You'd like to improve the performance of your application with regard to memory management, and you believe this can be accomplished by writing a custom allocator. But where do you start? Modern C++ brings many improvements to the standard allocator model, but with those improvements come several issues that must be addressed when designing a new allocator.
This talk will provide guidance on how to write custom allocators for the C++14/C++17 standard containers. It will cover the requirements specified by the standard, and will describe the facilities provided by the standard to support the new allocator model and allocator-aware containers. We'll look at the issues of allocator identity and propagation, and examine their implications for standard library users, standard library implementers, and custom allocator implementers. We'll see how a container uses its allocator, including when and how a container's allocator instance propagates. This will give us the necessary background to describe allocators that implement unusual semantics, such as a stateful allocator type whose instances compare non-equal. Finally, the talk will provide some guidelines for how to specify a custom allocator's public interface based on the semantics it provides.

Bob Steagall: KEWB Computing, CppCon 2017 Poster Chair
I've been working in C++ for the last 25 years. The majority of my career has been spent in medical imaging, where I led teams building applications for functional MRI and CT-based cardiac visualization. After a brief journey through the world of DNS and analytics, I'm now working in the area of stream processing.
