Multiple for loops

[richardrl]

I noticed if I have multiple for loops, or nested for loops, in the @synchronized function, the @Concurrent function does not sync properly

[richardrl]

Perhaps this is working as intended, just read the docs about synchronized requiring simple functions

[alex-sherman]

Multiple for loops should work correctly, do you have a small example where it doesn't?

[richardrl]

@alex-sherman I lost that example, but here's another example of slightly complicated logic that completely loses speedup vs the same code with the speed up:

Speed up: https://gist.github.com/richardrl/32c37f4efcec62d526b23f2b640a36f9

No speed up: https://gist.github.com/richardrl/a88cbde63634c86a4291e4b63e28d75c

If you diff the files you will see the only difference is the second file has an if statement before the main parallelizable part.

[alex-sherman]

Can you provide a more minimal example? I can't run this script, and the diff seems to include a sleep statement or perhaps even an infinite loop? I can't tell.
