The GMT offsets shown reflect the offsets at the moment of the conference.

Time Band

By setting a time band, the program will dim events that are outside this time window. This is useful for (virtual) conferences with a continuous program (with repeated sessions).
The time band will also limit the events that are included in the personal iCalendar subscription service.

Abstract

With the availability of multicore variants of the recent OCaml versions (4.10 and 4.11) that maintain backwards compatibility with the existing OCaml C-API, there has been increasing interest in the wider OCaml community for parallelising existing OCaml code. We propose a presentation which will take the attendees through the following steps aimed at developing parallel programs with Multicore OCaml:

Installing the latest Multicore OCaml compiler
Brief overview of the low-level API for parallel programming
A tour of domainslib – a high-level parallel programming library for Multicore OCaml
Common pitfalls when parallelising
Tools for diagnosing Multicore OCaml performance issues
