Dear Jeff,
Great that you got it working!
The speedup of only 30% for 4 cores is probably due to the fact that the
example is too small for 4 cores. Once the simulation starts, there's no
Python overhead. For higher resolutions you will see more effect of using
multiple cores.
Kind regards,
Mart
I finally got it working. The problem seemed to be a few things. But the
tweaks below (some of which you recommended) seem to work fine:
-changed the "include" path in setup-mpi.py to link to a folder with the
files from meep-openmpi: meep.hpp and /meep/mympi.hpp and /meep/vec.hpp.
-in the "mee

I finally got it to compile with MPI support now. It worked once I was
able to install the packages just named "meep-mpi" and "libmeep-mpi-dev"
which were different from the "default" and "openmpi" versions.
Now it has another problem... when I execute a script with mpirun and the

Dear Jeff,
I'm not sure whether that's the problem, but the ImportError probably means
it cannot find your _meep_mpi.so file. This could be, again, because of
non-default locations. By the way, if I'm not mistaking _meep_mpi.so is not
a file from the ubuntu repository but a file that was generated
Thanks for your reply. I took your advice, and I found out that it
successfully compiled if I installed the Ubuntu packages
"libmeep-mpi-default-dev" and "meep-mpi-default", and then changed the
extension in the setup-mpi.py to "_meep_mpi-default" and the libraries var
to "meep_mpi-default".

Hello,
Sorry for the delay with maillist - the policy of Launchpad changed it
to be a moderated list a year or so ago.
The errors which you are facing are most probably caused by the meep
build. The first error you are mentioning is due to the meep's include

Hello,
I'm trying to build python-meep with MPI in Ubuntu 12.10, but keep getting
errors. I was able to successfully build and use it without MPI, so it
seems that most of the dependencies should be ok. I did go through the
readme and install all of the recommended files.
