 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.
+* Such identically shapped arrays are called conformable arrays.

-### Quick start
-First, start by cloning the repository:
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+are examples:

-``` bash
-git clone https://github.com/paboyle/Grid.git
-```
+     ./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -msse4" --enable-simd=SSE4

-Then enter the cloned directory and set up the build system:
+     ./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -mavx" --enable-simd=AVX

-``` bash
-cd Grid
-./bootstrap.sh
-```
+     ./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -mavx2" --enable-simd=AVX2

-Now you can execute the `configure` script to generate makefiles (here from a build directory):
+     ./configure CXX=icpc CXXFLAGS="-std=c++11 -O3 -mmic" --enable-simd=AVX512 --host=none
     
-``` bash
-mkdir build; cd build
-../configure --enable-precision=double --enable-simd=AVX --enable-comms=mpi-auto --prefix=<path>
-```
+Note: Before running configure it could be necessary to execute the script 
       
-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.
+       script/filelist

-Finally, you can build and install Grid:

-``` bash
-make; make install
-```
     
-To minimise the build time, only the tests at the root of the `tests` directory are built by default. If you want to build tests in the sub-directory `<subdir>` you can execute:
+For developers:
+Use reconfigure_script in the scripts/ directory to create the autotools environment 

-``` bash
-make -C tests/<subdir> tests
-```
-If you want to build all the tests at once just use `make tests`.
-
-### 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 NUMA first touch optimisation
- `--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-gen-simd-width=<size>`: select the size (in bytes) of the generic SIMD vector type (default: 32 bytes).
- `--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.
- `--enable-doxygen-doc`: enable the Doxygen documentation generation (build with `make doxygen-doc`)
-
-### Possible communication interfaces
-
-The following options can be use with the `--enable-comms=` option to target different communication interfaces:
-
-| `<comm>`       | Description                                                   |
-| -------------- | ------------------------------------------------------------- |
-| `none`         | no communications                                             |
-| `mpi[-auto]`   | MPI communications                                            |
-| `mpi3[-auto]`  | MPI communications using MPI 3 shared memory                  |
-| `mpi3l[-auto]` | MPI communications using MPI 3 shared memory and leader model |
-| `shmem `       | Cray SHMEM communications                                     |
-
-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.  
-
-### Possible SIMD types
-
-The following options can be use with the `--enable-simd=` option to target different SIMD instruction sets:
-
-| `<code>`    | Description                            |
-| ----------- | -------------------------------------- |
-| `GEN`       | generic portable vector code           |
-| `SSE4`      | SSE 4.2 (128 bit)                      |
-| `AVX`       | AVX (256 bit)                          |
-| `AVXFMA`    | AVX (256 bit) + FMA                    |
-| `AVXFMA4`   | AVX (256 bit) + FMA4                   |
-| `AVX2`      | AVX 2 (256 bit)                        |
-| `AVX512`    | AVX 512 bit                            |
-| `QPX`       | QPX (256 bit)                          |
-
-Alternatively, some CPU codenames can be directly used:
-
-| `<code>`    | Description                            |
-| ----------- | -------------------------------------- |
-| `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 of Grid when the AVX512 support within GCC and clang will be more advanced.
- 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.
- The vector size for the `GEN` target can be specified with the `configure` script option `--enable-gen-simd-width`.
-
-### 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=mpi-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=mpi       \
-             --with-gmp=<path>        \
-             --with-mpfr=<path>       \
-             --enable-mkl             \
-             CXX=CC CC=cc
-```

-# Copyright (C) 2004 Oren Ben-Kiki
-# This file is distributed under the same terms as the Automake macro files.
-
-# Generate automatic documentation using Doxygen. Goals and variables values
-# are controlled by the various DX_COND_??? conditionals set by autoconf.
-#
-# The provided goals are:
-# doxygen-doc: Generate all doxygen documentation.
-# doxygen-run: Run doxygen, which will generate some of the documentation
-#              (HTML, CHM, CHI, MAN, RTF, XML) but will not do the post
-#              processing required for the rest of it (PS, PDF, and some MAN).
-# doxygen-man: Rename some doxygen generated man pages.
-# doxygen-ps: Generate doxygen PostScript documentation.
-# doxygen-pdf: Generate doxygen PDF documentation.
-#
-# Note that by default these are not integrated into the automake goals. If
-# doxygen is used to generate man pages, you can achieve this integration by
-# setting man3_MANS to the list of man pages generated and then adding the
-# dependency:
-#
-#   $(man3_MANS): doxygen-doc
-#
-# This will cause make to run doxygen and generate all the documentation.
-#
-# The following variable is intended for use in Makefile.am:
-#
-# DX_CLEANFILES = everything to clean.
-#
-# This is usually added to MOSTLYCLEANFILES.
