Question

我将Mac OS与CLion IDE结合使用，我的任务是同时使用两个并行库（Open MP和MPI）。

问题是

module.exports.hello = async event => {
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'Go Serverless v1.0! Your function executed successfully!',
        input: event,
      },
      null,
      2
    ),
  };
};

我认为我无法弄清楚如何为其编写正确的CMakeLists。

我的CMakeLists如下：

Undefined symbols for architecture x86_64:
  "_MPI_Init", referenced from:
      _main in main.c.o
ld: symbol(s) not found for architecture x86_64
clang-9: error: linker command failed with exit code 1 (use -v to see invocation)

由于“偏好设置”中的C编译器是

cmake_minimum_required(VERSION 3.15.3)
project(SeqSol C)

set(CMAKE_C_COMPILER "/usr/local/opt/llvm/bin/clang")
set(CMAKE_CXX_COMPILER "/usr/local/opt/llvm/bin/clang++")
set(OPENMP_LIBRARIES "/usr/local/opt/llvm/lib")
set(OPENMP_INCLUDES "/usr/local/opt/llvm/include")

OPTION(USE_OpenMP "Use OpenMP to enable <omp.h>" ON)
OPTION(USE_MPI "Use MPI to enable <mpi.h>" ON)

# Find OpenMP
if (APPLE AND USE_OpenMP)
    if (CMAKE_C_COMPILER_ID MATCHES "Clang")
        set(OpenMP_C "${CMAKE_C_COMPILER}")
        set(OpenMP_C_FLAGS "-fopenmp=libomp -Wno-unused-command-line-argument")
        set(OpenMP_C_LIB_NAMES "libomp" "libgomp" "libiomp9")
        set(OpenMP_libomp_LIBRARY ${OpenMP_C_LIB_NAMES})
        set(OpenMP_libgomp_LIBRARY ${OpenMP_C_LIB_NAMES})
        set(OpenMP_libiomp9_LIBRARY ${OpenMP_C_LIB_NAMES})
    endif ()
    if (CMAKE_CXX_COMPILER_ID MATCHES "Clang")
        set(OpenMP_CXX "${CMAKE_CXX_COMPILER}")
        set(OpenMP_CXX_FLAGS "-fopenmp=libomp -Wno-unused-command-line-argument")
        set(OpenMP_CXX_LIB_NAMES "libomp" "libgomp" "libiomp9")
        set(OpenMP_libomp_LIBRARY ${OpenMP_CXX_LIB_NAMES})
        set(OpenMP_libgomp_LIBRARY ${OpenMP_CXX_LIB_NAMES})
        set(OpenMP_libiomp9_LIBRARY ${OpenMP_CXX_LIB_NAMES})
    endif ()
endif ()

if (USE_OpenMP)
    find_package(OpenMP REQUIRED)
endif (USE_OpenMP)

if (USE_MPI)
    find_package(MPI REQUIRED)
endif (USE_MPI)

if (MPI_FOUND)
    include_directories(${MPI_INCLUDES_PATH})
    link_directories(${MPI_LIBRARIES_PATH})
endif(MPI_FOUND)

if (OPENMP_FOUND)
    include_directories("${OPENMP_INCLUDES}")
    link_directories("${OPENMP_LIBRARIES}")
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
endif (OPENMP_FOUND)

add_executable(SeqSol main.c problem.c fileparse.c)

我也写了CMake选项：

/usr/local/opt/llvm/bin/clang

我可以使用Open MP功能，但是对于MPI来说是不可能的。

有什么建议吗？

我终于弄清楚了如何混合打开mp和mpi。此CMake文件对我有用

try:
    from tkinter import *
except ImportError:
    from Tkinter import *

try:
    import tkinter.ttk as ttk
    py3 = 1
except ImportError:
    import ttk
    py3 = 0

def create_window():
    global root, top
    root = Tk()            # creating a tkinter window, Tk is a class
    top = MainFrame(root)  # building the gui, so it's like MainFrame is inheriting the Tk class
    root.mainloop()        # infinite main loop

class MainFrame:
    def __init__(self, top=None):
        self.style = ttk.Style()
        if sys.platform == "win32":
            self.style.theme_use('winnative')

        top.geometry("802x557+250+104")
        top.minsize(120, 1)
        top.maxsize(2970, 881)
        top.resizable(0, 0)      # fixing the GUI size

        self.Labelframe = LabelFrame(top)
        self.Labelframe.place(relx=0.4, rely=0.4, relheight=0.279, relwidth=0.264)
        self.Labelframe.configure(text='''Test label''', background="#d9d9d9")


if __name__ == '__main__':
    create_window()

MPI + Open MP混合初始化
