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. The emerging workloads introduce new I/O subsystems by advancing beyond the traditional two-tiered file system with potential performance bottlenecks in terms of I/O performance and scalability. Another performance aspect is the intensifying complexity of parallel file and storage systems in large-scale cluster environments. The changing landscape of emerging 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 workloads and for rethinking existing data storage and management techniques.
The 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 HPC 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.
The 1st Workshop on Re-envisioning Extreme-Scale I/O for Emerging Hybrid HPC Workloads (REX-IO) will be held on September 7, 2021 in conjunction with IEEE Cluster, Portland, Oregon, USA virtually.
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. Manuscript for full paper should be not exceed 6 single-spaced, double-column pages using 10-point size font on 8.5X11 inch pages (IEEE conference style) 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.
