Colloq: Abstract: 
There is growing evidence that current architectures do not well handle cache-unfriendly applications such as sparse matrix operations, data analytics, and graph algorithms. This is due, in part, to the irregular memory access patterns demonstrated by these applications, and in how remote memory accesses are handled. This talk introduces a new, highly-scalable PGAS memory-centric system architecture where migrating threads travel to the data they access. A multi-threaded programming model based on Cilk has proven a highly efficient match to both these new applications and the Emu architecture. The first implementation of this architecture is discussed. Comparison of key parameters with a variety of today’s systems, with different system architectures, demonstrates the advantages. Early projections of performance against several well-documented kernels translate these advantages into comparative numbers. The next generation implementations of this architecture will expand these performance advantages very significantly.
