Abstract: | This paper presents new adaptations of two methods that solve large differential equations systems, to the grid context. The
first method is based on the Multisplitting concept and the second on the Waveform Relaxation concept. Their adaptations are
implemented according to the asynchronous iteration model which is well suited to volatile architectures that suffer from
high latency networks. Many experiments were conducted to evaluate and compare the accuracy and performance of both methods
while solving the advection-diffusion problem over heterogeneous, distributed and volatile architectures. The JACEP2P-V2 middleware
provided the fault tolerant asynchronous environment, required for these experiments. |
