How can we overcome bus saturation in multi-core systems?

hpcanswers.com: Multi-core systems, in combination with specialized co-processors for hefty tasks, are hailed as the future of high-performance computing. In a bus-based architecture, the environment is an SMP in which all of the memory is accessible by all of the processors in the same amount of time. This setup works well for a few cores, but has tremendous trouble for the dozens of cores promised in the future. The resource contention in an SMP is not a new issue; the solution of yesterday is the same for today: NUMA.
