NAMD is a parallel molecular dynamics code designed for high‐performance simulation of
large biomolecular systems. NAMD scales to hundreds of processors on high‐end parallel …

Building future generation supercomputers while constraining their power consumption is
one of the biggest challenges faced by the HPC community. For example, US Department of …

Summary form only given. We present a parallel simulator-BigSim-for predicting
performance of machines with a very large number of processors. The simulator provides …

A method of embedding a covert audio message in a cover utterance for secure
communication is presented. The covert message is represented in a compressed form with …

As high performance clusters continue to grow in size, the mean time between failures
shrinks. Thus, the issues of fault tolerance and reliability are becoming one of the …

Power has become a primary concern for HPC systems. Dynamic voltage and frequency
scaling (DVFS) and dynamic concurrency throttling (DCT) are two software tools (or knobs) …

As the size of supercomputers increases, the probability of system failure grows
substantially, posing an increasingly significant challenge for scalability. It is important to …

Job management software on peta-and exascale supercomputers continues to provide static
resource allocations, from a program's start until its end. Dynamic resource allocation and …

In this paper we present a design methodology for algorithm/architecture co-design of a
voltage-scalable, process variation aware motion estimator based on significance driven …

Processor virtualization via migratable objects is a powerful technique that enables the
runtime system to carry out intelligent adaptive optimizations like dynamic resource …
