           ScalA21: 12th Workshop on Latest Advances in
           Scalable Algorithms for Large-Scale Systems

                  held in conjunction with the
     SC21: The International Conference on High Performance
           Computing, Networking, Storage and Analysis

     in cooperation with the IEEE Computer Society Technical
        Consortium on High Performance Computing (TCHPC)

               November 19, 2021, St. Louis, MO, USA
                                     (Virtual Event)


Novel scalable scientific algorithms are needed in order to enable key
science applications to exploit the computational power of large-scale
systems. This is especially true for the current tier of leading petascale
machines and the road to exascale computing as HPC systems continue to scale
up in compute node and processor core count. These extreme-scale systems
require novel scientific algorithms to hide network and memory latency, have
very high computation/communication overlap, have minimal communication, and
have no synchronization points. With the advent of Big Data and AI in the
past few years the need of such scalable mathematical methods and algorithms
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. Finally, with the advent of heterogeneous
compute nodes that employ standard processors as well as GPGPUs, scientific
algorithms need to match these architectures to extract the most performance.
This includes different system-specific levels of parallelism as well as
co-scheduling of computation. Key science applications require novel
mathematical models and system software that address the scalability and
resilience challenges of current- and future-generation extreme-scale HPC
