FaST: Find a Suitable Topology for Exascale Applications

"Find a Suitable Topology for Exascale Applications" (FaST) is a research project funded by the German Ministry of Education and Research. It deals with the temporal and spatial placement of processes on high performance computers of the future. It is widely assumed that the current trend in hardware development will continue and that the CPU performance will therefore grow considerably faster than the I/O performance. In order to prevent that these resources become bottlenecks in the system, FaST develops a new scheduling concept which monitors the system resources and locally adapts the distribution of the jobs. For monitoring the system a new agent-based system will be developed. The adaptations to the schedule will be realized by process migration. The effectiveness of the concept will be demonstrated in a prototype implementation using applications like LAMA and mpiBLAST.
