Use PyATS to connect to multiple devices

I am using the following python code to connect to a bunch of devices. Right now I am doing it one by one but it takes a lot of time, is there anyway to connec to multible devices at once and have it run the commands on them in parallel?

testbed = load("empty-testbed.yaml") for device in allDevices: # Helper function to add devices to the testbed dev = add_device(device.name, "ios", testbed, ip_addr=device.ip) dev.connect(log_stdout=False, connection_timeout=10) stp = dev.parse('show spanning-tree detail') instances = stp['mstp']['mst_instances']

Instead of looping through the list and run the commands one by one, I just want to add all devices to the testbed and have it run the commands on all devices at once.

you need to use multiprocess example :

make sure you enough process when you run same time multi processs, it may freeze CPU if you overload test with limited multi process.
