The latest newsletter from IEEE Computer Society encourages us to bring multi-core programming into the mainstream. http://www.computer.org/portal/web/buildyourcareer/hs12?utm_source=bronto&utm_medium=email&utm_term=Tackling+Parallel+Programming&utm_content=davidkrethallen%40gmail.com&utm_campaign=BYC+8+August+2011
As I pointed out in a recent post, with Microsoft’s Task Parallel Library, this is much easier. Though you still need to learn to think in terms of concurrency and the issues that arise from multiple threads accessing the same state.
If you have not played with these types of tools on your platform of choice, I encourage you to look for opportunities where performance gains are needed and give it a try.
