This paper reviews earlier studies on superluminal wave propagation in anomalously dispersive media that have been carried out in the electronic, microwave, and optical regimes. Those studies are relevant to observation of modulated Gaussian pulses transmitted through various media at speeds apparently faster than c without distortion. This paper also presents the condition for superluminal propagation...
Live streaming systems based on application layer multicast (ALM) technology provide an effective and scalable way for content dissemination. Especially push-based systems, maintaining an explicit distribution topology, represent a promising approach. Compared to a classical client-server content distribution and in contrast to other ALM systems, they introduce only low additional transport delay...
ATOLL (Atomic Low Latency) is the synonym for a new cluster technology centered around an ASIC chip design integrating all logic parts of a complete System Area Network. Besides its unique architecture, ATOLL extends the hardware support for data transfer over the network to a limit, thus reducing communication latencies and enhancing concurrency. The paper presents the chip's key functionality (the...
ATOLL (Atomic Low Latency) is a new high speed interconnect solution for cluster computing. It is equipped with a fully integrated network on a chip, which is currently a unique feature. Therefore hostinterface, network interface and switch come as one, integrated, single solution. Moreover, the network interface card allows for dynamic re-configuration during runtime. This includes dynamic profiling...
