Charter:

Address programming environments for both existing legacy codes and alternative programming models to maintain continuity of current practices, while also enabling advances in software development, debugging, performance tuning, maintenance, interoperability and robustness. Establish key strategies and initiatives required to improve time to solution and ensure the viability and sustainability of applying HEC systems by the end of the decade.

Guidelines and Questions:

• Assume two possible paths to future programming environments:
  • incremental evolution of existing programming languages and tools consistent with portability of legacy codes
  • innovative programming models that dramatically advance user productivity and system efficiency/performance
• Specify requirements of programming environments and programmer training consistent with incremental evolution, including legacy applications
• Identify required attributes and opportunities of innovative programming methodologies for future HEC systems
• Determine key initiatives to improve productivity and reduce time-to-solution along both paths to future programming environments
• Example Topics:
  • Programming models, portability, debugging, performance tuning, compilers
