The Multicore Dilemma

Anuradha Menon - The Future of Things

Researchers at Sandia National Laboratories uncovered performance issues during simulations of multi processors; they found that when the number of processor cores on an individual chip is increased, it impairs the performance of complex applications. In a world where the achievement of the supercomputer is paramount, the team at Sandia simulated key algorithms for deriving information from large data sets only to find a significant decrease in speed when the system exceeded eight multicores.
