** 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. iWAPT is collocated with the 40th IEEE International Parallel & Distributed Processing Symposium (IPDPS) in New Orleans, LA, USA.


** Topics of Interest
We are particularly interested in autotuning and its relationship to the following topic areas, among others. This year we added new topics at the intersection of HPC, AI, Quantum and Energy consumption for auto-tuning:

- 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
