THIS TUTORIAL HAS REQUIREMENTS AND INSTRUCTIONS LISTED BELOW
Erlang’s basic features are a perfect match for massively concurrent, distributed cloud environments. Being rooted in an actor model with no shared memory, the complexity of multi-core programming is hidden from the developers, allowing them to focus on the program. This tutorial will introduce Erlang and its actor model, explaining how it is positioning itself to win the multi-core challenge.
Basic & Sequential Erlang
This section deals with Erlang data types and pattern matching. Functions, and modules are discussed. It continues by introducing recursion, with a special emphasis on different recursive patterns, including tail recursion.
This section describes the creation of processes and their life span. It looks at sending and receiving messages, selective reception, and passing data in the messages. It continues with the various uses of time outs and registering processes, and terminates by showing the generic process code structure. We conclude this section by introducing the simple but powerful error handling mechanisms in processes. It looks at process links, exit signals and their propagation semantics.
This section guides the users through examples and scalability issues when writing programs you expect to double in speed when doubling your cores. It covers tools and programming techniques you can use to detect and avoid bottlenecks.
TUTORIAL REQUIREMENTS AND INSTRUCTIONS FOR ATTENDEES
In order to get the most out of this tutorial, you must have a good grasp of other programming languages. Having dabbled with http://tryerlang.org is not necessary, but will help. This is a hands on tutorial.
* Before arriving, download and install Erlang and get the Erlang mode for your favorite editor working. Erlang (source or binaries) can be downloaded at https://www.erlang-solutions.com/downloads/download-erlang-otp

Francesco Cesarini is the founder and technical director of Erlang Solutions. With offices in seven countries on three continents, Erlang Solutions has become the go-to partner for scalable, highly available end-to-end solutions, running conferences, and providing support, consulting, training, certification, and systems development. As technical director, Francesco leads the development and consulting teams and is responsible for the product and research strategies of the company.
Francesco has used Erlang on a daily basis since 1995, when he started his career as an intern at Ericsson’s computer science laboratory, the birthplace of Erlang. He moved on to Ericsson’s Erlang training and consulting arm, where he worked on the R1 release of OTP, applying it to turnkey solutions and flagship telecom applications. In 1999, soon after Erlang was released as open source, Francesco founded what has today become Erlang Solutions. He is the coauthor of Erlang Programming (published by O’Reilly), has lectured at the IT University of Gothenburg for over a decade, and since 2010, has taught the concurrency-oriented programming course at Oxford University. You can find him rambling on twitter using the handle @FrancescoC.
