Real space DFT (RSDFT) is a simulation technique most suitable for massively-parallel
architectures to perform first-principles electronic-structure calculations based on density …

Silicon nanowires are potentially useful in next-generation field-effect transistors, and it is
important to clarify the electron states of silicon nanowires to know the behavior of new …

We investigate scalability issues involved in developing high performance digital library
systems. Our observations and solutions are based on our experience with the Alexandria …

In addition to its use in local area networks, Ethernet has been used for connecting hosts in
the area of high-performance computing. Here, we investigated the impact of topology and …

Predicting how well applications may run on modern systems is becoming increasingly
challenging. It is no longer sufficient to look at number of floating point operations and …

As the complexity of parallel computers grows, constraints posed by the construction of
larger systems require both greater, and increasingly non-linear, parameter sets to model …

Inter-node communications between accelerators in heterogeneous clusters require extra
latency because of the time required to transfer data copies between the host and …

In Online Social Networks (OSNs), the important participants, the trust relations between
participants, and the interaction contexts between participants greatly impact a participant's …

The Installation and maintenance costs of dedicated interconnection networks for PC cluster
are still expensive, and they tend to increase the specializations and complexities because …

Due to advent of powerful and easily available Multi-Core PC clusters, the computation
performance of each node is dramatically increased and this trend will probably continue in …
