IEEE/ACM International Symposium on Code Generation and Optimization (CGO)
co-located with PPoPP, HPCA and CC
Seoul, South Korea
February 12 - 16, 2022


The International Symposium on Code Generation and Optimization (CGO) is a premier venue to bring together researchers and practitioners working at the interface of hardware and software on a wide range of optimization and code generation techniques and related issues. The conference spans the spectrum from purely static to fully dynamic approaches, and from pure software-based methods to specific architectural features and support for code generation and optimization.


Abstract Submission: August 27, 2021
Paper Submission: September 3, 2021
Author Rebuttal Period: October 18 - October 22, 2021
Paper Notification: November 5, 2021
Artifact Evaluation Deadline: November 12, 2021
Artifact Evaluation Notification: December 10, 2021

Original contributions are solicited on, but not limited to, the following topics:

- Code Generation, Translation, Transformation, and Optimization for performance, energy, virtualization, portability, security, or reliability concerns, and architectural support
- Efficient execution of dynamically typed and higher-level languages
- Optimization and code generation for novel and emerging programming models, hardware platforms, and domain-specific languages
- Dynamic/static, profile-guided, feedback-directed, and machine learning based optimization
- Static, Dynamic, and Hybrid Analysis for performance, energy, memory locality, throughput or latency, security, reliability, or functional debugging
- Program characterization methods
- Efficient profiling and instrumentation techniques; architectural support
- Novel and efficient tools
- Compiler design, practice and experience
- Compiler abstraction and intermediate representations
- Vertical integration of language features, representations, optimizations, and runtime support for parallelism
- Solutions that involve cross-layer (HW/OS/VM/SW) design and integration
- Deployed dynamic/static compiler and runtime systems for general purpose, embedded system and Cloud/HPC platforms
- Parallelism, heterogeneity, and reconfigurable architectures
- Optimizations for heterogeneous or specialized targets, GPUs, SoCs, CGRA
- Compiler support for vectorization, thread extraction, task scheduling, speculation, transaction, memory management, data distribution and synchronization


Last two years CGO had a special category of papers called “Tools and Practical Experience,” which was very successful. CGO this year will have the same category of papers. Such a paper is subject to the same page length guidelines, except that it must give a clear account of its functionality and a summary about the practice experience with realistic case studies, and describe all the supporting artifacts available.

For papers submitted in this category that present a tool it is mandatory to submit an artifact to the Artifact Evaluation process and to be successfully evaluated. These papers will initially be conditionally accepted based on the condition that an artifact is submitted to the Artifact Evaluation process and that this artifact is successfully evaluated. Authors are not required to make their tool publicly available, but we do require that an artifact is submitted and successfully evaluated.

Papers submitted in this category presenting practical experience are encouraged but not required to submit an artifact to the Artifact Evaluation process.

The selection criteria for papers in this category are:

- Originality: Papers should present CGO-related technologies applied to real-world problems with scope or characteristics that set them apart from previous solutions.
- Usability: The presented Tools or compilers should have broad usage or applicability. They are expected to assist in CGO-related research, or could be extended to investigate or demonstrate new technologies. If significant components are not yet implemented, the paper will not be considered.
- Availability: Preferences will be given to tools or compilers that are freely available (at either the source or binary level). Exceptions may be made for industry and commercial tools that cannot be made publicly available for business reasons.
- Documentation: Publicly available tools should be presented on a web-site giving documentation and further information about the tool.
- Test or Benchmark Repository: Tool papers must provide a suite of tests or benchmarks. Papers that make performance claims must provide benchmarks.
- Foundations: Papers should incorporate the principles underpinning Code Generation and Optimization (CGO). However, a thorough discussion of theoretical foundations is not required; a summary of such should suffice.
- Artifact Evaluation: The submitted artifact must be functional and supports the claims made in the paper. Submission of an artifact is mandatory for papers presenting a tool.


The Artifact Evaluation process is run by a separate committee whose task is to assess how the artifacts support the work described in the papers. This process contributes to improving reproducibility in research that should be a great concern to all of us. There is also some evidence that papers with a supporting artifact receive higher citations than papers without (Artifact Evaluation: Is It a Real Incentive? by B. Childers and P. Chrysanthis).

Authors of accepted papers at CGO have the option of submitting their artifacts for evaluation within two weeks of paper acceptance. Authors of tools papers submitted in the category of “Tools and Practical Experience Papers” must submit an artifact. To ease the organization of the AE committee, we kindly ask authors to indicate at the time they submit the paper, whether they are interested in submitting an artifact. Papers that go through the Artifact Evaluation process successfully will receive a seal of approval printed on the papers themselves. Additional information is available on the CGO AE web page. Authors of accepted papers are encouraged, but not required, to make these materials publicly available upon publication of the proceedings, by including them as “source materials” in the ACM Digital Library.

Authors should carefully consider the difference in focus with the co-located conferences when deciding where to submit a paper. CGO will make the proceedings freely available via the ACM DL platform during the period from two weeks before to two weeks after the conference. This option will facilitate easy access to the proceedings by conference attendees, and it will also enable the community at large to experience the excitement of learning about the latest developments being presented in the period surrounding the event itself.
