Octopus编译与安装
1. 简介
Ocotpus 是一款科学计算软件,可以对多种不同体系进行从头计算(ab initio)的模拟。在密度泛函理论(DFT)的理论框架下用量子力学来描述电子, 而核用经典的点粒子描述,电子-核相互作用以赝势近似来描述。Octopus可以进行基态计算,也可以利用时间密度泛函(TDDFT)进行时间依赖的模拟。
Octopus 还支持MPI和OpenMP来进行并行计算,也支持OpenCL和CUDA利用GPU计算
Octopus是一款Linux系统下的免费软件,在GNU通用公共许可证框架下发布,你可以免费下载,使用,修改。
Octopus的安装过程比较复杂,因为它有很多依赖库。笔者根据octopus官网提供的详细安装指南,在此分享如何在个人计算机 CentOS7.9 系统中安装Octopus的全过程。
2. 编译器相关
2.1 编译器
Octopus的代码使用标准 Fortran 2003写成,还有一些例程(routines)是使用C语言编写,所以我们需要一个C编译器和Fortran 2003 编译器。命令行下直接使用
yum
命令安装即可。
$ sudo yum install gcc #C 编译器
$ sudo yum install gfortran #fortran 编译器
注:最好使用gnu 8.3.0或更高版本
检查是否已经安装过gcc,可以输入以下命令:
gcc --version #意为查看gcc的版本
如果已经安装,则会输出相应版本号:
gcc (GCC) 8.3.0

2.2 编译器标志
通常编译器标志(Compiler flags)为系统自动选择的优化标志,但在安装Octopus过程中,需要我们指定标志,亲测使用不同标志会导致安装报错。这里,C编译器标志指定为 -O3(大写字母O),fortran编译器标志为 -O3 -ffree-line-length-none ,目前还不需要指定操作,在后面安装依赖库的时候才需要指定标志。
3. 依赖库
3.1 依赖库的安装
首先,
make
,automake
,m4
,libtool
这几个包是必要条件,可以直接用yum
安装,使用-–version
来检查是否安装成功。
sudo yum install make
sudo yum install automake
sudo yum install m4
sudo yum install libtool
其中make和automake是重要的编译工具,在linux环境下安装软件,一般都通过 配置->编译->安装 这个过程实现,即:
./configure -> make -> make install
m4
是是一个通用的宏处理器,大多数人需要m4
仅仅是因为GNU autoconf
中的configure
脚本依赖它。libtool
是处理动态链接库的工具,可以解决库依赖的问题,将使用动态库的复杂性隐藏在统一、可移植的接口中。
接下来还有5个数学库:
BLAS
,LAPACK
,GSL
,FFTW3
,LibXC
,下面逐一介绍。
在安装数学库之前,我们先创建一个文件夹来作为各种库的安装位置,一般放在
/opt/libraries
。
3.2 安装BLAS
BLAS (Basic Linear Algebra Subprograms)即基本线性代数子程序,提供用于执行基本矢量和矩阵运算的标准构建块的例程。1级BLAS执行标量,矢量和矢量-矢量运算,2级BLAS执行矩阵矢量运算,3级BLAS执行矩阵运算。 由于BLAS高效,便携且广泛可用,因此它们通常用于开发高质量线性代数软件,例如
LAPACK
。首先在网上下载压缩包:blas.tgz[http://www.netlib.org/blas/blas.tgz]
解压压缩包并进入新创建的 BLAS 文件夹
编辑
make.inc
文件,并修改fortran
编译器的标志为:(可以不做修改如果不报错的话)
FORTRAN = gfortran
OPTS = -O3 -ffree-line-length-none
DRVOPTS = $(OPTS)
NOOPT =
LOADER = gfortran
LOADOPTS =
接下来使用
make
命令来进行编译,这会花费一段时间。
make
然后在当前路径下创建新文件夹
lib
mkdir lib
将make命令后新产生的文件 blas_LINUX.a 复制到 ./lib/ 文件夹下并重命名
cp blas_LINUX.a ./lib/libblas.a
注:产生的新文件总是叫
blas_LINUX.a
,独立于你所用的操作系统,只是叫这个名字而已。
3.3 LAPACK
Lapack 即 Linear Algebra PACKage,是一个线性代数包,它提供了求解联立线性方程组,线性方程组最小二乘解,特征值问题和奇异值问题的例程,还提供了相关的矩阵因子分解(
LU
,Cholesky
,QR
,SVD
,Schur
,广义Schur
),以及相关计算。首先在网上下载压缩包:lapack.tgz[http://www.netlib.org/lapack/lapack.tgz]
解压压缩包并进入新产生的
lapack
文件夹复制
make.inc.example
文件为make.inc
cp make.inc.example make.inc
编辑
make.inc
文件,并修改相应编译器的标志为:(可以不做修改如果不报错的话)
FORTRAN = gfortran
OPTS = -O3 -ffree-line-length-none
DRVOPTS = $(OPTS)
NOOPT =
LOADER = gfortran
LOADOPTS =
接下来使用
make lib
命令来进行编译,这会花费一段时间。
make lib
将新产生的文件
liblapack.a
复制到./lib/
文件夹下并重命名
cp liblapack.a basedir/lib/liblapack.a
注:产生的新文件可能叫
lapack_LINUX.a
(官方教程产生的) ,也可能叫liblapack.a
(笔者电脑产生的)
3.4 GSL
这是一个GNU数学函数库,该库提供了广泛的数学例程,如随机数生成器,特殊函数和最小二乘拟合。
首先下载压缩包 gsl-2.6.tar.gz[ftp://ftp.gnu.org/gnu/gsl/gsl-2.6.tar.gz]
解压压缩包并进入新产生的文件夹
运行配置文件:
./configure CC="gcc" --prefix=/opt/libraries/gnu8-gsl/2.7 --disable-shared --enable-static
注:
configure
命令的参数解释之--prefix
: 该参数指定了安装路径,这里我们把库安装在之前设好的路径
下。编译并安装
make
make install
3.5 FFTW 3
FFTW(the Fastest Fourier Transform in the West)是一个C子程序库,用于计算一个或多个维度,任意输入大小,实数和复数数据的离散傅里叶变换(DFT) 首先下载压缩包 fftw-3.3.4.tar.gz[http://www.fftw.org/fftw-3.3.4.tar.gz]
解压压缩包并进入新产生的文件夹
配置
./configure --prefix=/opt/libraries/gnu8-fftw/3.3.8 CC="gcc" CFLAGS="-O3" F77="gfortran" F77FLAGS="-O3 -ffree-line-length-none"
编译并安装
make
make install
—————————————————————————————————————————————————
3.6 LibXC
这是一个密度泛函理论(
DFT
)的交换关联泛函库,其中你可以找到不同类型的泛函,例如:LDA
,GGA
,hybrids
和mGGA
。Libxc
库也可以用于Abinit
软件,目前最新版本为6.1.0
。首先下载压缩包 libxc-4.3.4.tar.gz[http://www.tddft.org/programs/octopus/down.php?file=libxc/4.3.4/libxc-4.3.4.tar.gz]
解压压缩包并进入新产生的文件夹
配置
./configure --prefix=/opt/libraries/gnu8-libxc/4.3.4 CC="gcc" CFLAGS="-O3" FC="gfortran" FCFLAGS="-O3 -ffree-line-length-none"
如果您没有使用稳定版本的tarball,您需要先使用“autoreconf -fi”生成configure文件。这个命令将重新生成configure文件,以便它可以适应您的环境和软件包的特定要求。在生成configure文件后,您可以运行“./configure”命令来配置软件包,并继续进行编译和安装。请注意,这个命令需要在源代码目录中运行,并且您需要安装autotools工具包才能使用它。
编译并安装
make
make install
4. 编译安装Octopus
4.1 Octopus 安装
编译完这些库后,我们可以开始编译Octopus了
首先下载最新版本的Octopus:octopus-12.2.tar.gz
解压压缩包并进入新产生的文件夹
定义几个环境变量,用来写配置脚本:
export LIBS_BLAS=/opt/libraries/gnu8-blas/3.10.0/lib/libblas.a
export LIBS_LAPACK=/opt/libraries/gnu8-lapack/3.9.1/lib/liblapack.a
export LIBS_FFT=/opt/libraries/gnu8-fftw/3.3.8/lib/libfftw3.a
接下来写配置脚本:
autoreconf -i
./configure --prefix=/opt/apps/octopus12.2 --with-gsl-prefix=/opt/libraries/gnu8-gsl/2.7 --with-libxc-prefix=/opt/libraries/gnu8-libxc/4.3.4
注:
configure
命令的参数解释之--with
:该参数指定了配置文件时去哪里寻找对应的库编译并安装
make
make install
如果一切都进展顺利的话,Octopus应该会成功安装在你一开始设定的
路径
文件夹内,可执行文件放在/opt/apps/octopus12.2
文件夹内,接下来将其路径添加到环境变量里,以便你可以只输入octopus
就可运行, 而非每次都要输入/opt/apps/octopus12.2/octopus
才行。
export PATH=$PATH:/opt/apps/octopus12.2/bin/octopus
最终整个软件的环境变量为(可能与前面的有差别,读者仔细阅读自行斟酌):
export LIBS_BLAS=/opt/libraries/gnu8-blas/3.10.0/lib/libblas.a
export LIBS_LAPACK=/opt/libraries/gnu8-lapack/3.9.1/lib/liblapack.a
export LIBS_FFT=/opt/libraries/gnu8-fftw/3.3.8/lib/libfftw3.a
export GSL_HOME=/opt/libraries/gnu8-gsl/2.7 && \
export PATH=$GSL_HOME/bin:$PATH && \
export LD_LIBRARY_PATH=$GSL_HOME/lib:$LD_LIBRARY_PATH && \
export LIBRARY_PATH=$GSL_HOME/lib:$LIBRARY_PATH && \
export INCLUDE=$GSL_HOME/include:$INCLUDE && \
export C_INCLUDE_PATH=$GSL_HOME/include:$C_INCLUDE_PATH && \
export MANPATH=$GSL_HOME/share/man:$MANPATH
export LIBXC_HOME=/opt/libraries/gnu8-libxc/4.3.4 && \
export PATH=$LIBXC_HOME/bin:$PATH && \
export LD_LIBRARY_PATH=$LIBXC_HOME/lib:$LD_LIBRARY_PATH && \
export LIBRARY_PATH=$LIBXC_HOME/lib:$LIBRARY_PATH && \
export INCLUDE=$LIBXC_HOME/include:$INCLUDE && \
export C_INCLUDE_PATH=$LIBXC_HOME/include:$C_INCLUDE_PATH && \
export OCTOPUS_HOME=/opt/apps/octopus12.2 && \
export PATH=$OCTOPUS_HOME/bin:$PATH && \
export LD_LIBRARY_PATH=$OCTOPUS_HOME/lib:$LD_LIBRARY_PATH && \
export INCLUDE=$OCTOPUS_HOME/include:$INCLUDE && \
export MANPATH=$OCTOPUS_HOME/share/man:$MANPATH
alias octopus='/opt/apps/octopus12.2/bin/octopus'
该软件的安装就完成了,接下来我们来测试一下。其中环境变量的设置可以写入
~/.bashrc
文件中,这样每次打开终端都会自动加载环境变量,不用每次都手动输入;也可以单独写为一个文件,之后使用软件时单独source
该文件即可。
4.2 简单例子运行测试
新建一空文件夹并进入,建立一个文件,命名为
inp
,并将其内容编辑为:
CalculationMode = gs
%Coordinates
'H' | 0 | 0 | 0
%
Spacing = 0.25 * angstrom
Radius = 4.0 * angstrom
注:文件只能命名为
inp
, Octopus 只识别这个输入文件名接下来试运行:
octopus &> output
即可运行octopus并将输出结果重定向到新建的 output 文件中。
将会在产生一个
output
文件的同时产生一些文件夹:exec
、restart
和static
。若只运行, 则输出会在屏幕上实时显示。
octopus
注:
&>
表示将标准输出和错误输出都重定向到文件中,若只想重定向标准输出,可以使用>
;若只想重定向错误输出,可以使用2>
。以下是
