You already know that achieving a linear speedup as the number of cores increases in real life parallelized applications is indeed very difficult. However, sometimes, the multicore scalability of certain algorithms for existing multicore systems could be worse than expected. The overhead and the bugs introduced by concurrency could bring really unexpected scalability problems when the number of cores increases. Intel can help you with a free service in the cloud.
