C++Now Announces Opening Keynote by Lisa Lippincott

C++Now 2018 will be held in Aspen, May 6–11, 2018.

C++Now 2018 Opening Keynote is Lisa Lippincott

From the announcement:

Lisa approaches languages from a mathematical point of view and thinks deeply on the meaning of programming. In this presentation [The Shape of a Program], she will encourage us to apply topology, the fundamental mathematics of space, as a way of looking at a program.

We expect C++Now to sell out again. Register immediately so you won’t miss out.

Chandler Carruth: Optimizing the Emergent Structures of C++

We are confronted today with the increasing complexity of our C++ software systems. To manage this complexity and build larger applications and systems, C++ strives to form emergent structures (often found in nature, such as snowflakes' symmetrical structures), where simple patterns combine to form a remarkably complex and powerful system. These structures provide both a means to limit the complexity of each component and the essential economies of scale we rely on when developing software.

From handheld devices to warehouse-sized data centers, motivated by smaller devices and increased concerns over power consumption, we are relying upon C++ to deliver these complex systems with unmatched efficiency. Our optimizing compilers today are more important than ever before and are utterly opaque to most practicing programmers. Compounding matters, the very emergent structures which allow C++ systems to scale for humans often provide unique and unsolved challenges to optimization.

In this talk, I will start with a brief overview of how modern optimizing compilers work with C++ code at a very high level. I will then walk through the specific structures and patterns of C++ code, which are at the core of forming emergent structures out of simple, elegant elements. I will also address how these interactions can be effectively modeled and analyzed by a compiler to produce efficient final programs. All of this will be illustrated by a collection of real world case studies, which are broadly applicable and show up throughout modern C++ code bases. My goal is to give a framework for understanding these interactions both in the C++ code and the optimizing compiler, so that programmers are aware of the implications posed by these patterns. Finally, I will introduce a set of principles and techniques for designing and implementing C++ programs and libraries to specifically clear the way for modern optimizers while retaining the simplicity of each component and the power of the combined whole.

Stanley Lippman: yet another paradigm shift (yaps) - a Meta4 model of concurrency

We'll discuss language life cycles, particularly as they apply to C++, from a peek at some of the very early ideas and technology behind C++ to a proposal for the next step: yet another paradigm shift, not a evolution or revolution but simply a synchronizing of meta4layers — using fertilization of the multi-cell organism as an isomorph.
