Conference Overview

The goal of the Eighteenth International Workshop on Automatic Performance Tuning (iWAPT2026)
is to bring together researchers who are investigating automated techniques for constructing
and/or adapting algorithms and software for high-performance on modern complex machine
architectures.

Topics of Interest

We are particularly interested in autotuning and its relationship to the following topic areas, among others:

Use of Generative AI for autotuning
Autotuning with quantum computing technology
Machine-adaptive algorithms
Automatic program generation
Performance analysis and modeling
Adaptive numerical algorithms and libraries
Multi- and manycore systems, heterogeneous architectures challenges
Compilation strategies(e.g. iterative and empirical compilers)
Programming models
Runtime systems
Empirical search heuristics
Power- and/or energy-aware computing
Hyper-parameter tuning for machine learning
