CESM的PMPI_Allgatherv(1072): Buffers must not be aliased问题

打怪兽的小队长

最近在尝试用再分析资料来驱动CESM。
但是无论如何也跑不通，出现满屏的如下报错：
PMPI_Allgatherv(1072): Buffers must not be aliased
Fatal error in PMPI_Allgatherv: Invalid buffer pointer, error stack:

查询了很多网页，也试了很多解决办法
例如 在env_mach_specific中设置 setenv MPICH_NO_BUFFER_ALIAS_CHECK TRUE 以及 setenv I_MPI_COMPATIBILITY 4 无法解决问题
在环境变量中设置 export MP_EUIDEVELOP=min 也依然无法解决。
十分苦恼，有没有大神知道还有没有别的解决办法？

解决：疯狂尝试不同环境配置（最终成功的是 intel14 加 mpi2.1.5）还有可能是MERRA的路径没写对（我的多了一个空格就报错）

先按你的方法试试

也可能是compset的问题，换了一个就没事了
