[slack-digest] [2019-03-13] #performance
2019-03-13 00:01:41 UTC - Matthew Parker: Hi all, I've created a basic function in Python which calculates Pi for a given number of iterations. The top statement in the attached snippet shows how I'm making 4 concurrent invocations of this function with n = 10,000 (number of iterations for Pi). As I understand it, each function is designed to run in its own distinct container, and this holds true for the top statement (4 containers are deployed). When I run the bottom statement, I would expect similar behaviour (8 containers), however, no more than 4 containers are deployed. Is this meant to happen? If so, is there a default setting I can override to achieve "1 container : 1 function"?

2019-03-13 00:08:35 UTC - Carlos Santana: Is the invoker configured and deployed with large memory? The number of concurrent actions on a single invoker is based on memory

2019-03-13 00:09:28 UTC - Carlos Santana: If you deploy with 1 invoker 2GB configured/allocated to functions then for example you can only run 4 containers of 512MB each

2019-03-13 00:21:03 UTC - Matthew Parker: Apologies - I'm still quite new to OpenWhisk, I wasn't aware of this constraint and didn't know the invoker could be configured. Currently, I've just got OpenWhisk running using the 'make run' command from the devtools/docker-compose/ makefile.
