Focus and Description

Array-oriented programming is a powerful abstraction for compactly implementing numerically intensive algorithms. Many modern languages now provide some support for collective array operations, which are used by an increasing number of programmers (and non-programmers) for data analysis and scientific computing.

This workshop is intended to bring together researchers from many different communities, including language designers, library developers and compiler researchers, who are working on numeric languages such as R and MATLAB, general-purpose dynamic languages such as Python and JavaScript, and statically typed languages such as Haskell, Scala, and C#.

The aim of this workshop is to foster the cross-pollination of concepts across projects and research communities and to explore new directions, such as:

• Expanding the scope of array programming to encompass a wider range of data types and computations.
• Transparently utilizing parallel hardware (multi-core, SIMD, GPU, FPGA) by leveraging the implicitly parallel semantics of array operations.
• Simplifying the embedding of array constructs within existing languages which weren't designed for numerical computing.
• Connections between array abstractions and other models such as dataflow programming, stream programming, and data parallelism.
• High-level compilation and optimization techniques for array-oriented programs.
• Compilers, virtual machines and frameworks for array-oriented programming languages.

Submissions

Submissions should be four to six-page papers in ACM SIGPLAN proceedings style. Submissions may be one of the following:

• research paper on any topic related to the focus of the workshop
• tool description reporting on a tool relevant to the topic of the workshop. In the case of a tool description the workshop presentation should include a demo of the tool, and the submission should include a short appendix summarizing the tool demo. This appendix is for the information of the PC only, and will not be part of the published paper, nor does it count in the six page limit.

Papers can now be submitted using EasyChair

Publication

Accepted papers will be published in the ACM Digital Library.

Schedule

The workshop will span both Thursday afternoon and all of Friday. Schedule details will be available in the near future.
