transformation is based on the observation that Cartesian array processing involves
identical processing to be performed on different regions of the Cartesian array.
The library will both geometrically decompose into MPI tasks and across SIMD lanes.
Local vector loops are parallelised with OpenMP pragmas.
Data parallel array operations can then be specified with a SINGLE data parallel paradigm, but
optimally use MPI, OpenMP and SIMD parallelism under the hood. This is a significant simplification
for most programmers.
The layout transformations are parametrised by the SIMD vector length. This adapts according to the architecture.
Presently SSE4, ARM NEON (128 bits) AVX, AVX2, QPX (256 bits), IMCI and AVX512 (512 bits) targets are supported.
These are presented as `vRealF`, `vRealD`, `vComplexF`, and `vComplexD` internal vector data types.
The corresponding scalar types are named `RealF`, `RealD`, `ComplexF` and `ComplexD`.
MPI, OpenMP, and SIMD parallelism are present in the library.

Bootstrapping grid downloads and uses for internal dense matrix (non-QCD operations) the Eigen library.

For the MPI interfaces the optional `-auto` suffix instructs the `configure` scripts to determine all the necessary compilation and linking flags. This is done by extracting the informations from the MPI wrapper specified in the environment variable `MPICXX` (if not specified `configure` will scan though a list of default names). The `-auto` suffix is not supported by the Cray environment wrapper scripts. Use the standard versions instead.

Knight's Landing with Intel Omnipath adapters with two adapters per node
presently performs better with use of more than one rank per node, using shared memory
for interior communication. This is the mpi3 communications implementation.
We recommend four ranks per node for best performance, but optimum is local volume dependent.

Since Dual socket nodes are commonplace, we recommend MPI-3 as the default with the use of
one rank per socket. If using the Intel MPI library, threads should be pinned to NUMA domains using
```
export I_MPI_PIN=1
```
This is the default.

#### Expected Skylake Gold 6148 dual socket (single prec, single node 20+20 cores) performance using NUMA MPI mapping):
mpirun -n 2 benchmarks/Benchmark_dwf --grid 16.16.16.16 --mpi 2.1.1.1 --cacheblocking 2.2.2.2 --dslash-asm --shm 1024 --threads 18
TBA
### Build setup for AMD EPYC / RYZEN
The AMD EPYC is a multichip module comprising 32 cores spread over four distinct chips each with 8 cores.
So, even with a single socket node there is a quad-chip module. Dual socket nodes with 64 cores total
are common. Each chip within the module exposes a separate NUMA domain.
There are four NUMA domains per socket and we recommend one MPI rank per NUMA domain.
MPI-3 is recommended with the use of four ranks per socket,
and 8 threads per rank.
The following configuration is recommended for the AMD EPYC platform.
``` bash
../configure --enable-precision=double\
--enable-simd=AVX2 \
--enable-comms=mpi3 \
CXX=mpicxx
```
If gmp and mpfr are NOT in standard places (/usr/) these flags may be needed:
``` bash
--with-gmp=<path> \
--with-mpfr=<path> \
```
where `<path>` is the UNIX prefix where GMP and MPFR are installed.
Using MPICH and g++ v4.9.2, best performance can be obtained using explicit GOMP_CPU_AFFINITY flags for each MPI rank.
This can be done by invoking MPI on a wrapper script omp_bind.sh to handle this.
It is recommended to run 8 MPI ranks on a single dual socket AMD EPYC, with 8 threads per rank using MPI3 and
shared memory to communicate within this node:
mpirun -np 8 ./omp_bind.sh ./Benchmark_dwf --mpi 2.2.2.1 --dslash-unroll --threads 8 --grid 16.16.16.16 --cacheblocking 4.4.4.4
Where omp_bind.sh does the following:
```
#!/bin/bash
numanode=` expr $PMI_RANK % 8 `
basecore=`expr $numanode \* 16`
core0=`expr $basecore + 0 `
core1=`expr $basecore + 2 `
core2=`expr $basecore + 4 `
core3=`expr $basecore + 6 `
core4=`expr $basecore + 8 `
core5=`expr $basecore + 10 `
core6=`expr $basecore + 12 `
core7=`expr $basecore + 14 `
export GOMP_CPU_AFFINITY="$core0 $core1 $core2 $core3 $core4 $core5 $core6 $core7"
echo GOMP_CUP_AFFINITY $GOMP_CPU_AFFINITY
$@
```
Performance:
#### Expected AMD EPYC 7601 dual socket (single prec, single node 32+32 cores) performance using NUMA MPI mapping):
mpirun -np 8 ./omp_bind.sh ./Benchmark_dwf --threads 8 --mpi 2.2.2.1 --dslash-unroll --grid 16.16.16.16 --cacheblocking 4.4.4.4
TBA
### Build setup for BlueGene/Q
To be written...
### Build setup for ARM Neon
To be written...
### Build setup for laptops, other compilers, non-cluster builds
Many versions of g++ and clang++ work with Grid, and involve merely replacing CXX (and MPICXX),
and omit the enable-mkl flag.
Single node builds are enabled with
```
--enable-comms=none
```
FFTW support that is not in the default search path may then enabled with
```
--with-fftw=<installpath>
```
BLAS will not be compiled in by default, and Lanczos will default to Eigen diagonalisation.
