| Zusammenfassung |
| The Parallel Ocean Program (POP) is used in many strongly eddying
ocean circulation simulations. Ideally it would be desirable to be able to do
thousand-year-long simulations, but the current performance of POP
prohibits these types of simulations. In this work, using a new
distributed computing approach, two methods to improve the
performance of POP are presented. The first is a block-partitioning scheme for the optimization of the load balancing of
POP such that it can be run efficiently in a multi-platform
setting. The second is the implementation of part of the POP model
code on graphics processing units (GPUs). We show that the combination of
both innovations also leads to a substantial performance increase
when running POP simultaneously over multiple computational
platforms. |
