The F# Asynchronous Programming Model, PADL 2011
[ The draft was updated on 22/10/10 and 8/11/10 ] The F# asynchronous programming model dates to 2007, and was published in product documentation and Expert F#. However, until now we haven't had a submitted, succinct conference-style description of the core idea of the model: language integrated asynchronous programming. As a result Tomas Petricek, Dmitry Lomov … Continue reading The F# Asynchronous Programming Model, PADL 2011
Async and Parallel Design Patterns in F#: Agents
In part 3 of this series, we explore lightweight, reactive agents in F# and look at some typical design patterns associated with these agents, including isolated internal state. Part 1 describes how F# is a parallel and reactive language with support for light-weight reactions, and gives patterns for parallel CPU asyncs and parallel I/O asyncs. Part 2 described a pattern for … Continue reading Async and Parallel Design Patterns in F#: Agents

Some of the samples are … Continue reading Async and Parallel Design Patterns in F#: Reporting Progress with Events (plus Twitter Sample)
Async and Parallel Design Patterns in F#: Parallelizing CPU and I/O Computations
F# is both a parallel and a reactive language. By this we mean that running F# programs can have both multiple active evaluations (e.g. .NET threads actively computing F# results), and multiple pending reactions (e.g. callbacks and agents waiting to react to events and messages). One simple way to write parallel and reactive … Continue reading Async and Parallel Design Patterns in F#: Parallelizing CPU and I/O Computations
