This blog post is a brief history lesson about the Erlang compiler for the BEAM machine. To provide some context, there will first be a quick look at the abstract machines for Erlang.
The BEAM interpreter in erts has been completely re-written in OTP 21. Most of the instructions have remained the same, but the perl scripts used to generate the C code have a new implementation. This blog post will look at some of the optimizations that were possible because of those changes.
This blog post wraps up the exploration of Core Erlang started in the previous two blog posts. The remaining default Core Erlang passes are described, followed by a look at how Core Erlang is represented internally in the compiler.
This blog post continues the exploration of Core Erlang by
looking at some optimizations done by the
compiler pass. The Core Erlang language was introduced in
the previous blog post.
This blog post is the first about the Core Erlang format. In this blog post, we introduce the Core Erlang format through examples that compare Erlang code to the corresponding Core Erlang code.
OTP-21 Release Candidate 1 has just been released. I thought that I would go through the changes that I am the most excited about. Most likely this will mostly mean features in erts and the core libraries as those are the changes that I am the most familiar with.
The memory instrumentation module was rewritten for Erlang/OTP 21 to make it easier to use. In this post I’ll describe the rationale behind the new features and how to make use of them.
In this blog post, we will explore the compiler passes that make up the compiler’s front end.
This is the first of a series of blog posts about the compiler. There
will be blog posts about how the compiler works now, how it might work
in the future, and some historical notes to explain why some things
are what they are. In this blog post I will talk about one of the most
useful options for exploring the compiler, namely the
Erlang/OTP 21 will introduce a completely new IO polling implementation. This new implementation comes with a new set of tuneable parameters that can be used to get the most out of your system. This blog post describes the parameters and attempts to describe what they should be used for.
