Why do you write C++ code? There is a good chance it is in part because of concerns about the performance of your software. Whether they stem from needing to run on every smaller mobile devices, squeezing the last few effects into video game, or because every watt of power in your data center costs too much, C++ programmers throughout the industry have an insatiable desire for writing high performance code.
Unfortunately, even with C++, this can be really challenging. Over the past twenty years processors, memory, software libraries, and even compilers have radically changed what makes C++ code fast. Even measuring the performance of your code can be a daunting task. This talk will dig into how modern processors work, what makes them fast, and how to exploit them effectively with modern C++ code. It will teach you how modern C++ optimizers see your code today, and how that is likely to change in the coming years. It will teach you how to reason better about the performance of your code, and how to write your code so that it performs better. You will even learn some tricks about how to measure the performance of your code.

Chandler Carruth leads the Clang team at Google, building better diagnostics, tools, and more. Previously, he worked on several pieces of Google’s distributed build system. He makes guest appearances helping to maintain a few core C++ libraries across Google’s codebase, and is active in the LLVM and Clang open source communities. He received his M.S. and B.S. in Computer Science from Wake Forest University, but disavows all knowledge of the contents of his Master’s thesis. He is regularly found drinking Cherry Coke Zero in the daytime and pontificating over a single malt scotch in the evening.

Ask a non-C++ developer what they think of C++ and they'll give the language plenty of compliments: powerful, fast, flexible, and "the language for smart people". But along with that you are likely to hear ugly, complicated, hard ...

Example-driven talk on how to design and write lock-free algorithms and data structures using C++ atomic -- something that can look deceptively simple, but contains very deep topics. (Important note: This is not the same as my "atomic ...

Reasonably-written C++ code will be naturally fast. This is to C++'s excellent low-penalty abstractions and a memory model close to the machine.
However, a large category of applications have no boundaries on desired speed, meaning there's no point of ...

A primary use case for C++ is low latency, low overhead, high performance code. But C++ does not give you these things for free, it gives you the tools to control these things and achieve them where needed. How do you realize this potential of the language? How do you ...

The standard library containers are often both misused and underused. Instead of creating new containers, applications are often structured with incidental data structures composed of objects referencing other object. This talk looks at some of the ways the standard containers can be better utilized and how creating (or using non-standard ...

C++98 had template type deduction, and it worked so intuitively, there was little need to understand what took place under the covers. C++11 extends type deduction to include universal references, applies it to auto variables and lambda expressions, ...
