PARALLEL ARCHITECTURES
As we’ve discussed, computing is splitting along two paths: low-power systems, forming the Internet of Things; and high-power computing centers, forming the cloud. In previous chapters, we’ve looked at the low-power IoT side of the split: embedded and smart systems. This chapter will look at the high-power, high-performance systems found in the cloud. Specifically, we’ll look at parallelism, the backbone of cloud computing.
The rise of parallelism is related to Moore’s two laws. While Moore’s law for density says we can still put more and more transistors on chips, Moore’s law for clock speed is now over, meaning we can’t ...
