An efficient parallel implementation of the Everglades Landscape Fire Model Using checkpointing

摘要

This paper presents a low-communication overhead and high-performance data parallelism implementation of the Everglades landscape Fire Model (ELFM) in a network of worksta- tions(NOWs). ELFM is parallelized under Message Passing Interface(MPI). Checkpointing and rollback technologies are used to handle the spread of fire which is a dynamic and irreg- ular component of the model. A parallel application model with the mixture of a variety of asynchronous and synchronous computation is developed. In this model, the asynchronous computation is dominant and synchronous computation is intermittent.
