Reaching the goal of exascale will require massive improvements in hardware performance, power consumption, software scalability, and usability. To address these issues Sandia National Labs is leading the UHPC X-Caliber Project, with the goal of producing a prototype single cabinet capable of a sustained petaflop by 2018. Our approach focuses on solving the data movement problem with advanced memory and silicon photonics, enabled by advances in fabrication and 3D packaging, and unified by a new execution model. I present the current X-Caliber architecture, our design space, and the co-design philosophy which will guide the project.

Extreme Scale AMR for Hydrodynamic Cosmology
Cosmological simulations present well-known difficulties scaling to large core counts because of the large spatial inhomogeneities and vast range of length scales induced by gravitational instability. These difficulties are compounded when baryonic physics is included which introduce their own multiscale challenges. In this talk I review efforts to scale the Enzo adaptive mesh refinement hydrodynamic cosmology code to O(100,000) cores, and I also discuss Cello--an extremely scalable AMR infrastructure under development at UCSD for the next generation of computer architectures which will underpin petascale Enzo.
