Furthermore, the types of the parallel architectures are demonstrated and classified according to how the computing units are connected to a memory model. Two parallel systems are classified to the shared and distributed platforms. Depending on these two types, we are categorized the parallel programming models. The parallel iterative methods are explained and its two types, the synchronous and asynchronous iterative methods, are described. The synchronous iterative methods are well implemented over local homogeneous cluster with a high speed network link, while the asynchronous iterative methods are more conventional to implement over the distributed heterogeneous clusters. -Consequently, running these two types of the parallel iterative methods over distributed platforms is interested in this work.

The energy consumption model for measuring the energy consumption of the parallel applications from the related literature is described. This model cannot be used for all types of parallel architectures. The energy model is assumed to measure the dynamic power during both communication and computation times, while the processor involved remains idle during the communications time and only consumes static power. Moreover, it is not well adapted to the heterogeneous architectures. However, in the coming chapters of this thesis a new energy consumption models are developed, use for modeling and measuring the energies consumed by a parallel iterative methods running on both homogeneous and heterogeneous architectures. diff --git a/Thesis.tex b/Thesis.tex index 3a02c68..d402442 100644 --- a/Thesis.tex +++ b/Thesis.tex @@ -62,7 +62,6 @@ \include{CHAPITRE_02} \include{CHAPITRE_03} - \include{CHAPITRE_04} \part{Conclusion and Perspectives}
