我正在尝试将我的 fortran 代码分成几个部分，并且我想通过使用 MPI 来并行化每个部分。对于每个部分，我使用 IMSL 库来解决优化问题（使用 BCONF）。但是，我发现 IMSL 库有自己的关于 MPI 的子例程，它不允许我调用标准 MPI 启动子例程“Call MPI_INIT(ierror)”。它只是给我一个致命错误并结束程序。

我举两个例子来说明这个问题。

示例 1，从每个节点打印“Hello World”：

program main
use mpi
implicit none
integer ( kind = 4 ) error
integer ( kind = 4 ) id
integer ( kind = 4 ) p
call MPI_Init ( error )
call MPI_Comm_size ( MPI_COMM_WORLD, p, error )
call MPI_Comm_rank ( MPI_COMM_WORLD, id, error )
write ( *, * ) ' Process ', id, ' says "Hello, world!"'
call MPI_Finalize ( error )
end program

当我在没有 IMSL 库的情况下编译和运行时，它给了我正确的答案：

mpif90 -o a.out hello_mpi.f90
mpiexec -n 4 ./a.out

Process 3 says "Hello, world!"
Process 0 says "Hello, world!"
Process 2 says "Hello, world!"
Process 1 says "Hello, world!"

现在，如果我对代码没有任何更改，而只是添加 IMSL 库，则会导致错误：

mpif90 -o a.out hello_mpi.f90 $LINK_FNL_STATIC_IMSL $F90FLAGS
mpiexec -n 4 ./a.out

*** FATAL ERROR 1 from MPI_INIT. A CALL was executed using the IMSL
*** FATAL ERROR 1 from MPI_INIT. A CALL was executed using the IMSL
*** FATAL ERROR 1 from MPI_INIT. A CALL was executed using the IMSL

*** library.
*** dummy routine. Parallel performance needs a functioning MPI
*** library.
*** FATAL ERROR 1 from MPI_INIT. A CALL was executed using the IMSL
*** dummy routine. Parallel performance needs a functioning MPI
*** library.

在第一个示例中，将“$LINK_FNL_STATIC_IMSL”更改为“LINK_MPI”将解决问题，但在此处更实际的示例中它不起作用：

示例2：使用MPI，每个节点使用IMSL库计算正交节点

program main
USE GQRUL_INT
use mpi
implicit none
integer ( kind = 4 ) error
integer ( kind = 4 ) id
integer ( kind = 4 ) p
real ( kind = 8 ) QW(10), QX(10)
call MPI_Init ( error )
call MPI_Comm_size ( MPI_COMM_WORLD, p, error )
call MPI_Comm_rank ( MPI_COMM_WORLD, id, error )
write ( *, * ) ' Process ', id, ' says "Hello, world!"'
CALL GQRUL (10, QX, QW )
call MPI_Finalize ( error )
end program

当我编译并运行时，程序在“MPI_INIT”处停止：

mpif90 -o a.out hello_mpi.f90 $LINK_FNL_STATIC_IMSL $F90FLAGS
mpiexec -n 4 ./a.out 

*** FATAL ERROR 1 from MPI_INIT. A CALL was executed using the IMSL
*** dummy routine. Parallel performance needs a functioning MPI
*** library.
*** FATAL ERROR 1 from MPI_INIT. A CALL was executed using the IMSL
*** dummy routine. Parallel performance needs a functioning MPI

*** FATAL ERROR 1 from MPI_INIT. A CALL was executed using the IMSL
*** dummy routine. Parallel performance needs a functioning MPI
*** library.
*** dummy routine. Parallel performance needs a functioning MPI
*** library.

如果我将链接选项更改为 $LINK_MPI，程序会在 IMSL 库子例程处崩溃：

mpif90 -o a.out hello_mpi.f90 $LINK_MPI $F90FLAGS
mpiexec -n 4 ./a.out

Process 1 says "Hello, world!"
Process 0 says "Hello, world!"
Process 3 says "Hello, world!"
Process 2 says "Hello, world!"

我在学校的超级计算机上的 UNIX 系统上运行此代码，我使用的是英特尔编译器和 MPICH 3.0.1 版。我的实际代码与第二个示例非常相似，它在每个节点上使用了一些 IMSL 子例程。你能帮我让它工作吗？谢谢！

最后，d_1999提供了一个链接，它为我提供了足够的信息来解决这个问题。我只需要将链接标志更改为 $LINK_MPIS，然后我就可以毫无问题地运行第二个示例代码。
