Call for Papers

Paper submission by 30 November 2022 (Extended)

Notification of acceptance of papers by 19 December 2022 (Extended)

Camera-ready papers by 16 January 2022 (Extended)

CoNGA'23 invites original contributions on topics related to next generation arithmetic, specifically universal number (unum) and posit arithmetic, including, but not limited to:

  • Posit & Valid Arithmetic
  • Artificial Intelligence Data Formats
  • Energy Efficient Arithmetic
  • Right Sizing Precision

Authors are invited to submit manuscripts of original, unpublished research and recent development in next generation arithmetic (NGA).
The submitted manuscripts can be up to 16 pages, written in English and formatted according to the Springer’s LNCS format's templates without changing default margins, fonts, etc. .
Submissions will be accepted electronically via EasyChair.
Accepted manuscripts will be published as a part of Lecture Notes in Computer Science (LNCS) revised post-proceedings volume. CoNGA'22 volume can be found here.

Authors should use the proceedings templates, either for LaTeX or for Word, for the preparation of their papers. Supplementary materials that facilitate verification of the results, e.g., source code, proof details, etc., may be appended without a page limit or uploaded as separate files, but reviewers are neither required to read them nor will they be printed in the proceedings. Hence submissions must be complete, intelligible and self-contained within the 16 pages limit. Papers should have page numbers to facilitate their review. In LaTeX, this can be achieved for instance using\pagestyle{plain}. Each submission must be a single PDF file. Springer encourages authors to include their ORCIDs in their papers. Springer also offers a feature for the inclusion of embedded videos in proceedings papers.

In addition, the corresponding author of each paper, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form. The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to Springer, changes relating to the authorship of the papers cannot be made. Papers should present original research and should provide sufficient background material to make them accessible to the broader community. It should not be submitted in parallel to any other conference or journal. All manuscripts will be reviewed and judged on correctness, originality, technical strength, and significance, quality of presentation, and interest and relevance to the conference. At least one author of an accepted paper should preferably be available to present the paper at CoNGA'23 (27–28 February 2023, Singapore) in person.

About CoNGA'23

Conference on Next Generation Arithmetic (CoNGA) is the leading conference on emerging technologies for computer arithmetic. The demands of both AI and HPC have led the community to realize that something better than traditional floating-point arithmetic is needed to reach the speed, accuracy, and energy-efficiency that are needed for today's most challenging workloads. In particular, posit arithmetic is achieving rapid adoption as a non-proprietary format, but CoNGA welcomes papers about any arithmetic format that breaks from the past and shows merit and promise.

CoNGA will be held in conjunction with Supercomputing Asia 2023 (SCA23), an annual international conference that encompasses an umbrella of notable supercomputing events with the key objective of promoting a vibrant and relevant HPC ecosystem in Asia. Co-organised by HPC centres from Australia, Japan, Thailand and Singapore, the SCA23 will be held from 27 February to 2 March 2023 in Singapore. In conjunction with SCA23, the HPC Asia 2023 conference will also be co-located with SCA23 in Singapore for the first time.
