Evolution of processor architectures: growing complexity of CPUs and its impact on the software landscape

31/3-004 - IT Amphitheatre (CERN)

Description

During the last decade there was a major change in the processing hardware landscape. While Moore's law still drives the increase of the transistor count, the processing units get new architectural features and increase number of cores. This in turn forces a programming paradigm change and encourages new strategies in efficient programming.
In this lectures we will analyze how the CPUs evolved over time and what impact does this evolution has on software. The simplest approaches to leverage parallelism at different level will be shown. We will look at the bottlenecks of the processing hardware and trends that might shape the next decade of computing.

This lecture will provide the participants with the foundations of the computing hardware. It will set of from the early theoretical abstraction. Then, a model of a simple processor will be discussed. Subsequently, we will focus on various architectural features present in the modern hardware and will try to understand their roles and delivered gains. Targeted audience: This lecture targets...

9. Multi-core processors and multithreading

This lecture will analyze trends in the evolution of the hardware architectures, as well as software approaches to harness parallelism. It will justify the need for multithreaded software and will explain why there are no major gains in single thread performance anymore. Targeted audience: The lecture targets participants willing to follow developments in the computing hardware and to...
