构建MPI程序时出错 [英] Error in building MPI program

问题描述

我是MPI的新手。我试图编写一个用MPI和FORTRAN计算PI的程序。但是，当我尝试构建程序时，我收到以下消息。

  make all 
 gfortran -O2 -g \\ \\ 
 -o bin / MpiTest.exe \ 
 src / MpiTest.f -fno-range-check 
 C：/ Program Files / MicrosoftMPI / Inc / mpif.h：344.38：
包含在src / MpiTest.f中：11：
 
 PARAMETER（MPI_AINT = z'4c00043b'）
 1 
错误：'mpi_aint'的PARAMETER属性与PARAMETER冲突属性在（1）
 C：/ Program Files / MicrosoftMPI / Inc / mpif.h：359.35：
包含在src / MpiTest.f中：11：
 
 PARAMETER（MPI_ADDRESS_KIND = INT_PTR_KIND（））
 1 
错误：在（1）初始化表达式中的函数'int_ptr_kind'必须是内部函数
 make：*** [all]错误1 
  

任何人都可以帮我吗？

  PROGRAM CAL culatePI 
包含C：/ Program Files / MicrosoftMPI / Inc / mpif.h
 
 INTEGER :: i = 0，nThrows = 0，nSuccess = 0，ierror = 0，numOfProcessors = 0，myID = 0 
 REAL :: x = 0，y = 0，results = 0 
 
 INTEGER :: Counter = 0 
 
 call mpi_init（ierror） 
调用mpi_comm_rank（MPI_COMM_WORLD，myID，ierror）
调用mpi_comm_size（MPI_COMM_WORLD，numOfProcessors，ierror）
 .... 
  

解决方案

INT_PTR_KIND 是英特尔Fortran编译器扩展功能;也就是说，它不是Fortran的内在。您报告的第二条错误消息表明，在编译包含对其无法找到的函数的引用的代码时， gfortran 会阻挠。我猜第一个错误是出于同样的问题，你正试图用'错误的'编译器进行编译。

正如Alexander Vogt所建议的，使用编译器包装器，如 mpif90 ，但它必须是正确的包装器，即调用gfortran并与MS MPI库链接的包装器。不知道这个包装是否存在我不知道，但是在 C：/ Program Files / MicrosoftMPI / 下查找。

但是，由于这些错误来自你包含的 mpif.h 文件，你还必须找到一个相应的包含文件来编译 gfortran 。我不使用MS MPI，但如果您发现它只提供用于与英特尔Fortran编译的工具，库和包含文件，则不会感到意外。

I'm new to MPI. I'm trying to write a program for calculating PI using MPI and FORTRAN. But when I try to build the program I get the following messages.

make all
 gfortran -O2 -g \
    -o bin/MpiTest.exe \

Error: Function 'int_ptr_kind' in initialization expression at (1) must be an intrinsic function

Can anyone help me here ?

P.S :

PROGRAM CalculatePI
        include "C:/Program Files/MicrosoftMPI/Inc/mpif.h"

            INTEGER :: i = 0, nThrows = 0, nSuccess = 0, ierror =0, numOfProcessors=0,myID=0
            REAL :: x = 0, y = 0, results = 0

            INTEGER :: Counter = 0

            call mpi_init(ierror)
            call mpi_comm_rank(MPI_COMM_WORLD, myID, ierror)
            call mpi_comm_size(MPI_COMM_WORLD, numOfProcessors, ierror)
            ....

解决方案

INT_PTR_KIND is an Intel Fortran compiler extension function; that is, it is not a Fortran intrinsic. The second of the error messages that you report indicates that gfortran is baulking at compiling code which contains references to a function it can't find. I guess the first error arises from the same problem, you are trying to compile with the 'wrong' compiler.

As Alexander Vogt has suggested you might make better progress using a compiler wrapper such as mpif90, but it has to be the right wrapper, the one which calls gfortran and links with the MS MPI library. Whether that wrapper exists I do not know, but look for it under C:/Program Files/MicrosoftMPI/.

However, since those errors emanate from the mpif.h file you have included you'll also have to find a corresponding include file for compiling with gfortran. I don't use MS MPI but it won't surprise me if you find that it only provides tools, libraries and include files for compilation with Intel Fortran.
