If you are to use such an ancient compiler (apparently a 32-bit one),
you must read the docs which come with it, rather than relying on
comments about a more recent version. libsvml isn't included
automatically at link time by that 32-bit compiler, unless you specify
an SSE option, such as -xW.
It's likely that no one has verified OpenMPI with a compiler of that
vintage. We never used the 32-bit compiler for MPI, and we encountered
run-time library bugs for the ifort x86_64 which weren't fixed until
later versions.
