CALL FOR PAPERS
---------------
From laptops to supercomputers, increasingly complex multicore and
accelerator hardware is driving rapid growth in concurrency. At the
high end, exascale systems are expected to support over 100 million
threads, primarily due to increased intra-node concurrency. To take
full advantage of this increased concurrency, new software and
programming models are necessary. With increased system and
application complexity, scalable tools are critical for diagnosing the
root causes of performance and correctness problems.

To diagnose and correct problems in highly concurrent systems, tools
themselves are becoming more complex. Tools will require sophisticated
infrastructure to measure, analyze, diagnose and present the causes of
an execution's anomalies. In many cases, tools will combine online
and offline analysis. They may use sophisticated modeling and
statistical analysis techniques. They may attempt to correct
problems; and they may have to survive faults. To manage this
complexity, there is a need for abstractions that simplify tool design
and for infrastructure that is reusable and extensible.


SUBMISSIONS
-----------
We solicit papers on all aspects of scalable tool abstractions and
infrastructure, including (but not limited to):

* Generic, reusable tool-infrastructure components
* Tool-component interoperability
* Tool-runtime design, including
- Scalable data structures and data representation for tool runtimes
- Scalable tool-communication infrastructure
- Tool, language run time, and operating system interoperability
- Fault management
* Scalable online and offline attribution, data management, and
analysis techniques, including
- Techniques for managing large amounts of information
- Low-overhead online parallel data analysis techniques
* Monitoring, attribution, and analysis approaches for novel
parallel programming models
- Tool support for multithreading, shared-memory, and hierarchical
parallelism, including interaction with language runtimes and
operating systems
- Measurement and attribution techniques for new programming paradigms
* Scalable presentation of results
