CGO 2026: Call for Papers

The International Symposium on Code Generation and Optimization (CGO’26) will be held in Sydney, Australia, in the early spring of 2026. CGO is the 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.

CGO will be held in conjunction with CC, HPCA, and PPoPP.

Submission Rounds

CGO uses two submission rounds per year. Papers submitted to the first round can either be directly accepted, rejected, or invited to submit a revised version to the second round. Papers rejected in the first round may not be submitted to the second round.

First Submission Round

• Paper Submission Deadline: 29 May 2025
• Author Rebuttal Period: 8–10 July 2025
• Paper Notification: 21 July 2025

Second Submission Round

• Paper Submission Deadline: 11 September 2025
• Author Rebuttal Period: 21–23 October 2025
• Paper Notification: 3 November 2025

Topics

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 emerging programming models, platforms, domain-specific languages
• Dynamic, static, profile-guided and feedback-directed optimization
• Machine-learning-based code generation, analysis, transformation and optimization
• Static, dynamic, and hybrid analysis for performance, energy, memory locality, throughput or latency, security, reliability, or functional debugging
• Program characterization methods
• Profiling and instrumentation techniques and architectural support for them
• 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 and quantum computers
• Compiler support for vectorization, thread extraction, task scheduling, speculation, transaction, memory management, data distribution and synchronization

Paper Types

Papers submitted to CGO can be standard research papers, tools papers, or practical experience papers.

• Format: IEEE conference format (use the conference mode).
• Page Limit: Up to 10 pages, excluding references. Supplementary materials may be included as an Appendix with no page limit, but reviewers are not required to read it.
• Font Size: 10pt or larger.
• Paper Size: Letter-size (8.5″x11″).
• Submission Format: PDF.
• Printing: Formatted for black-and-white printers, with readable graph labels.
• Page Numbering: Required.
• Line Numbers: Recommended (e.g., using the lineno package in LaTeX).
• Language: English.

Tools Papers

• Must describe the tool’s functionality, the problem it solves, and provide an evaluation.
• Novelty can be in the problem solved or the method used.
• Authors should prepend their title with Tool:.
• Successful artifact evaluation is mandatory.

Practical Experience Papers

• Should summarize practical experience with realistic case studies, highlighting novelty.
• Authors should prepend their title with Practical:.
• Artifact submission is encouraged but not required.

Double-Blind Reviewing

• Papers are to be submitted for double-blind review.
• Author names and hints of identity must be removed from the submitted paper.
• When extending prior work, reference and discuss it in the third person.

Artifact Evaluation

• Authors of accepted papers have the option to submit artifacts for evaluation.
• Papers with successfully evaluated artifacts receive a seal of approval.
• Authors are encouraged to indicate interest in submitting an artifact at the time of submission.

Conflicts of Interest

Authors must register all conflicts on the paper submission site to ensure appropriate reviewer assignment.
