Call For Papers

Dear Colleagues,

The submission deadline for the 1st Workshop on Re-envisioning Extreme-Scale I/O for Emerging Hybrid HPC Workloads (REX-IO) has been extended by a week (from July 2nd to July 9th, 2021, 11:59PM AoE). Take advantage of this extension and submit your work. Position and vision paper submissions are highly welcomed as well.

Accepted papers will be published by IEEE as part of the Cluster 2021 Conference Proceedings. Manuscripts should not exceed 6 single-spaced, double-column pages using 10-point size font on 8.5X11 inch pages (IEEE conference style) including text and figures excluding references. For submission details, please see below or refer to our website: https://sites.google.com/view/rexio/

REX-IO will be organized virtually. Travel will not be required. We're looking forward to an engaging and productive workshop.

Kind regards,
Sarah Neuwirth
on behalf of the REX-IO 2021 Co-Chairs

REX-IO 2021: First Workshop on Re-envisioning Extreme-Scale I/O
for Emerging Hybrid HPC Workloads

Held in conjunction with IEEE Cluster 2021.

September 7, 2021, Virtual Meeting

(https://sites.google.com/view/rexio/)

================================
Scope, Aims, and Topics
================================
High Performance Computing (HPC) applications are evolving to include not only traditional scale-up modeling and simulation bulk-synchronous workloads but also scale-out workloads like artificial intelligence (AI), data analytics methods, deep learning, big data and complex multi-step workflows. Exascale workflows are projected to 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-intensive vs. read-intensive, having flexible I/O systems will be crucial to support these 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 characteristics.

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.

The Re-envisioning Extreme-Scale I/O for Emerging Hybrid HPC Workloads (REX-IO) workshop 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. We envision that this workshop will contribute to the community by analyzing emerging hybrid workloads, recognizing the gap in the data management methodologies, and providing novel techniques to improve I/O performance for the exascale supercomputing era and beyond. This workshop will also provide a platform to felicitate 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, resource management, 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 tools for the monitoring of metadata and storage hardware statistics at runtime, dynamic storage resource management, and I/O load balancing
● 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. All manuscripts will be reviewed by at least three members of the program committee. Submissions should be a complete manuscript. Manuscripts shall not exceed six (6) single-spaced, double-column pages using 10-point size font on 8.5X11 inch pages (IEEE conference format, https://www.ieee.org/conferences/publishing/templates.html) including text and figures 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.
