Dear all,
When I recently run the mpi version of meep, I have a problem that when I
type: mpirun -np 4 meep-mpi ***.ctl, it returns
using MPI version 2.0, 1 processes
using MPI version 2.0, 1 processes
using MPI version 2.0, 1 processes
using MPI version 2.0, 1 processes
.
It seems

Hi,
Nizamov Shawkat, thank your for your reply and conforming not 1 to 1 scaling
of meep stepping for MPI on your setup.
I`ve checked scaling from problem size on two systems. Results are in LaTeX
format at the end of my letter. You can
Hi,
I`ve continued benchmarking meep 1.1.1, now on a single 2 CPU (4 cores each)
host to exclude my network setup...
Simulating drop filter.

Dear all,Does anyone know how I can run my simulation with a multiprocessor
system to get a faster run?I have installed meep-mpi and mpich2 on my ubuntu.
For a parallel meep running I do steps below,1) I type mpd in terminal2) I
type mpirun -np 8 meep-mpi test.ctl in terminal.It
starts
Hello,
MPI requires an overhead (of passing data between the processors, etc.). For
short simulations you might not gain (wallclock) time at all, or even lose
some.
Try a long / large simulation and see if it has any effect.
Good luck and regards,
Georg
