Abstract
Data parallel implementation of the thermo-viscoelastic finite element algorithm with a conjugated gradient method on the CM-5 is presented. The performance of thermo-viscoelastic finite element procedures on massively parallel processing machines is conducted. Parametric studies on the CM-5 as well as the CRAY Y-MP and benchmarks for various problem sizes are also evaluated. The performance of the conjugate gradient method on the CRAY Y-MP and CM-5 is evaluated and is compared with ones of the CRAY sparse matrix and the Feable solvers. Using the 4 node plane element and 256-processor CM-5, a speedup factor of about 22 over the CRAY Y-MP was obtained for calculating 1.6x105 element stiffness matrices, which is 1.65 Gflops. For the 320,800 DOF case, the CM-5 with 256-processors was faster by a factor of 7 than the CRAY Y-MP.
