ExHET 2025
The 4th International Workshop on Extreme Heterogeneity Solutions
to be held in conjunction with
PPoPP 2025
02 March, 2025
Las Vegas, NV, USA
Introduction
While computing technologies have remained relatively stable for nearly two decades, new architectural features, such as specialized hardware, heterogeneous cores, deep memory hierarchies, and near-memory processing, have emerged as possible solutions to address the concerns of energy efficiency, manufacturability, and cost. However, we expect this ‘golden age’ of architectural change to lead to extreme heterogeneity and will have a major impact on software systems and applications. In this upcoming exascale and extreme heterogeneity era, it will be critical to explore new software approaches that will enable us to effectively exploit this diverse hardware to advance science, the next-generation systems with heterogeneous elements will need to accommodate complex workflows. This is mainly due to the many forms of heterogeneous accelerators (no longer just GPU accelerators) in this heterogeneous era, and the need to map different parts of an application onto elements most appropriate for that application component. In addition, this year we are acknowledging a now clear trend by explicitly encouraging contributions involving the use of trained AI methods -- for example, the use of GPT for code generation.
Objectives, scope and topics of the workshop
This workshop aims to provide a forum to discuss new and emerging solutions to address these important challenges from the upcoming extreme heterogeneity era. Papers are being sought on many aspects of heterogeneous computing including (but not limited to):
- Heterogeneous Programming Environments and Runtime Systems
- Programming models and systems
- Parallel resource management on heterogeneous systems
- Automated parallelization and compiler techniques (Autotuning)
- Programming solutions using AI code generation
- Heterogeneous Solutions for HPC and Scientific Applications
- Parallel and distributed algorithms
- Parallel libraries and frameworks
- Parallel processing on heterogeneous systems
- Heterogeneous (included Non-von Neuman) Architectures
- Power/energy management
- Heterogeneous architectures for emerging application domains
- Architecture designs including Non-von Neuman architectures, memory and interconnection
- Reliability/Benchmarking/Measurements
- Debugging, performance tools and techniques
- Fault tolerance and resilience
- Application/hardware benchmarks

Manuscript submission
We invite submissions of original, unpublished research and experiential papers. Full papers should be between 6 to 8 pages in length, formatted according to the standard ACM two-column conference template. Additionally, we are introducing a short paper track for submissions up to 3 pages. ACM templates for both Microsoft Word and LaTeX can be accessed here. All paper submissions will be managed electronically via TBA.
Proceedings
All accepted papers will be published in the ExHET-PPoPP Workshops 2024 proceedings by the ACM Digital Library.
Best Paper Award
The Best Paper Award will be selected on the basis of explicit recommendations of the reviewers and their scoring towards the paper’s originality and quality.
Special Issue Journal
Selected best papers of ExHET will be considered for publication in a special issue of the international journal Applied Sciences (Heterogeneous Computing Solutions) and FGCS (High-performance Computing Heterogeneous Systems and Subsystems)
