MITgcm移植指南

MITgcm官网软件介绍：

MITgcm 灵活的非流体静力学公式是为研究大气、海洋和气候而设计的数值模型，使其能够有效地模拟各种尺度的流体现象；它的伴随能力使其能够应用于敏感性问题以及参数和状态估计问题。通过采用流体方程同构，可以使用单个动力学核来模拟大气和海洋的流动。该模型的开发是为了在各种计算平台上高效执行。

wget https://github.com/MITgcm/MITgcm/archive/refs/tags/checkpoint67s.tar.gz
mv checkpoint67s.tar.gz MITGCM-2020-mid.tar.gz
tar xzvf MITGCM-2020-mid.tar.gz
cd MITgcm-checkpoint67s

安装

需要先进入build目录，然后使用genmake2生成Makefile

1
2
cd verification/exp2/build
../../../tools/genmake2 -mods ../code -optfile «/PATH/TO/OPTFILE» # ../../../tools/build_options/linux_amd64_gfortran

然后执行make等命令

1
2
make depend
make

在build目录下生成mitgcmuv，完成

mpi安装

mpi安装的官方文档

与上面的类似，只需要将genmake2命令替换为如下即可

1
2
3
../../../tools/genmake2 -mods=../code -mpi -of=«/PATH/TO/OPTFILE» # ../../../tools/build_options/linux_amd64_gfortran
make depend
make

openmp安装

openmp安装的官方文档

与上面的类似，只需要将genmake2命令替换为如下即可

1
2
3
../../../tools/genmake2 -mods=../code -omp -of=«/PATH/TO/OPTFILE» # ../../../tools/build_options/linux_amd64_gfortran
make depend
make
