Array-oriented programming unites two uncommon properties. As an abstraction, it directly mirrors high-level mathematical abstractions commonly used in many fields from natural sciences over engineering to financial modeling. As a language feature, it exposes regular control flow, exhibits structured data dependencies, and lends itself to many types of program analysis. Furthermore, many modern computer architectures, particularly highly parallel architectures such as GPUs and FPGAs, lend themselves to efficiently executing array operations.

The ARRAY series of workshops explores:

• formal semantics and design issues of array-oriented languages and libraries;

• productivity and performance in compute-intensive application areas of array programming;

• systematic notation for array programming, including axis- and index-based approaches;

• intermediate languages, virtual machines, and program-transformation techniques for array programs;

• representation of and automated reasoning about mathematical structure, such as static and dynamic sparsity, low-rank patterns, and hierarchies of these, with connections to applications such as graph processing, HPC, tensor computation and deep learning;

• interfaces between array- and non-array code, including approaches for embedding array programs in general-purpose programming languages; and

• efficient mapping of array programs, through compilers, libraries, and code generators, onto execution platforms, targeting multi-cores, SIMD devices, GPUs, distributed systems, and FPGA hardware, by fully automatic and user-assisted means.

Array programming is at home in many communities, including language design, library development, optimization, scientific computing, and across many existing language communities. ARRAY is intended as a forum where these communities can exchange ideas on the construction of computational tools for manipulating arrays.

Call for Papers

Array programming is at home in many communities, including language design, library development, optimization, scientific computing, and across many existing language communities. The ARRAY Workshop series is intended to bring together researchers from many different communities, including language designers, library developers, compiler researchers, and practitioners, where these communities can exchange ideas on the construction of computational tools for manipulating arrays.

The ARRAY series of workshops explores:

  • formal semantics and design issues of array-oriented languages and libraries;

  • productivity and performance in compute-intensive application areas of array programming;

  • systematic notation for array programming, including axis- and index-based approaches;

  • intermediate languages, virtual machines, and program-transformation techniques for array programs;

  • representation of and automated reasoning about mathematical structure, such as static and dynamic sparsity, low-rank patterns, and hierarchies of these, with connections to applications such as graph processing, HPC, tensor computation and deep learning;

  • interfaces between array- and non-array code, including approaches for embedding array programs in general-purpose programming languages; and

  • efficient mapping of array programs, through compilers, libraries, and code generators, onto execution platforms, targeting multi-cores, SIMD devices, GPUs, distributed systems, and FPGA hardware, by fully automatic and user-assisted means.

Submissions

Submissions are welcome in two categories: full papers and extended abstracts. All submissions should be formatted in conformance with the ACM SIGPLAN proceedings style. Accepted submissions in either category will be presented at the workshop.

All submissions must be in PDF format, printable in black and white on US Letter sized paper. Papers must adhere to the standard SIGPLAN conference format: two columns, ten-point font.

Full papers may be up to 12 pages, on any topic related to the focus of the workshop. They will be thoroughly reviewed according to the usual criteria of relevance, soundness, novelty, and significance; accepted submissions will be published in the ACM Digital Library.

Extended abstracts may be up to 2 pages; they may describe work in progress, tool demonstrations, and summaries of work published in full elsewhere. The focus of the extended abstract should be to explain why the proposed presentation will be of interest to the ARRAY audience. Submissions will be lightly reviewed only for relevance to the workshop, and will not published in the DL.

Important Dates

Paper Submission: 2 Apr 2021

Author notification: 23 Apr 2021

Camera Ready: 5 May 2021

AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work. (For those rare conferences whose proceedings are published in the ACM Digital Library after the conference is over, the official publication date remains the first day of the conference.)
