comment How to compile procedural program effectively
@matheorem No. I'm not sure whether that's possible or not.

@matheorem As you have discovered, sometimes the compiler is smart enough to skip some computations. I don't want that to happen.

@matheorem Thanks for the test. I was using the intel compiler, but with optimization turned off.

comment FDTD Electromagnetic Simulations with Mathematica
I also used FDTD a couple of years ago in a paper. We solved the coupled Maxwell-Schrodinger equation. At the beginning I was doing everything in Mathematica, but moved to Fortran at the end. I agree with Jens that for production maybe you need more than Mathematica.

comment Numerical solution of Schrödinger equation
You may want to look at NDEigensystem which can solve eigensystem numerically for a differential operator. I have added a 1D example in the same link.
