Hierarchical poly tree computer architectures defined by computational multidisciplinary mechanics
TL;DR: This paper will develop an alternative computer architecture called the Poly Tree which will explore the development of problem-dependent parallel networks of processors which will enable significant, often superlinear, speed enhancements; provide a logical/efficient framework for linear/nonlinear and transient structural mechanics problems; and provide an logical framework from which to apply model reduction procedures.
