Have a look at the modeller.parallel module and friends:
http://salilab.org/modeller/manual/node69.html
http://salilab.org/modeller/manual/node408.html#SECTION:parallel
As an example, you need to have something like this:
from modeller import * # Load standard Modeller classes
from modeller.automodel import * # Load the automodel class
from modeller.parallel import * # Load the parallel class, to use multiple processors
j = job(modeller_path=os.path.join(modellerPath, "bin/modslave.py"))
j.append(local_slave()) # 1 Processor
j.append(local_slave()) # 2 Processors
j.append(local_slave()) # 3 Processors...and so on
env = environ()
..... Regular Modeller definitions.....
a.use_parallel_job(j) # Use the job for model building
a.make() # do the actual homology modeling
