Revisiting Amdahl's Law
An anonymous reader writes "A German computer scientist is taking a fresh look at the 46-year old Amdahl's law, which took a first look at limitations in parallel computing with respect to serial computing. The fresh look considers software development models as a way to overcome parallel computing limitations. 'DEEP keeps the code parts of a simulation that can only be parallelized up to a concurrency of p = L on a Cluster Computer equipped with fast general purpose processors. The highly parallelizable parts of the simulation are run on a massively parallel Booster-system with a concurrency of p = H, H >> L. The booster is equipped with many-core Xeon Phi processors and connected by a 3D-torus network of sub-microsecond latency based on EXTOLL technology. The DEEP system software allows to dynamically distribute the tasks to the most appropriate parts of the hardware in order to achieve highest computational efficiency.' Amdahl's law has been revisited many times, most notably by John Gustafson." at Slashdot. [...]
