我使用的是cmake 3.10.2。我安装了 openmpi 和 mpich。不过我只需要加载 mpich.所以我从文档中找到了以下内容
A suffix which is appended to all names that are being looked for. For instance you may set this to .mpich or .openmpi to prefer the one or the other on Debian and its derivatives.
我的 CMake 文件是这样的
set(MPI_EXECUTABLE_SUFFIX ".mpich")
FIND_PACKAGE(MPI REQUIRED)
INCLUDE_DIRECTORIES(${MPI_INCLUDE_DIRS})
LINK_DIRECTORIES(${MPI_LIBRARY_DIRS})
message(${MPI_INCLUDE_PATH})
但是这表明
/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/usr/lib/x86_64-linux-gnu/openmpi/include...
我哪里出错了。你能帮我解决这个问题吗
还有
mpicc -show
gcc -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/opal/mca/event/libevent2022/libevent -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/opal/mca/event/libevent2022/libevent/include -I/usr/lib/x86_64-linux-gnu/openmpi/include -pthread -L/usr//lib -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi
mpicc.mpich -show
gcc -Wl,-Bsymbolic-functions -Wl,-z,relro -I/usr/include/mpich -L/usr/lib/x86_64-linux-gnu -lmpich
最佳答案
最好是使用模块在 openmpi 和 mpich 之间切换:
$ module load mpich
$ module unload mpich
$ module load openmpi
