About

The annual Concurrent Collections (CnC) workshop is a forum for researchers and developers of parallel programs to interact on a variety of issues related to next-generation parallel programming models. The focus is on fostering a community around the CnC programming model. However, we also strongly encourage participation by anyone interested in programming models inspired by dataflow and/or tuple space ideas, as well as current or emerging applications of these models.

Registration

Registration for CnC'14 is mandatory for all participants. To register please visit:

Choose the "CnC-2014 Registration" option. All registrants will need to provide a $30 payment onsite (cash or check accepted).

Registration deadline is Thursday, September 18, 2014.

Phone: (503) 681-2121

The room rate is $109 and is valid for September 17 and 18, 2014.

When making reservations, please refer to "CNC Workshop 2014." The deadline for reservations at the $109 meeting rate is Friday, September 12, 2014.

Participation and Call for Abstracts

The workshop agenda will include CnC tutorials on current and future trends, talks selected from contributed abstracts, and a programming contest. Topics of interest include, but are not limited to: language design and implementation, semantics and theory, application experiences, and teaching CnC.

If you are interested in giving a talk, please submit a short abstract (between 200–500 words in length) to workshop chairs Sanjay Chatterjee and John Feo no later than Friday, August 8, 2014.

Programming Contest

This year, for the first time, we are challenging small teams (as small as one contestant) of CnC developers to compete in a programming contest. If you are interested in competing, please send a team name, list of team member(s), and a problem of choice by Friday, August 8, 2014 to workshop chairs Sanjay Chatterjee and John Feo.

We encourage you to work with the workshop committee to define an appropriate problem. Solutions will be judged on creativity, programming style, solution, and performance. A written report, including source code, is due to both workshop chairs (Chatterjee and Feo) by Friday, September 12, 2014.

We will reserve a session on the first day of the workshop for teams to present their work. While presenting is not required, it is highly encouraged as it provides an opportunity for the committee and audience to better understand your work. A significant prize will be awarded to the winning team at the close of the workshop.

Background on CnC

CnC is a parallel programming model for mainstream programmers that philosophically differs from other approaches. CnC programmers do not specify parallel operations. Instead, they only specify semantic ordering constraints. This provides a separation of concerns between the domain expert and tuning expert, simplifying the domain expert’s job while providing more flexibility to the tuning expert.

Details on CnC and related research can be found at:
http://intel.ly/concurrent-collections
      and
http://habanero.rice.edu/cnc

Prior CnC workshops have served as a forum for users and potential users to discuss experiences with the programming, as well as a range of topics, including developments for the language, applications, usability, performance, semantics, and teaching CnC.
