The solution of elliptic diffusion operators is the computational bottleneck in many simulations in a wide range of engineering and scientific disciplines. We present a truly scalable-ultrascalable-linear solver for the diffusion operator in unstructured elasticity problems. Scalability is demonstrated with speedup studies of a non-linear analyses of a vertebral body with over a half of a billion degrees of freedom on up to 4088 processors on the ACSI White machine. This work is significant
