Shared data across python-actions

[Tom Varga]

I'm trying to summarize total cpu runtimes across all python-actions, especially when they're being run in parallel.

I was hoping to have each python-action update a variable in the Globals class by adding its runtime to the running total.

This seems to work fine if I set the 'par_type' option to 'thread'

Perhaps not unexpectedly, this doesn't work if it's set to 'process' (multiprocessing).

After some googling, it appears that I might be able to use the multiprocessing.share_memory module that's become available in 3.8.

However, before I go down that path, I'm wondering if anybody has a better suggestion?

Might it be possible to return some extra information from the python-action and collect it somehow at the top-level?

Thanks,

-Tom
