  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

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.

Submission Guidelines

Authors are invited to submit manuscripts in English structured as 
technical papers not exceeding 8 letter size (8.5x11) pages including 
figures, tables and references using the IEEE format for conference 
proceedings. Submissions not conforming to these guidelines may be 
returned without review. Reference style files are available at 
<http://www.ieee.org/web/publications/pubservices/confpub/AuthorTools/conferenceTemplates.html.>

All manuscripts will be reviewed and judged on correctness, originality, 
technical strength, and significance, quality of presentation, and 
interest and relevance to the workshop attendees. Submitted papers must 
represent original unpublished research that is not currently under 
review for any other conference or journal. Papers not following these 
guidelines will be rejected without review and further action may be 
taken, including (but not limited to) notifications sent to the heads of 
the institutions of the authors and sponsors of the conference. 
Submissions received after the due date, exceeding length limit, or not 
appropriately structured may also not be considered. At least one author 
of an accepted paper must register for and attend the workshop. Authors 
may contact the workshop program chair for more information. Papers 
should be submitted electronically at: 
<http://www.easychair.org/conferences/?conf=scala2011.>

Important Dates:

Full paper submission:      12 September, 2011
Notification of acceptance: 17 October, 2011
Camera-ready submission:     7 November, 2011
Early registration:         17 October, 2011
