5th International Workshop on Legacy HPC Application Migration

To be held in conjunction with CANDAR'17, Aomori, Japan, November 19-22, 2017

In HPC software development, a high priority is given to performance. Many application developers usually adapt their application programs for a particular system to fully exploit the potential of the system with system-specific optimizations. Whenever their target system is updated to an emerging system, they are required to evolve the application programs to maximize the performance on the new generation system. This is so-called legacy HPC application migration. The migration cost increases with the hardware complexity of target systems, and moreover, future HPC systems are expected to be extremely massive and heterogeneous. Therefore, software evolution will require more efforts and will be essential for scaling up the performance in the upcoming extreme-scale computing era.

The goal of this workshop is to share practices and experiences on software evolution such as modernizing legacy applications on the latest HPC systems, and also discuss coming and developing technologies and research directions to improve the performance and productivity of applications on emerging systems. In particular, we will focus on the following topics of interest, but not limited to:

  • Programming models, languages and frameworks for facilitating HPC software evolution and refactoring.
  • Algorithms and implementation methodologies for future-generation computing systems, including manycores and accelerators (GPUs, Xeon Phi, etc).
  • Automatic performance tuning techniques, runtime systems and domain-specific languages for hiding the complexity of underlying system architectures.
  • Practices and experiences on porting of legacy applications and libraries.

Paper format

  • Regular paper: 5-7 pages
  • Poster paper: 3-4 pages
