*** N.B.: Submission deadline extended *** ======================================================================== Second International Workshop on High-performance Infrastructure for Scalable Tools (WHIST 2012) Held in conjunction with the 17th ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming (PPoPP 2012) February 25-29, 2012 New Orleans, LA, USA http://whist-workshop.org ======================================================================== 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 Visit http://whist-workshop.org for more information. SPECIAL JOURNAL ISSUE --------------------- All papers from the workshop will be made available online, and selected papers will be published in a special journal issue. Details TBD.
