Dear Steven and meep users, Thank you very much for your advice and comments.
I tried to recompile openmpi, but no effect. Using --without-gcc-arch flag when I configure Meep(1.0.1), the compile succeeded, however, the calculation speed was extraordinary slow. I use FreeBSD7.2 - i386 and under the circumstances, meep-0.20.4 (with openmpi) works perfectly.

That sounds like a compiler bug - the compiler should never emit assembly instructions that are unrecognized by the assembler. Or, more likely, it's a problem with the installation of your compilers (or openmpi, or your assembler/binutils). You may want to reinstall openmpi, if you installed it from source code. If you installed it from a precompiled package that came with your system (Ubuntu? Fedora? and what architecture? ....you need to provide more information...) then you may want to complain to the vendor. Try passing the --without-gcc-arch flag when you configure Meep, to see if the -march flag is somehow interacting badly with openmpi.
