以下是一个简单的 MPI C++ 程序示例,使用 mpicxx 编译: 代码语言:txt 复制 #include <mpi.h> #include <iostream> int main(int argc, char** argv) { MPI_Init(&argc, &argv); int world_size; MPI_Comm_size(MPI_COMM_WORLD, &world_size); int
find_package(MPI REQUIRED) include_directories(${MPI_INCLUDE_PATH}) set(CMAKE_CXX_COMPILER mpicxx) set(CMAKE_C_COMPILER mpicc) add_executable(MPI main.cpp) 测试代码: # include "mpi_hello.h" # include "cstdio" # include "cstring" # include "mpi.h" const int MAX_STRING = 100; int ...
set( CMAKE_BUILD_TYPE "Debug") # include_directories("/usr/lib/x86_64-linux-gnu/openmpi/include") include_directories(SYSTEM ${MPI_INCLUDE_PATH}) add_executable(hello-mpi hello-mpi.cpp) target_link_libraries(hello-mpi ${MPI_CXX_LIBRARIES}) # this must be MPI_CXX_LIBRARIES for cpp file...

针对你遇到的“could not find mpi_cxx (missing: mpi_cxx_lib_names mpi_cxx_header_dir mpi_cxx_works)”问题,可以按照以下步骤进行排查和解决: 检查MPI库是否已正确安装: 确保你的系统上已经安装了支持C++的MPI库,如Open MPI或MPICH。 你可以通过运行以下命令来检查MPI库的安装情况(以Open MPI为例): bas...
VC++目录->包含目录,添加:“C:\Program Files %28x86%29\Microsoft SDKs\MPI\Include;” VC++目录->库目录,添加:“C:\Program Files %28x86%29\Microsoft SDKs\MPI\Lib\x64;” C/C++ -> 预处理器->预处理器定义,添加:“MPICH_SKIP_MPICXX;” ...
以MacOS为例，可以使用以下指令完成这个操作$echo"exportPATH=【MPI安装目录】/bin/:$PATH">>~/.bash_profile之后用以下指令打开bash profile，$ vim ~/.bash_profile如果MPI的安装目录包括在bash profile中，表明MPI已经写入了bash profile中。6 这里还可以用which指令检查mpicxx和mpicc两个指令来检查MPI是否安装...
