  2nd Workshop on Latest Advances in Scalable Algorithms
            for Large-Scale Systems (ScalA)

              held in conjunction with the

24th IEEE/ACM International Conference on High Performance
   Computing, Networking, Storage and Analysis (SC) 2011

          November 14, 2011, Seattle, WA, USA

  <http://www.csm.ornl.gov/srt/conferences/Scala/2011/>

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. Scientific 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.

Topics of interest include, but are not limited to:

- Novel scientific algorithms that improve performance,
  scalability, resilience and power efficiency
- Porting scientific algorithms and applications to
  many-core and heterogeneous architectures
- Performance and resilience limitations of scientific
  algorithms and applications at scale
- Crosscutting approaches (system software and
  applications) in addressing scalability challenges
- Scientific algorithms that can exploit extreme
  concurrency (e.g. 1 billion for exascale by 2018)
- Naturally fault tolerant, self-healing or fault
  oblivious scientific algorithms
- Programming model and system software support for
  algorithm scalability and resilience
