    ELSEYlER Computer methods in applied mechanics and engineering Comput. Methods Appl. Mech. Engrg. 130 (1996) 299-318 An incremental elastic-plastic Finite Element solver in a workstation cluster environment Part II. Performance of a first implementation Anna Feriani, Francesco Genna* Department of Civil Engineering, University of Brescia, 25123 Brescia, Italy Received 23 February 1995; revised 5 July 1995 Abstract This work illustrates results obtained by implementing in a parallel computer environment the i rate formulation of the theory of plasticity and its integration scheme as illustrated in the preceding Part I. The Preconditioned Conjugate Gradient is used as a tool for repeatedly solving linear systems of equations. Although the investigation about the performance of the workstation cluster as a parallel virtual computer is still far from being completed, it is already possible to conclude that, in such an environment, several techniques proposed for reducing the computer time required by the iterative solver are not applicable. One purpose of the work is therefore to give guidelines in terms of expected performances of the Conjugate Gradient method when applied to stiff problems, in which the condition number may shoot up to the billions. Even if the implemented computer code is not based on the most convenient rate formulation in terms of parallelizability, as shown in Part I of this work, the obtained results indicate anyway that, for some categories of structural problems, the development of a parallel, element-by-element computer code is a promising line of work. 1. Introduction After examining, in Part I of this work, the merits and drawbacks of two different rate formulations of the elastic-plastic structural problem discretized by Finite Elements, we now intend to illustrate the results obtained by implementing one of those formulations on a particular parallel computing environment, defined by the clustering via network of three workstations. The illustration of such results is meant to put forward the following aspects, part general and part specific of the particular hardware and software utilized. (i) At the present stage of development of both hardware and software, in the field of parallel computing, there is still the need of carefully taking into account the coupling between theory and practice by which each algorithm is best suited for a particular hardware and software environment. There are no general rules, even for those fields where the mathematics are well developed, such as that of solution techniques for linear systems of equations. Despite this aspect, which may be in the process of disappearing if the parallel computing techniques will reveal as winners, in Part I of this work we have attempted to describe and analyze solution strategies for non-linear structural problems in a fairly general way also with respect to * Corresponding author. 00457825/96/$15.00 0 1996 Elsevier Science S.A.
