"A multilevel approach to algorithm and software design for exaflops supercomputers" Glinskiy B.M., Kulikov I.M., Snytnikov A.V., Chernykh I.G., and Weins D.V. |
|
A strategy is proposed for the development of algorithms and software for exaflops supercomputers. This strategy consists of three stages. The first stage is the co-design understood as considering the architecture of the supercomputer at all steps of the development of the code. The second stage is the forward-looking development of algorithms and software for the most promising exaflops supercomputers. The forward-looking development is based on the simulation of the algorithm behavior within a given supercomputer architecture. The third stage is the estimation of energy efficiency of the algorithm with various implementations for a particular architecture or for different supercomputer architectures. The proposed approach is illustrated by the examples of solving two problems from astrophysics and plasma physics. Keywords: exascale computing, co-design, energy efficiency, agent simulation.
