An anonymous reader writes: Intel’s Aater Suleman writes about why parallel programming is difficult. He uses real life code examples to show why finding parallelism is difficult and specifying it is a daunting task. I was unaware of the fact that a major challenge in multi-threaded programming lies in optimizing parallel programs, not just getting them to run. Aater Suleman presented a full case study (http://www.futurechips.org/tips-for-power-coders/writing-optimizing-parallel-programs-complete.html) of how code is parallelized and the kind of issues parallel programmers must tackle to get high performance. His analysis is insightful and the case study is very enlightening if you are unfamiliar with parallel code debugging. His article has already been featured on sites like insidehpc.com and multicore.info .
