WRF | 库的安装
**介绍**
```bash
库的版本
mpich-3.0.4
zlib-1.2.7
libpng-1.2.50
jasper-1.900.1
hdf5-1.10.5
netcdf-c-4.8.1
netcdf-fortran-4.5.4
netcdf-cxx4-4.3.1
openmpi-3.0.0
编译器版本
编译器使用的是gun
gfortran的版本最好不要高于7，因为fortran大于7的版本中iand函数的定义变了
可能会报intmath的错。
```
**文件所用脚本**
```bash
gfortran是Fortran 95 编译器，支持Fortran95和一部分Fortran2003的功能
which gfortran
/usr/bin/gcc
which cpp
/usr/bin/cpp
gcc是GCC中的GUN C Compiler（C 编译器）
which gcc
/usr/bin/gcc
查看gcc版本
gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

Ps: 编译器和库测试
mpi和opempi
编译时的选择
serial
表示串行计算；
smpar
表示内存共享并行计算(shared memory option)，即使用openMP，大部分多核电脑都支持这项功能；
dmpar 表示分布式并行计算(distributed memory option)，即使用MPI 进行并行计算
，主要用在计算集群，单个电脑就没必要用了；
dm+sm 表示同时使用openMP与MPI两种并行方式.
mpich和openmpi的区别
openmpi是共享式内存结构上的并行计算，就是一台服务器上的多个线程的并行计算
mpich则是分布式内存结构的并行计算，由很多个服务器共同并行计算，是塔式结构。
上述两种并行库对模型计算有影响吗？当然是有的。WRF中的AFWA模块主要是用来诊断降水，极端天气，能见度，水汽，冰，云，热，湍流等的一些变量。如果需要打开这个模块，那么需要保证并行库是mpich的，否则会报错。
