A NEW HIGH PERFORMANCE SPARSE STATIC SOLVER IN FINITE ELEMENT ANALYSIS WITH LOOP-UNROLLING
Chen Chen, Pu Pu, Sun, Shuli · 固体力学学报：英文版 · 2005
In the previous papers, a high performance sparse static solver with two-level unrolling based on a cell-sparse storage scheme was reported. Although the solver reaches quite a high efficiency for a big percentage of finite element analysis benchmark tests, the MFLOPS (million floating operations per second) of LDLT factorization of benchmark tests vary on a Dell Pentium Ⅳ 850 MHz machine from 100 to 456 depending on the average size of the super-equations, i.e.,on the average depth of unrolling. In this paper, a new sparse static solver with two-level unrolling that employs the concept of master-equations and searches for an appropriate depths of unrolling is proposed. The new solver provides higher MFLOPS for LDLT factorization of benchmark tests,and therefore speeds up the solution process.
