ipyparallel, how to set process numbers of a node

Question

I know I can start my engine by ipengine --profile=/path/to/ipcontroller-engine.json. And there are len(c.ids) processes.

But, how can I set the numbers of processes running on every remote node? It seems that ipengine --profile=/path/to/ipcontroller-engine.json is just launch just one process on remote machine.

ipengine starts one engine (process). If you want multiple engines, you need to call ipengine multiple times. One shortcut for this is the ipcluster engines command:

ipcluster engines -n 4

will start 4 engines.

Is there also a way of specifying this number from within Python? – anilbey Jul 08 '20 at 08:46
