Think Parallel - Bryce Adelstein Lelbach - ACCU 2024
---

By default, we think sequentially. Parallelism in C++ is often seen as challenging and complex. Tools to be used sparingly and cautiously, and only by experts.

But we must shatter these assumptions, for today, we live in a parallel world. Almost every hardware platform is parallel, from the smallest embedded devices to the largest supercomputers.

We must change our mindset. Anyone who writes C++ code has to think in parallel. Parallelism must become our default.

In this example-driven talk, we will journey into the world of parallelism. We'll look at four algorithms and data structures in depth, comparing and contrasting different implementation strategies and exploring how they will perform both sequentially and in parallel.

During this voyage, we'll uncover and discuss some foundational principles of parallelism, such as latency hiding, localizing communication, and efficiency vs performance tradeoffs. By the time we're done, you'll be thinking in parallel.

The ACCU Conference is the annual conference of the ACCU membership, but is open to any and all who wish to attend. The tagline for the ACCU is 'Professionalism in Programming', which captures the whole spectrum of programming languages, tools, techniques and processes involved in advancing our craft. While there remains a core of C and C++ - with many members participating in respective ISO standards bodies - the conference, like the organisation, embraces other language ecosystems and you should expect to see sessions on C#, D, F#, Go, Javascript, Haskell, Java, Kotlin, Lisp, Python, Ruby, Rust, Swift and more.The ACCU Conference is a conference by programmers for programmers about programming.
Discounted rates for members.
