The Juqueen architecture is composed of IBM PowerPC A2 at 1.6 GHz with speed network. +In many situations, using preconditioners is essential in order to find the +solution of a linear system. There are many preconditioners available in PETSc. +For parallel applications all the preconditioners based on matrix factorization +are not available. In our experiments, we have tested different kinds of +preconditioners, however as it is not the subject of this paper, we will not +present results with many preconditioners. In practise, we have chosen to use a +multigrid (mg) and successive over-relaxation (sor). For more details on the +preconditioner in PETSc please consult~\cite{petsc-web-page}. + -{\bf Description of preconditioners}\\ \begin{table*}[htbp] \begin{center} -- 2.39.5
