REX-IO 2023: 3rd Workshop on Re-envisioning Extreme-Scale I/O for
Emerging Hybrid HPC Workloads

Held in conjunction with IEEE Cluster 2023, Santa Fe, NM, USA.

Workshop Date: October 31, 2023



Scope, Aims, and Topics
High Performance Computing (HPC) applications are evolving to include 
not only traditional modeling and simulation bulk-synchronous scale-up 
workloads but also scale-out workloads, including artificial 
intelligence (AI), big data analytics methods, deep learning, and 
complex multi-step workflows. With the advent of Exascale systems such 
as Frontier, workflows include multiple different components from both 
scale-up and scale-out communities operating together to drive 
scientific discovery and innovation. With the often conflicting design 
choices between optimizing for write- vs. read-intensive, having 
flexible I/O systems is crucial to support hybrid workloads. Another 
performance aspect is the intensifying complexity of parallel file and 
storage systems in large-scale cluster environments. Storage system 
designs are advancing beyond the traditional two-tiered file system and 
archive model by introducing new tiers of temporary, fast storage close 
to the computing resources with distinctly different performance 

The changing landscape of emerging hybrid HPC workloads along with the 
ever increasing gap between the compute and storage performance 
capabilities reinforces the need for an in-depth understanding of 
extreme-scale I/O and for rethinking existing data storage and 
management techniques. Traditional approaches of managing data might 
fail to address the challenges of extreme-scale hybrid workloads. Novel 
I/O optimization and management techniques integrating machine learning 
and AI algorithms, such as intelligent load balancing and I/O pattern 
prediction, are needed to ease the handling of the exponential growth of 
data as well as the complex hierarchies in the storage and file systems. 
Furthermore, user-friendly, transparent and innovative approaches are 
essential to adapt to the needs of different HPC I/O workloads while 
easing the scientific and commercial code development and efficiently 
utilizing extreme-scale parallel I/O and storage resources.

Established at IEEE Cluster 2021, the Re-envisioning Extreme-Scale I/O 
for Emerging Hybrid HPC Workloads (REX-IO) workshop has created a forum 
for experts, researchers, and engineers in the parallel I/O and storage, 
compute facility operation, and HPC application domains. REX-IO solicits 
novel work that characterizes I/O behavior and identifies the challenges 
in scientific data and storage management for emerging HPC workloads, 
introduces potential solutions to alleviate some of these challenges, 
and demonstrates the effectiveness of the proposed solutions to improve 
I/O performance for the exascale supercomputing era and beyond. We 
envision that this workshop will contribute to the community and further 
drive discussions between storage and I/O researchers, HPC application 
users and the data analytics community to give a better in-depth 
understanding of the impact on the storage and file systems induced by 
emerging HPC applications.

Topics of interest include, but are not limited to:
- Understanding I/O inefficiencies in emerging workloads such as complex 
multi-step workflows, in-situ analysis, AI, and data analytics methods
- New I/O optimization techniques, including how ML and AI algorithms 
might be adapted for intelligent load balancing and I/O pattern 
prediction of complex, hybrid application workloads
- Performance benchmarking and modeling, and I/O behavior studies of 
emerging workloads
- New possibilities for the I/O optimization of emerging application 
workloads and their I/O subsystems
- Efficient monitoring tools for metadata and storage hardware 
statistics at runtime, dynamic storage resource management, and I/O load 
- Parallel file systems, metadata management, and complex data management
- Understanding and efficiently utilizing complex storage hierarchies 
beyond the traditional two-tiered file system and archive model
- User-friendly tools and techniques for managing data movement among 
compute and storage nodes
- Use of staging areas, such as burst buffers or other private or shared 
acceleration tiers for managing intermediate data between computation tasks
- Application of emerging big data frameworks towards scientific 
computing and analysis
- Alternative data storage models, including object and key-value 
stores, and scalable software architectures for data storage and archive
- Position papers on related topics

Submission Guidelines
All papers must be original and not simultaneously submitted to another 
journal or conference. Indicate all authors and affiliations. All papers 
will be peer-reviewed using a single-blind peer-review process by at 
least three members of the program committee. Submissions should be a 
complete manuscript. Full paper submissions should not exceed 6 
single-spaced, double-column pages using 10-point size font on 8.5 X 11 
inch pages (IEEE conference style, 
https://www.ieee.org/conferences/publishing/templates.html) including 
everything excluding references.

Papers are to be submitted electronically in PDF format through 
EasyChair. Submitted papers should not have appeared in or be under 
consideration for a different workshop, conference or journal. It is 
also expected that all accepted papers will be presented at the workshop 
by one of the authors.

All accepted papers (subject to post-review revisions) will be published 
in the IEEE Cluster 2023 proceedings.
