Help: About Intel Fortran Compiler:

  Hi, All:
  I tried to compile a Fortran 90 MPI program by
the Intel Frotran Compiler in the OSCAR cluster.
  I run the command:
"
ifc -I /opt/mpich-1.2.5/include -Lmpi -w -Lm -o p_wg3 p_fdtd3dwg3_pml.f90
"
 The system failed to compile it and gave me the following information:
"
   module EHFIELD
   program FDTD3DPML
   external function RISEF
   external function WINDOWFUNCTION
   external function SIGMA
   external function GETISTART
   external function GETIEND
   external subroutine COM_EYZ
   external subroutine COM_EYX
   external subroutine COM_EZX
   external subroutine COM_EZY
   external subroutine COM_HYZ
   external subroutine COM_HYX
   external subroutine COM_HZX
   external subroutine COM_HZY

At the same time, I tried the same program in the other scyld cluster,
using NAG compiler.

I use command:
"
f95 -I/usr/include -lmpi -lm -o p_wg3 p_fdtd3dwg3.f90
"

It works fine. So that means my fortran program in fine.

Both of the cluster use the MPICH implementation.

But because I have to work on that OSCAR cluster with Intel compiler,
I wonder
1. why the errors happen?
2. Is the problem of cluster or the Intel compiler?
3. How I can solve it.

I know there are a lot of guy with experience and experts of cluster and
MPI in this mailing list. I appreciate your suggestion and advice from
you.

Thanks.

Tom
