### Bug report
_To help us tracking and solving more efficiently issues with Grid, please report problems using the issue system of GitHub rather than sending emails to Grid developers._
When you file an issue, please go though the following checklist:
1. Check that the code is pointing to the `HEAD` of `develop` or any commit in `master` which is tagged with a version number.
2. Give a description of the target platform (CPU, network, compiler).
3. Give the exact `configure` command used.
4. Attach `config.log`.
5. Attach `config.summary`.
6. Attach the output of `make V=1`.
7. Describe the issue and any previous attempt to solve it. If relevant, show how to reproduce the issue using a minimal working example.

The layout transformations are parametrised by the SIMD vector length. This adapts according to the architecture.

### Installation
### Quick start
First, start by cloning the repository:

../configure --enable-precision=double --enable-simd=AVX --enable-comms=mpi-auto --prefix=<path>
```
where `--enable-precision=` set the default precision (`single` or `double`),
`--enable-simd=` set the SIMD type (see possible values below), `--enable-
comms=` set the protocol used for communications (`none`, `mpi`, `mpi-auto` or
`shmem`), and `<path>` should be replaced by the prefix path where you want to
install Grid. The `mpi-auto` communication option set `configure` to determine
automatically how to link to MPI. Other options are available, use `configure
where `--enable-precision=` set the default precision,
`--enable-simd=` set the SIMD type, `--enable-
comms=`, and `<path>` should be replaced by the prefix path where you want to
install Grid. Other options are detailed in the next section, you can also use `configure
--help` to display them. Like with any other program using GNU autotool, the
`CXX`, `CXXFLAGS`, `LDFLAGS`, ... environment variables can be modified to
customise the build.

### Build configuration options
- `--prefix=<path>`: installation prefix for Grid.
- `--with-gmp=<path>`: look for GMP in the UNIX prefix `<path>`
- `--with-mpfr=<path>`: look for MPFR in the UNIX prefix `<path>`
- `--with-fftw=<path>`: look for FFTW in the UNIX prefix `<path>`
- `--enable-lapack[=<path>]`: enable LAPACK support in Lanczos eigensolver. A UNIX prefix containing the library can be specified (optional).
- `--enable-mkl[=<path>]`: use Intel MKL for FFT (and LAPACK if enabled) routines. A UNIX prefix containing the library can be specified (optional).
- `--enable-numa`: ???
- `--enable-simd=<code>`: setup Grid for the SIMD target `<code>` (default: `GEN`). A list of possible SIMD targets is detailed in a section below.
- `--enable-precision={single|double}`: set the default precision (default: `double`).
- `--enable-precision=<comm>`: Use `<comm>` for message passing (default: `none`). A list of possible SIMD targets is detailed in a section below.
- `--enable-rng={ranlux48|mt19937}`: choose the RNG (default: `ranlux48 `).
- `--disable-timers`: disable system dependent high-resolution timers.
- `--enable-chroma`: enable Chroma regression tests.
### Possible communication interfaces
The following options can be use with the `--enable-simd=` option to target different communication interfaces:
| `<comm>` | Description |
| ------------- | -------------------------------------------- |
| `none` | no communications |
| `mpi[-auto]` | MPI communications |
| `mpi3[-auto]` | MPI communications using MPI 3 shared memory |
| `shmem ` | Cray SHMEM communications |
For `mpi` and `mpi3` 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).
### Possible SIMD types
The following options can be use with the `--enable-simd=` option to target different SIMD instruction sets:
| String | Description |
| `<code>` | Description |
| ----------- | -------------------------------------- |
| `GEN` | generic portable vector code |
| `SSE4` | SSE 4.2 (128 bit) |
| `AVX` | AVX (256 bit) |
| `AVXFMA4` | AVX (256 bit) + FMA |
| `AVXFMA` | AVX (256 bit) + FMA |
| `AVXFMA4` | AVX (256 bit) + FMA4 |
| `AVX2` | AVX 2 (256 bit) |
| `AVX512` | AVX 512 bit |
| `AVX512MIC` | AVX 512 bit for Intel MIC architecture |
| `ICMI` | Intel ICMI instructions (512 bit) |
| `QPX` | QPX (256 bit) |
Alternatively, some CPU codenames can be directly used:
| String | Description |
| `<code>` | Description |
| ----------- | -------------------------------------- |
| `KNC` | [Intel Knights Corner](http://ark.intel.com/products/codename/57721/Knights-Corner) |
| `KNL` | [Intel Knights Landing](http://ark.intel.com/products/codename/48999/Knights-Landing) |
| `KNC` | [Intel Xeon Phi codename Knights Corner](http://ark.intel.com/products/codename/57721/Knights-Corner) |
| `KNL` | [Intel Xeon Phi codename Knights Landing](http://ark.intel.com/products/codename/48999/Knights-Landing) |
| `BGQ` | Blue Gene/Q |
#### Notes:
- We currently support AVX512 only for the Intel compiler. Support for GCC and clang will appear in future versions.
- For BG/Q only [bgclang](http://trac.alcf.anl.gov/projects/llvm-bgq) is supported. We do not presently plan to support more compilers for this platform.
- BG/Q performances are currently rather poor. This is being investigated for future versions.
### Build setup for Intel Knights Landing platform
The following configuration is recommended for the Intel Knights Landing platform:
``` bash
../configure --enable-precision=double\
--enable-simd=KNL \
--enable-comms=mpi3-auto \
--with-gmp=<path> \
--with-mpfr=<path> \
--enable-mkl \
CXX=icpc MPICXX=mpiicpc
```
where `<path>` is the UNIX prefix where GMP and MPFR are installed. If you are working on a Cray machine that does not use the `mpiicpc` wrapper, please use:
``` bash
../configure --enable-precision=double\
--enable-simd=KNL \
--enable-comms=mpi3 \
--with-gmp=<path> \
--with-mpfr=<path> \
--enable-mkl \
CXX=CC CC=cc
```
