LHAM'16

4th International Workshop on Legacy HPC Application Migration

To be held in conjunction with CANDAR'16, Hiroshima, Japan, November 22-25, 2016.

In HPC software development, a high priority is given to performance. As system-specific optimizations are almost always required to fully exploit the potential of a system, application programmers usually optimize their application programs for particular systems. Whenever the target system of an application program is changed to a new one, thus, they need to adapt the program to the new system. This is so-called legacy HPC application migration. The migration cost increases with the hardware complexity of target systems. Since future HPC systems are expected to be extremely massive and heterogeneous, migration will require more efforts and will be essential for performance in the upcoming extreme-scale computing era. Therefore, this International Workshop on Legacy HPC Application Migration (LHAM) offers an opportunity to share practices and experience of legacy HPC application migration, and also discuss coming and developing technologies and research directions to reduce the migration cost.

Previous LHAM workshops:

Topics of interest include, but are not limited to

  • Programming models, languages and frameworks for supporting HPC application migration.
  • Algorithms and implementation schemes for future-generation computing systems.
  • Runtime systems for hiding the complexity of underlying system architectures.
  • Practices and experience of HPC application migration.

Title of the talk

Algorithmic Challenges of Legacy HPC Application Migration

Abstract

High performance computing clusters, SMP-machines, GPU- or Phi-based computing systems, vector computers, FPGA accelerators, small, medium or petascale supercomputers… Diversity of modern computing systems is great and their huge potential allows complex problems, previously thought impossible, to be solved. By now, computing community has developed highly valuable and wide spectrum of software with a hope to use this wealth of codes on the next generation computers for a long time. At the same time, the efficient usage of all opportunities offered by modern computing systems through a large number of applications represents a global challenge and requires new knowledge, skills and abilities, where one of the main roles belongs to understanding of key properties of parallel algorithms. The talk will address the urgent need for theoretical and practical technologies of an accurate and concerted design of highly parallel algorithms and extreme scaled applications to be able to solve large problems through a variety of different computing platforms. Deep understanding of algorithmic structures will provide a key to successful application migration while preserving a high level of efficiency.
