                    Call for Participation:

           ScalAH22: 13th Workshop on Latest Advances in
     Scalable Algorithms for Large-Scale Heterogeneous Systems

                    held in conjunction with
     SC22: The International Conference on High Performance
           Computing, Networking, Storage and Analysis

          in cooperation with the IEEE Computer Society

          8:30AM-5PM, November 13, 2022, Dallas, TX, USA

    Room C146, Kay Bailey Hutchison Convention Center Dallas
             650 S Griffin St, Dallas, TX 75202

Novel hybrid scalable scientific algorithms are needed with the advent of
variety of novel accelerators including graphics processing units (GPUs),
field-programmable gate arrays (FPGAs) as well as with the growth of the size
of quantum computing devices and neuromorphic chips and various artificial
intelligence (AI) specific processors. This myriad of devices requires an
unified hybrid approach that allows efficient and scalable hybrid approaches
combining classical and novel computing paradigms to be implemented at scale.
These extreme-scale heterogeneous systems require novel scientific algorithms
to hide the complexity, hide network and memory latency, have advanced
communication, and have no synchronization points where possible. With the
advent of AI in the past few years the need of such scalable mathematical
methods and algorithms for such hybrid architectures that are able to handle
data and compute intensive applications at scale becomes even more important.

Scientific algorithms for multi-petaflop and exa-flop systems also need to be
fault tolerant and fault resilient, since the probability of faults increases
with scale. Resilience at the system software and at the algorithmic level is
needed as a crosscutting effort. Key science applications require novel
mathematics and mathematical models and system software that address the
scalability and resilience challenges of current- and future-generation
extreme-scale heterogeneous high performance computing (HPC) systems.

Topics of interest include, but are not limited to:
---------------------------------------------------

- Novel scientific algorithms that improve performance, scalability, resilience
  and power efficiency on hybrid architectures
- Porting scientific algorithms and applications to hybrid and heterogeneous
  architectures (with different accelerators, hybrid classical/quantum,
  classical/AI accelerated, etc.)
- Crosscutting approaches (system software and applications) in addressing
  scalability challenges on hybrid architectures
- Naturally fault tolerant, self-healing or fault oblivious scientific
  algorithms for hybrid architectures
- Methods and algorithms for silent data corruption with systems at scale
- Ensuring algorithms scalability over various accelerator partitions/islands,
  and taking advantage where the system itself has different kinds of
  specialized compute nodes
