ESSA 2025 : 6th Workshop on Extreme-Scale Storage and Analysis<br>
Held in conjunction with IEEE IPDPS 2025 - June 4th, 2025<br>

==========<br>
OVERVIEW:<br>
==========<br>
<br>
Advances in storage are becoming crucial as HPC and cloud systems handle ever-increasing data, a trend expected to accelerate. For decades, parallel file systems like Lustre and GPFS have seen few structural changes, with limited integration of I/O support
technologies that leverage hierarchical storage layers, such as node-local burst buffers. Recently, however, there has been a surge in innovations in data storage, processing systems, and I/O support software for several key reasons:<br>
<br>
- Technology: The growing availability of persistent solid-state storage and storage-class memory technologies, capable of replacing both memory and disk, is opening up new possibilities for the design of storage systems.<br>
<br>
- Performance requirements: Disk-based parallel file systems are no longer sufficient to meet the performance demands of high-end systems. However, the optimal use of solid-state storage and storage-class memory to achieve the required performance remains unclear.
As a result, new approaches for integrating these technologies into HPC systems are being actively developed and evaluated.<br>
<br>
- Application evolution: Data analysis applications, such as graph analytics and machine learning, are becoming increasingly critical in both scientific and commercial computing. I/O often presents a major bottleneck for these applications, particularly in
cloud and HPC environments, where rapid turnaround or the integration of intensive computation and analysis is required. As a result, data storage, I/O, and processing demands are evolving, driven by the emergence of complex workflows that integrate computation,
analytics, and learning.<br>
<br>
- Infrastructure evolution: In the future, HPC technology will extend beyond dedicated supercomputing centers. Concepts such as "Embedded HPC," "HPC in a Box," "HPC in the Loop," "HPC in the Cloud," "HPC as a Service," and "near-real-time simulation" will drive
the need for new, small-scale HPC deployment environments. To enable a seamless computing continuum, a federation of systems and functions will be needed, with unified mechanisms for managing I/O, storage, and data processing across all participating systems.<br>
<br>
- Virtualization and disaggregation: As virtualization and disaggregation become more widely adopted in cloud and HPC computing, the importance of virtualized storage is growing. Increased efforts will be required to understand its impact on performance.<br>
<br>
Our goals for the ESSA Workshop are to bring together leading researchers and developers in data-related fields?such as storage, I/O, processing, and analytics?on extreme-scale infrastructures, including HPC systems, clouds, edge systems, and hybrid combinations
of these. We aim to discuss advancements and potential solutions to the new challenges we encounter.<br>
<br>
- Extreme-scale storage systems for high-end HPC infrastructures, clouds, or hybrid environments<br>
- Extreme-scale parallel distributed, storage architectures<br>
- Synergies between different storage models, including POSIX file systems, object storage, key-value stores, and row- and column-oriented databases
<br>
- Structures and interfaces for leveraging persistent solid-state storage and storage-class memory<br>
- High-performance I/O libraries and services<br>
- I/O performance in extreme-scale systems and applications (HPC, clouds, edge)<br>
- Storage and data processing architectures for hybrid HPC/cloud/edge infrastructures supporting complex workflows that integrate simulation and analytics<br>
- Integrating computation within the memory and storage hierarchy to facilitate in-situ & in-transit data processing<br>
- I/O characterization and data processing techniques for application workloads in extreme-scale parallel and distributed machine learning and deep learning<br>
- Tools and techniques for managing data movement among compute and data-intensive components<br>
- Data reduction and compression methods<br>
- Failure management and recovery strategies for extreme-scale storage systems<br>
- Benchmarks and performance tools for extreme-scale I/O<br>
- Language and library support for data-centric computing<br>
- Storage virtualization and disaggregation<br>
- Ephemeral storage media and consistency optimizations<br>
- Storage architectures and systems for scalable stream-based processing<br>
- Case studies of I/O services and data processing architectures across various application domains (e.g., scientific simulations, experimental facilities, large observatories, bioinformatics, etc.)<br>
