Today's petascale supercomputers contain over 100,000 processor cores,
and thread counts on exascale systems are expected to exceed 100
million. Increasingly complex multicore and accelerator
node-architectures fuel the trend towards massive concurrency, and
new, hierarchical parallel programming models will be necessary to
take full advantage of future machines. With increased node, system,
and application complexity, scalable tools will be critical for
diagnosing the root causes of correctness and performance problems.

To diagnose problems at the extreme scale, tools themselves are
becoming more complex. Tools will require sophisticated infrastructure
to monitor, measure, analyze, 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. To manage this complexity, there is a need both
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 and operating system interoperability
* Scalable online and offline analysis techniques, including
- Techniques for managing large amounts of information
- Low-overhead online parallel data analysis techniques
* Monitoring, measurement and analysis approaches for novel parallel
programming models
- Tool support for multithreading, shared-memory, and hierarchical
parallelism, including interaction with language runtime and
operating systems
- Measurement and attribution techniques for new programming
paradigms
* Scalable presentation of results
