Busy Java Developer's Guide to ParallelizationPatterns
Getting the most out of your hardware historically was a question of optimizing native code to take advantage of CPU instructions, and setting the right optimization flags on the compiler. Then, when Java came around, it became a matter of simply allowing Hotspot to do its thing. But as the rise of multicore CPUs has made its presence felt in the developer mindspace, so has the need to start writing code in a more parallel/concurrent fashion. Unfortunately, this is an area that most Java developers have historically tried to avoid (like the Plague), so it represents a huge “black hole” for most of them.
In this presentation, we try to lift the cover of the pit over the demons of parallelization, and start exploring some concurrency/parallelization patterns, not with the intent of producing reusable code riffs, but with the intent of giving attendees a good grounding on different designs of parallel processing that apply to more than just Java.
