Abstract

Performance evaluation of viscoelastic finite element supercomputer algorithms S. Yi, H.H. Hilton, M.F. Ahmad Urbana- Champaign Urbana, IL 61801, USA ABSTRACT The primary objectives of this study are performance evaluations of dy- namic viscoelastic finite element procedures and codes on vector and paral- lel processing machines. Parametric studies on various CRAY machine ar- chitectures and benchmarks for various problem sizes are also undertaken. CRAY hardware performance monitors such as Flowtrace and Perftrace tools are used to obtain performance data for subroutine program mod- ules and specified code segments. The performance of element stiffness computations is in the range of 121-183 mega floating-point operations per second (Mflops) on the NCSA CRAY-YMP. The performances of the Cray sparse matrix and the Feable solvers are also evaluated. INTRODUCTION The finite element method is a very attractive technique for solving bound- ary and initial value problems a
