Hierarchical Collectives in MPICH2
Abstract. Most parallel systems on which MPI is used are now hierarchical: some processors are much closer to others in terms of interconnect performance. One of the most common su...

Prediction of high-performance on-chip global interconnection
Different interconnection structures have been proposed to solve the performance limitation caused by scaling of on-chip global wires. In this paper, we give an overview of curre...

Partitioning of image datasets using discriminative context information
We propose a new method to partition an unlabeled dataset, called Discriminative Context Partitioning (DCP). It is motivated by the idea of splitting the dataset based only on how...

Clock Synchronization with Bounded Global and Local Skew
We present a distributed clock synchronization algorithm that guarantees an exponentially improved bound of O(log D) on the clock skew between neighboring nodes in any graph G of ...

Building Manycore Processor-to-DRAM Networks with Monolithic Silicon Photonics
We present a new monolithic silicon photonics technology suited for integration with standard bulk CMOS processes, which reduces costs and improves opto-electrical coupling compar...
