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 2022 (SCA22), 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 and Singapore, the SCA22 will be held from 01 to 03 March 2022 as a hybrid conference at Suntec Singapore Convention & Exhibition Centre. |

The impact of the next-generation arithmetic is similar to that of a turn of Moore’s law – doubling computing capability but without having to shrink transistors. Current floating-point numbers (“floats”) were standardised in the 1980s when transistors were millions of times more expensive than they are now; floats make compromises that are overdue for update. The ability to train neural networks with fewer bits (≤16 bits) provides an enormous performance boost for artificial intelligence (AI), presently the most important computing focus and challenge. Novel arithmetic is a game changer for the computing industry. The game in High Performance Computing (HPC) presently is to achieve exascale computing, which most practitioners implicitly assume means a billion double-precision floating-point operations per second while meeting the critical power envelope challenge of staying under 20 MW. The ability of the new generation arithmetic to use fewer bits for the same/higher computation accuracy will facilitate meeting both the performance and power challenges of exascale computing.
Unum arithmetic, in particular the newest type of unums (posits), is an example of a disruptive new format. Posits were designed at the request of the RISC-V committee. They have higher accuracy and a larger dynamic range using the same number of bits, or what is perhaps more disruptive, sufficient accuracy using fewer bits, thereby saving storage, bandwidth, energy and power. Posits produce bitwise-identical results across diverse computer systems; current floats cannot even guarantee identical results on successive program runs. To a large extent, posits can serve as drop-in replacements for floats of the same precision; however, the advantages of increasing speed while lowering chip area, power/energy consumption, storage, and bandwidth demands come from using posits to reduce precision requirements without sacrificing accuracy.
Changing arithmetic however affects the entire hardware-software stack from chip design to the application. The Conference on Next Generation Arithmetic provides an excellent opportunity for computer arithmetic enthusiasts to gather, interact and exchange ideas on not only what the next generation arithmetic should be, but also the news and updates on the latest developments of breakthroughs with next generation data formats and their corresponding hardware, tools, applications, services, etc.. |

Proceedings
The conference proceedings will be published in Springer Nature’s Lecture Notes in Computer Science (LNCS).
All submissions for CoNGA must follow Springer’s LNCS format* without changing default margins, fonts, etc. Authors should use the proceedings templates, either for LaTeX or for Word, for the preparation of their papers. The total page limit is 18 pages excluding references. 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 18 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 be available to present the paper at SCA22 (1-3 March 2022, Singapore) in person or virtually.
