    puting of linear inverse problems using iterative solvers [20], such as personalized PageRank [21], [22] and signal recovery on large graphs [23]–[25]. We focus on iterative methods for solving these linear systems. For the personalized PageRank problem, we study the power-iteration method which is the most classical PageRank algorithm [21]. We focus on the use of iterative methods for solving large sparse systems of linear equations. Many methods exist for solving such problems. The trick is to find the most effective method for the problem at hand. Unfortunately, a method that works well for one problem type may not work as well for another. Indeed, it may not work at all.

Dynamic Load Balancing • To achieve best performance of a parallel computing system running a parallel problem, it’s essential to maximize processor utilization by distributing the computation load evenly or balancing the load among the available processors while minimizing overheads.

This code provides a linear solver based on a parallel application of Cramer's rule. The programming was done in 'C' leveraging the MPI-CH2 libraries for message passing between nodes. This implementation is for dense linear systems and all. For equation systems from real problems, we demonstrated that the DSC algorithm combined with repartitioning and reordering is a well suited parallel iterative solver for circuit simulation.

Abstract The efficiency of parallel iterative methods for solving linear systems, arising from real- life applications, depends greatly on matrix characteristics and on the amount of parallel overhead.

It is often viewed that a major part of this overhead can be caused by parallel matrix-vector multiplications.In this section, we classify load balancing algorithms and discuss their applicability to data-intensive iterative routines and dedicated computational clusters with memory heterogeneity.

Load balancing algorithms can be either static or dynamic. Static algorithms [4, 5, 6] use a priori information about the parallel application and platform. This.Parallel Linear System Solvers for Runge-Kutta Methods P.J.
