Dear Meep Users,
I am about to start running the most important simulation of my PhD:
There is this very complicated 3D structure consisting of 40 cosine-shape
structures on a block of dielectric (it will be expanded to bigger number).

So the first question is - what mpi efficiency do you observe on your

I have observed excellent acceleration. Dual-core systems have been
near-linear, and running on 8 machines with a GigE interconnect I got
about 6x acceleration.
The important thing is to make

MEEP does not simulate motion. In MEEP, all objects are fixed, and only
the electromagnetic field can change with time. Therefore, there is no
such thing as mass.

Hi, everyone:
We are considering for buying one PC to run MEEP .
The number of points in my usual case is around 125e+6, corresponding
to 5.722GB.
Additionally, we use dispersive material.
I use long wavelength

You are absolutely right.
The key, for posterity's sake, is to first generate a polarizability with the

Dear Meepers,
I am trying to define a polarizability with spatially varying sigma. My code
reads, in part:
