Virtual Institute – High Productivity Supercomputing

3rd Workshop on Extreme-Scale Programming Tools

SC14

Date

Monday 17 November 2014
09:00-17:30

Location

Held in conjunction with SC14:
The International Conference for High Performance Computing, Networking, Storage and Analysis
Ernest N. Morial Convention Center, Room 297
New Orleans, Louisiana, USA

Approaching exascale, architectural complexity and severe resource limitations with respect to power, memory and I/O make tools support in debugging and performance optimization more critical than ever before. However, the challenges mentioned above also apply to the tools development and, in particular, raise importance of topics such as automatic tuning and methodologies for exascale tools-aided application development. This workshop will serve as a forum for application, system, and tool developers to discuss the requirements for future exascale-enabled tools and the roadblocks that need to be addressed on the way. We also encourage application developers to share their experiences using tools.

The workshop is third in a series at SC conferences organized by the Virtual Institute - High Productivity Supercomputing in collaboration with the Priority Programme "Software for Exascale Computing" of the German Research Foundation (DFG). SPPEXA supports travel grants for participation of six students.

Workshop topics

  • Programming tools, such as performance analysis and tuning tools, debuggers, IDEs
  • Methodologies for performance engineering
  • Tool technologies tackling extreme-scale challenges, such as scalability, resilience, power, etc.
  • Tool infrastructures
  • Application developer experiences with programming tools
