Iterative methods are used increasingly for solution of the extremely large matrix equations generated by integral equation analysis of multi-wavelength frequency domain scattering. Although much cheaper than direct methods, the matrix solution remains the dominant cost, and is very costly. The crit

Abstract
We present a massively parallel version of the single‐level fast multipole method, which allows the efficient use of hundreds of processors. A very large problem with more than 32 millions of unknowns is solved in 512 processors, which becomes a new record in scalability for this kind of problems. © 2009 Wiley Periodicals, Inc.

## Abstract A fast integral equation method, termed IE‐FFT, is applied with the combined field integral equation (CFIE) for solving electromagnetic scattering problems of three‐dimensional (3D) electrically large targets. For closed conducting surfaces, the employment of CFIE eliminates the interna

## Communicated by A. Piskorek This work proves global in time existence of large solutions for a quasistatic problem in non-linear viscoelasticity in the three-dimensional case. The basic idea is to apply the energy method for local in time solutions.
