As high-performance computing device, the GPU has exposed bandwidth and latency bottlenecks in on-chip interconnect and off-chip memory access. To eliminate such bottlenecks, we employ silicon nanophotonics and 3D stacking technologies in GPU microarchitecture. This provides higher communication bandwidth and lower latency signaling mechanisms at reduced(More)
Observations and theoretical simulations have established a framework for galaxy formation and evolution in the young Universe. Galaxies formed as baryonic gas cooled at the centres of collapsing dark-matter haloes; mergers of haloes and galaxies then led to the hierarchical build-up of galaxy mass. It remains unclear, however, over what timescales galaxies(More)
