摘要：

Balancing the workload distribution in a parallel environment is an important measure to reduce the total runtime of a parallel program. Since load balancing involves a significant amount of inter-processor communication the main problem is to keep this overhead as low as possible while at the same time trying to keep the workload as evenly distributed as possible. This task is particularly difficult in multi-phase calculations like in the simulation of reactive gas flows. In this paper we present a balancing strategy which reduces the problem of multiple phases to a single phase problem by reordering calculations within the timestep loop.
