International Workshop on Legacy HPC Application Migration

To be held in conjunction with CANDAR'15, Sapporo, Japan, December 8-11, 2015.

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.

This workshop is held as one of colocated workshops of CANDAR'15: http://is-candar.org/
