RSDHA 2026:
4th Workshop on Redefining Scalability for
Diversely Heterogeneous Architectures
Held in conjunction with HPCAsia’26
Osaka, Japan
January 26, 2026
(http://hpss.mines.edu/rsdha-26/)
============================================================
–Summary–
Recent trends toward the end of Dennard scaling and Moore’s law makes
the current and upcoming computing systems more specialized and complex,
consisting of more complex and heterogeneous architectures in terms of
processors, memory hierarchies, on-chip-interconnection networks,
storage, etc. This trend materialized in the mobile and embedded market,
and it is entering the enterprise, cloud computing, and high performance
computing markets.
RSDHA is a forum for researchers and engineers in both HPC domain and
embedded/mobile computing domain to gather together and discuss (1) the
latest ideas and lessons learned from the previous experience on
traditional (i.e., horizontal) and heterogeneity-based (i.e., vertical)
scaling in their own domains and (2) possible synergistic approach and
interaction between the two domains to find a good balance between
programmability and performance portability across diverse ranges of
heterogeneous systems from mobile to HPC.
–Scope and Goals–
The RSDHA workshop aims to serve as a forum for investigating the
un-explored region of the two-dimensional space of traditional
node-based (i.e., horizontal) and heterogeneity-based (i.e., vertical)
scaling of the current and upcoming HPC and mobile/embedded systems.
The scope of this workshop can be categorized in two primary areas:
1) Vertical Scaling, which will cover the studies that will enable HPC
applications to utilize a more diverse range of processors, and
2) Horizontal Scaling, which will cover the studies that investigate the
application of the traditional HPC techniques to the mobile and
autonomous systems to beat the multi-node scalability challenges as the
mobile/embedded systems become increasingly more connected.
–Research Areas of Interest–
The research areas of interest include but are not limited to:
– Performance-portable parallel programming paradigms for emerging
accelerator types
– Runtimes for arbitrary degrees of heterogeneous diversity
– Analytical modeling for general-purpose and domain-specific
programmable accelerators
– Application of heterogeneous programming/scheduling techniques used
in embedded and mobile computing to HPC systems and vice versa
– Communication and memory access challenges for clustered execution
of highly diverse platforms
– Analytical resource consumption modeling and decision making
mechanisms for edge-cloud and HPC systems
– Compositional resource management and workload balancing across the
collaborative clusters
– Fault tolerant and resilient execution for mobile/autonomous
systems and HPC systems
– Case studies using the vertical/horizontal scaling techniques
–Submissions–
– Authors are invited to submit original papers in two separate tracks:
– Full Paper: submit regular research papers in a single-column format with
at least 10 pages and at most 18 pages in length, which include tables, figures, and references.
