摘要
In a previous work we proposed a new model that predicts the execution time of a regular application on a heterogeneous parallel environment. The model considers that a heterogeneous cluster is composed by distinct types of processors, accelerators and networks. This work further details and proposes some modifications to the original model, as well as evaluate it on a heterogeneous cluster environment. The results have show that the worst error in the estimations of the parallel execution time was about 12.7%, and, in many cases, the estimated execution time is equal to or very close to the actual one.
