Approximate computing has gained research attention recently as a way to increase energy
efficiency and/or performance by exploiting some applications' intrinsic error resiliency …

The Blue Gene®/L computer is a massively parallel supercomputer based on IBM system-on-
a-chip technology. It is designed to scale to 65,536 dual-processor nodes, with a peak …

As the scales of parallel applications and platforms increase the negative impact of
communication latencies on performance becomes large. Fortunately, modern High …

Network technology is the basis for large-scale high-efficiency network computing, such as
supercomputing, cloud computing, big data processing, and artificial intelligence computing …

We examine the ability of CMPs, due to their lower on-chip communication latencies, to
exploit data parallelism at inner-loop granularities similar to that commonly targeted by …

Many current parallel computers are built around a torus interconnection network. Machines
from Cray, HP, and IBM, among others, make use of this topology. In terms of topological …

While medium-and large-sized computing centers have increasingly relied on clusters of
commodity PC hardware to provide cost-effective capacity and capability, it is not clear that …

The TOP500 is a treasure trove of information on the leading edge of high performance
computing. It was used in the 2008 DARPA Exascale technology report to isolate out the …

As the scales of parallel applications and platforms increase the negative impact of
communication latencies on performance becomes large. Random network topologies can …

Whereas efficient barrier implementations were once a concern only in high-performance
computing, recent trends in core integration make the topic relevant even for general …
