intelMPI在ubuntu下面的编译方法

[李东岳]

1. 下载intelMPI https://www.jianguoyun.com/p/DX7jqOUQk_icChiq-a0E

2. 复制到Ubuntu系统下，运行.sh文件进行安装到任意文件夹，我的装到了这里：/home/dyfluid/intel/oneapi/mpi/2021.5.1/include

3. OpenFOAM-9/etc/basrhc: export WM_MPLIB=INTELMPI

4. OpenFOAM-9/etc/config.sh/mpi: export MPI_ROOT=/home/dyfluid/intel/oneapi/mpi/2021.5.1/include

5. source /home/dyfluid/intel/oneapi/setvars.sh
   source /home/dyfluid/OpenFOAM/OpenFOAM-9/etc/bashrc
   

6. 编译即可

因为看好多人都是用ICC+intelMPI，打算实测下用g++可以配套intelMPI使用不，实测可行。
