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 mak
source for python script - it is not equivalent to 1.ctl
#!/usr/bin/python
import meep
import getopt
import sys
m=meep.MPI(sys.argv)
if meep.my_rank()==0:
print 'Count processors:', meep.count_processors(), 'My rank is',
meep.my_rank()
class epsilon(meep.Callback):

Dear Meep users !
Lately I was trying to implement pythonic interface for libmeep. My current
goal is enabling mpi feature of libmeep in python scripts. While enabling
mpi is as straight as just calling mpi_init with correct arguments, the
actual mpi acceleration do not meet my expectations. I did
