Parallelising your code. Do you do it?   [Edit]

Survey period: 5 Jul 2010 to 12 Jul 2010

Our CPUs aren't getting as fast as fast as they used to, and we're now well and truly in a multi-core world. What do you do to take advantage of this? (Suggested by El Corazon)

I don't know how this is with other platforms, but on Windows the most common reason for parallelism is not performance, but keeping the UI active (not sure if this counts as "strict" parallelism).

Also, when writing libraries to be consumed by others, you often have to design for parallelism, whether it gets used or not.

And yes, it's a pain. Roll eyes | :rolleyes:
