Qinghua,

The reason to use ia32 version of the compiler is that your operating
system is in 32bit.

I am not sure if openmpi could possibly interfere your PMEMD building
procedure, but a wrong MPI_HOME setting sure does. Try to make sure
that MPI_HOME is pointing to the right path of your lammpi.

Nevertheless you can try to use "rpm -qa | grep -i openmpi" to figure
out the name of the openmpi package and use "rpm -e <the package
name>" to remove the package.

Although you probably don't need too much extra information, I just
tested this on an ia32 fedora core 4 box. Here is how I built it:

         I have a clean amber10 in my ~/src/amber10, enter the directory
         of amber10/src. Then I did "env MKL_HOME=/opt/intel/mkl/8.0.1
        ./configure_amber -lamsource -p4 -nosanderidc". After that I ran
        the script of ./configure_lam. Waited a while since it costs some
        minutes to do it. Having lammpi installed in ~/src/amber10, you
        need to have your MPI_HOME environment variable pointing to the
        directory ~/src/amber10, and run the configuration in pmemd
        directory. "./configure linux_p4 ifort lam nobintraj" is what I
        did (nobintraj is not relevant). I was able to make install
        WITHOUT PROBLEM. Note that you don't have to compile your own
        lammpi, what I wanted to do is to make sure every factor is
        under my control.
