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 shapped 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 (eventually) both geometrically decompose into MPI tasks and across SIMD lanes.
|
||||
|
||||
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 SSE2 (128 bit) AVX, AVX2 (256 bit) and IMCI and AVX512 (512 bit) targets are supported.
|
||||
|
||||
These are presented as
|
||||
|
||||
vRealF, vRealD, vComplexF, vComplexD
|
||||
|
||||
internal vector data types. These may be useful in themselves for other programmers.
|
||||
The corresponding scalar types are named
|
||||
|
||||
RealF, RealD, ComplexF, ComplexD
|
||||
|
||||
MPI parallelism is UNIMPLEMENTED and for now only OpenMP and SIMD parallelism is present in the library.
|
||||
|
||||
You can give `configure' initial values for configuration parameters
|
||||
by setting variables in the command line or in the environment. Here
|
||||
is are examples:
|
||||
|
||||
./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -msse4" --enable-simd=SSE4
|
||||
|
||||
./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -mavx" --enable-simd=AVX1
|
||||
|
||||
./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -mavx2" --enable-simd=AVX2

### 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). Please give the full CPU part description, using for example `cat /proc/cpuinfo | grep 'model name' | uniq` (Linux) or `sysctl machdep.cpu.brand_string` (macOS) and the full output the `--version` option of your 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.

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-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-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).
|
||||
|
||||
### 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) |
|
||||
|
||||

#### 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.
|
||||
|
||||
### 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
|
||||
```
