HIPERFIT Seminar Talk

Title: Chapel: Parallel Programmability from Desktops to Supercomputers.

Presenter: Brad Chamberlain, Principal Engineer, Cray Inc.

Time: Thursday, February 4, 2016, 15:15-16:15

Place: DIKU Building, Small Auditorium, UP1, Universitetsparken 1, University of Copenhagen.


Chapel (http://chapel.cray.com) is an emerging open-source language whose goal is to vastly improve the programmability of parallel systems while also enhancing generality and portability compared to conventional techniques. Chapel is seeing growing levels of interest not only among HPC users, but also in the data analytic, academic, and mainstream programming communities. Chapel’s design and implementation are portable and open-source, supporting a wide variety of compute platforms, from desktops (Mac, Linux, *nix) to commodity clusters, the cloud, and large-scale systems developed by Cray and other vendors.

In this talk, I’ll start by providing motivation and context for Chapel before giving an overview of its unique feature set. I’ll also describe the status and organization of the Chapel project itself, highlighting opportunities for collaboration.



Brad Chamberlain is a Principal Engineer at Cray Inc. where he works on parallel programming models, focusing primarily on the design and implementation of the Chapel language in his role as technical lead for that project. Brad received his Ph.D. in Computer Science & Engineering from the University of Washington in 2001 where his work focused on the design and implementation of the ZPL parallel array language. His thesis explored the concept of ‘regions’ — a first-class index set supporting global-view data parallelism and a syntactic performance model. Brad remains associated with the University of Washington as an affiliate professor. He received his Bachelor’s degree in Computer Science with honors from Stanford University in 1992.

Hosts: Martin Elsman, DIKU and Brian Vinter, NBI.

Everyone is welcome! Beers, soda, and snacks will be served after the talk.
