We examine the world of infrastructure (bits, cores, and fabrics) through the lens of data. The talk begins with a survey of data sources, data varieties, and their growth trends. We review the lifecycle of data in order to understand the processes by which data is turned into insightful information. The body of the talk takes a data-centric view of the world and derives a memory-centric computer architecture, in which the primacy of data is reflected in the engineering of infrastructure. We will see that bits, cores and fabrics line up very differently in a memory-centric architecture than in traditional architectures, and even basic operating systems concepts such as virtual memory have a new design.
The talk concludes with a survey of long-term workload and device architecture trends, especially machine learning and memristive devices, and how that aligns with a move to data centricity.
