Among the high-radix and low-diameter networks, fat-tree topology is commonly used in HPC and datacenter systems. Resource and job management is critically important to mitigate application interference in order to achieve high system performance and utilization. Preliminary studies have shown the effect of job placement on parallel scientific applications performance. In this work we study interference...
To alleviate the growing concern of energy waste in networked devices, we propose an energy saving strategy in the ``server-centric" data center network. Focusing on servers, we introduce a basic scheme based on the transition of automata. By changing efficiently from sleeping state to active state in different network traffic, servers save the energy. This scheme is self-adaptive and simple...
A time-varying matching scheme designed for pulse- based high-quality factor (Q) receiving systems is introduced and analyzed. The proposed technique takes advantage of the time-domain characteristics of the short-duration pulses in a way that the matching network is optimized for absorbing energy from the pulse within its duration, and is reconfigured after the pulse so that the captured energy is...
Nowadays, the real practice of network coding in wireline networks is focused on the P2P overlay networks. Although it can help to utilize network resources more efficiently, P2P network coding does not exhibit benefits in terms of the maximum throughput. Our work aims to implement network coding at the IP layer, which is an idea not fundamentally new, but with little real practice because of the...
In this paper a time-varying matching network is proposed for signal-centric systems. This antenna matching network achieves significantly higher bandwidth than conventional designs with the same circuit topology and complexity. This is achieved by exploiting information about the incident pulse. Time- varying elements control the initial conditions of the reactive components so that excellent matching...
