Meanwhile, you can use subprocesses instead of threads to run your CPU-bound Python code in parallel. This has always been the officially recommended way to do parallel processing in Python. You’ll learn more about Python’s process-based parallelism in the next section....
create and manageevent loops, which provide asynchronous APIs fornetworking, runningsubprocesses, handlingOSsignals, etc; implement efficient protocols usingtransports; bridgecallback-based libraries and code with async/await syntax. 线程or进程模式 https://docs.python.org/3/library/asyncio-eventloop.html...
Parallel processing is when the task is executed simultaneously in multiple processors. In this tutorial, you'll understand the procedure to parallelize any typical logic using python's multiprocessing module.

We will fix that in the long run. Thank you for the kind words. Do buy a CasADi T-shirt ;-) adbuerger commented Sep 1, 2018 Below you can see a modified version of my example given above (cf. this forum post for rationale): import subprocess import multiprocessing as mp import ...
