Increasing the Scale of LS-DYNA® Implicit Analysis
Cray, LSTC, NCSA, and Rolls-Royce formed a partnership to explore the future of implicit computations as the scale of both finite element models and the systems they run on increase. Rolls-Royce created a family of dummy engine models, using solid elements, with as many as 200,000,000 degrees of freedom. NCSA ran these with specialized LS-DYNA variants, generated by Cray, on their Blue Waters machine, a hybrid Cray XE/XK system with 360,000 AMD cores. Processing and memory bottlenecks revealed themselves as the number of processors increased by an order-of-magnitude beyond that familiar to today’s developers and users, and LSTC made improvements to LS-DYNA.
