overture软件安装（串行版本）
Overture软件简介
Overture是一套基于面向对象技术设计的求解偏微分方程的数值计算软件，它为用户完成数值求解各种类型偏微分方程问题（特别是流体力学问题）提供了一套可移植的、灵活的开发平台。Overture内建支持有限差分和有限体积法等常用的数值计算方法，并且支持多重网格法。Overture是一套融合了网格生成，差分计算，边界条件设定，数据存取和图形显示等功能的综合型数值计算软件。

软件的安装
1. Open motif的安装
yum install openmotif yum install openmotif-devel
motif介绍 http://blog.csdn.net/mathlover/article/details/416298
2. Mesa OpenGL的安装
tar xzf MesaLib-XXX.tar tar xzf MesaDemos-XXX.tar.gz tar xzf MesaGLUT-XXX.tar.gz cd Mesa-XXX make 从结果中选一个与机器配置的类型，比如我的机器是linux64位的，就选择linux-x86-64 make linux-x86-64
在安装过程中可能缺少某些库，可以把缺少的库都安好在进行OpenGL的安装
yum install gtk* yum install Xorg yum install libdrm-devel yum install expat-devel
在bash终端里进行安装!
3. HDF的安装
tar xzf hdf5-XXX.tar.gz mv hdf5-XXX hdf5 cd hdf5 unsetenv CC unsetenv cc setenv CC gcc ./configure -prefix=当前工作目录 make make install
HDF在csh下进行安装，hdf5官网 http://www.hdfgroup.org/HDF5/
4. A++的安装
gzip -d AP-nnn.tar.gz tar -xf AP-nnn.tar cd A++P++nnn ./configure --enable-SHARED_LIBS --prefix=当前工作目录 make make install
A++是串行矩阵类。具体可参见https://computation.llnl.gov/casc/Overture/henshaw/documentation/App/manual/manual.html
5.LAPACK的安装
tar xzf lapack.tgz cd LAPACK
将INSTALL目录下的make.inc.LINUX文件复制到主文件夹并将其名改为make.inc
例如:
cp INSTALL/make.inc.LINUX make.inc
编辑make.inc文件，选择正确的编译器和编译选项，这里我用的是gfortran
生成库BLAS
make blaslib
生成库LAPACK
make lapacklib
将这两个库的名称进行更改
mv ./blas_LINUX.a ./libblas.a mv ./lapack_LINUX.a ./liblapack.a
6.PETSc的安装
tar xzf petsc-lite-2.3.2-p3.tar.gz mv petsc-2.3.2-p3 petsc-2.3.2 cd petsc-2.3.2 setenv PETSC_DIR 当前工作目录 setenv PETSC_ARCH linux-gnu-opt setenv PETSC_LIB $PETSC_DIR/lib/$PETSC_ARCH setenv CC gcc ./config/configure.py -PETSC_ARCH=linux-gnu-opt -with-debugging=0 -with-fortran=0 -with-matlab=0 -with-mpi=0 -with-shared=1 -with-dynamic=1 --download-c-blas-lapack=1 make
Overture使用PETSc求解稀疏矩阵，具体内容可参见其官网http://www.mcs.anl.gov/petsc/
7. Overture串行版本的安装
tar xzf Overture.XXX.tar cd Overture.XXX
编辑文件defenv，更改里面的环境变量，具体更改如下:
setenv XLIBS xxx
xxx目录包含有X window 系统的头文件目录(include)和库文件目录(lib)。当使用ls $XLIBS/lib查看时，应该可以看到libX11.so或是libX11.a文件。
setenv OpenGL xxx
当你用ls $OpenGL/lib查看时，可以看到文件libGL.so或libGL.a。如果你使用Mesa你将会看到libMesaGL.so或是libMesaGL.a文件。
setenv MOTIF xxx
如果你用ls $MOTIF/lib查看时，你应看到libXm.so或是libXm.a文件。
setenv HDF xxx
如果你用ls $HDF查看时，你应看到HDF目录中包含有include和lib目录。
setenv APlusPlus xxx
如果你用ls $APlusPlus 查看时，你应看到A++目录中包含有include和lib目录。
setenv Overture xxx
Overture软件安装的位置。
setenv CG xxx
如果你安装CG求解器，这个目录是CG文件解压后的件夹路径，这里不要改成别的路径否则在安装CG求解器时无法编译。
setenv CGBUILDPREFIX xxx
这是存放CG可执行文件和目标文件的位置，这个可以自己指定。
setenv LAPACK xxx
CG求解器需要LAPACK和BLAS的库。这个变量指向的目录含有liblapack.a和libblas.a的库文件。
setenv LD_LIBRARY_PATH ${MOTIF}/lib:${XLIBS}/lib:${HDF}/lib:${OpenGL}/lib:${Overture}/lib:${APlusPlus}/lib
当运行Overture里，Overture程序会自动加载这些库文件。有的可能lib要改为lib64对于64位的系统来说，具体可在库里面查看是放在lib下还是在lib64下。
更改后，将文件保存。
终端类型改为csh下的root用户后
surce defenv setenv LANG en_US perl configure make
安装要约要30分钟左右，安可后可用./check.p进行测试。
安装成功

我的defenv文件内容:
#! /bin/csh -f

#Define environment variables for Overture
#
# see the install notes on the web for further explanation or Overture/doc/install.tex
#
# edit this file and change as appropriate for your system,
# then type 'source defenv'
# You will need to change the following:
setenv XLIBS /usr
setenv MOTIF /usr
setenv OpenGL /home/soldier/Documents/overture5/mesa/Mesa-7.2
setenv HDF /home/soldier/Documents/overture5/hdf5
#PETSC的变量自己加进来，一共是3个
setenv PETSC_DIR /opt/overture/petsc-2.3.2-p6

# Here are variables to set if you intend to build CG
# CG : location for CG (source tree)
# CGBUILDPREFIX : location of CG executables (compile tree). This can be the same as CG
# if you only intend to build one version of CG.
# LAPACK : location of the LAPACK library
setenv CG /home/soldier/Documents/overture5/cg2.5
setenv CGBUILDPREFIX /home/soldier/Documents/overture5/cg2.5/cg2.5d
# In the following example LAPACK is found with the PGI compilers

# The LD_LIBRARY_PATH indicates the places to look for dynamic libraries. This variable should

关于环境变量的说明：
可以将环境变量写在/etc/csh.cshrc里面，这样每次打开csh时变量都已经定义好了。我的/etc/csh.cshrc里面的内容如下所示（这次Overture安装在/opt目录下）:
# /etc/cshrc
#
# csh configuration for all shell invocations.
# By default, we want this to get set.
# Even for non-interactive, non-login shells.
# Current threshold for system reserved uid/gids is 200
# You could check uidgid reservation validity in
# /usr/share/doc/setup-*/uidgid file

umask 002

umask 022
endif

endif

endif
endif
setenv MAIL "/var/spool/mail/$USER"

if (! $?loginsh) then

if ( -r "$i" ) then
if ($?prompt) then

7. CG(Composite Grid)求解器串行版本的安装
环境变量设置与Overture一样，如果上面的环境变量已经设定好就不进在进行设置了。
tar zxf cg.XXX.tar cd cg.XXX make安装好后，可以在cg主目录下用 make check 进行测试。
