我试图将我的fortran代码分成几个部分，我想通过使用MPI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MPI子程序，它不允许我调用标准的MPI启动子程序“Call MPI_INIT（ierror）”。它只是给了我一个致命的错误并结束了程序。
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，它给出了正确的答案：
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，如果我没有对代码进行任何更改，只是添加了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

*** 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”可以解决问题，但在此处的实际示例中不起作用：
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
编译运行时，程序停在“MPI_INIT”：
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

*** 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，程序将在IMSL库子例程崩溃：
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!"

我在我学校的超级计算机上的UNIX系统上运行此代码，我正在使用intel编译器和MPICH版本3.0.1。我的实际代码与第二个示例非常相似，后者在每个节点上使用一些IMSL子例程。你能帮助我让它发挥作用吗？谢谢！
