Hi, I just upgraded to Intel MPI 2021.6.0 and discovered that a call to the function MPI_Get_library_version is returning: Intel(R) MPI Library
I just noticed that the mpi.h file included with 2019 release is missing any #define that helps to detect the mpi flavor used like former I_MPI_VERSION #define. The wrong thing is that, when calling the MPI_Get_library_version function, the output is: Intel(R) MPI ...

stephey@nid200185:~/openmpi> python -c "from mpi4py import MPI;print(MPI.Get_library_version())" Open MPI v5.0.0rc12, package: Open MPI ncicd@login01 Distribution, ident: 5.0.0rc12, repo rev: v5.0.0rc12, May 19, 2023
MPI_Get_library_version can currently be used to identify an implementation, but it is not well specified as a C ABI as it is not possible to determine the following without parsing a header file: the size of the buffer to allocate (i.e. the value of MPI_MAX_LIBRARY_VERSION_STRING fro...

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH 注意:LD_LIBRARY_PATH一定也需要配置,我在这个地方卡了蛮久,不配置LD_LIBRARY_PATH可能会出现段错误的问题。简单分析,就是调用了其他MPI的动态库,导致出现问题。 错误信息类似如下: $ mpirun -np 4 ./mpi_share/mpi_hello ...
