Workshop on Latest Advances in Scalable
Algorithms for Large-Scale Systems (ScalA) 2013
<http://www.csm.ornl.gov/srt/
held in conjunction with
SC13: The International Conference for High
Performance Computing, Networking, Storage and Analysis
in cooperation with ACM SIGHPC
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.
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 systems.
