Support executing multiple process in parallel #5

Open chinnikrishna opened 5 years ago

chinnikrishna commented 5 years ago

Hi, Is there support to execute multiple process within same environment in parallel? If there is no support can you outline what it takes to enable such a support? Thanks

Hi,

Please take a look at this example: https://simpy.readthedocs.io/en/latest/examples/process_communication.html

The last part features 3 processes: one message_generator, and two message_consumer.

I am sorry I was not clear. Is there someway to execute two different process on two different processors? For example use python multiprocessing and offload that process to a different core (I did follow the parallel python tutorial here https://pythonhosted.org/SimPy/Manuals/Interfacing/ParallelSimPy/SimPyPP.html but we want find module listing in our infrastructure hard) Can you suggest any alternatives based on new python multiprocessing module

If you want to run the same simulation code with multiple parameters, then you can use the shell to run them in parallel:

./simulate --seed 1 &
./simulate --seed 2 &
...
wait

I never needed to parallelize "within" simulation.

Hope it helps.
