安装不同版本的mpi库
sudo yum install -y openmpi-1.10.x86_64 openmpi-1.10-devel.x86_64 sudo yum install -y openmpi-1.8.x86_64 openmpi-1.8-devel.x86_64 sudo yum install -y mpich2.x86_64 mpich2-devel.x86_64 |
安装modules
sudo yum install -y environment-modules
使用module管理库
使用 module avail 查看当前可用的库
$ module avail --------------------------------- /usr/share/Modules/modulefiles ---------------------------------- dot module-git module-info modules null use.own ---------------------------------------- /etc/modulefiles ----------------------------------------- mpich-x86_64 openmpi-1.10-x86_64 openmpi-1.8-x86_64 openmpi-x86_64 |
使用 module list 查看当前已经加载的库
$ module list
# 如果已经使用 module load 加载了库，查看结果如下：
$ module load openmpi-1.10-x86_64
$ module list
Currently Loaded Modulefiles:
1) openmpi-1.10-x86_64
使用 module load/unload 加载和卸载库
$ module load openmpi-1.10-x86_64
$ module list
Currently Loaded Modulefiles:
1) openmpi-1.10-x86_64
$ module unload openmpi-1.10-x86_64
添加自定义模块
从 “module avail” 命令结果可以看到在 /etc/modulefiles 目录下保存着各个mpi的配置信息，下面是openmpi-1.10-x86_64的配置内容。
#%Module 1.0 # # OpenMPI module for use with 'environment-modules' package: # conflict mpi prepend-path PATH /usr/lib64/openmpi-1.10/bin prepend-path LD_LIBRARY_PATH /usr/lib64/openmpi-1.10/lib prepend-path PYTHONPATH /usr/lib64/python2.6/site-packages/openmpi-1.10 prepend-path MANPATH /usr/share/man/openmpi-1.10-x86_64 setenv MPI_BIN /usr/lib64/openmpi-1.10/bin setenv MPI_SYSCONFIG /etc/openmpi-1.10-x86_64 setenv MPI_FORTRAN_MOD_DIR /usr/lib64/gfortran/modules/openmpi-1.10-x86_64 setenv MPI_INCLUDE /usr/include/openmpi-1.10-x86_64 setenv MPI_LIB /usr/lib64/openmpi-1.10/lib setenv MPI_MAN /usr/share/man/openmpi-1.10-x86_64 setenv MPI_PYTHON_SITEARCH /usr/lib64/python2.6/site-packages/openmpi-1.10 setenv MPI_COMPILER openmpi-x86_64 setenv MPI_SUFFIX _openmpi setenv MPI_HOME /usr/lib64/openmpi-1.10 |
因此，对于自己手动安装的mpi版本，可以根据上面的配置来写一个新的版本，比如我新加一个/etc/modulefiles/myopenmpi文件，将其中的路径指定我自己安装的openmpi路径/opt/openmpi上，文件看起来如下：
#%Module 1.0 # # OpenMPI module for use with 'environment-modules' package: # conflict mpi prepend-path PATH /opt/openmpi/bin prepend-path LD_LIBRARY_PATH /opt/openmpi/lib prepend-path PYTHONPATH /usr/lib64/python2.6/site-packages/openmpi-1.10 prepend-path MANPATH /opt/openmpi/share/man setenv MPI_BIN /opt/openmpi/bin setenv MPI_SYSCONFIG /etc/myopenmpi-1.10-x86_64 setenv MPI_FORTRAN_MOD_DIR /usr/lib64/gfortran/modules/openmpi-1.10-x86_64 setenv MPI_INCLUDE /opt/openmpi/include setenv MPI_LIB /opt/openmpi/lib setenv MPI_MAN /opt/openmpi/share/man setenv MPI_PYTHON_SITEARCH /usr/lib64/python2.6/site-packages/openmpi-1.10 setenv MPI_COMPILER openmpi-x86_64 setenv MPI_SUFFIX _openmpi setenv MPI_HOME /opt/openmpi |
然后就可以在 “module avail” 中看到这个新添加的版本了。
