We demonstrate MXQuery/H, a modified version of MXQuery that uses hardware acceleration to speed up XML processing. The main goal of this demonstration is to give an interactive example of hardware/software co-design and show how system performance and energy efficiency can be improved by off-loading tasks to FPGA hardware. To this end, we equipped MXQuery/H with various hooks to inspect the different...
Many professional cluster systems consist of nodes with different hardware configurations. Such heterogeneous environments require different load-balancing techniques than homogenous environments. The c-load-collision-protocol is able to achieve good results for data-management purposes. Using this protocol, we propose a way for load-balancing in interactive rendering environments. For this work,...
In this paper we present a modular ultra-wideband research and development platform for IEEE 802.15.4a. Besides standard conform operation, this platform also allows operation in a large variety of applications as well as easy adaptation to different frequency bands and coding schemes while common testbeds are mostly restricted to one application and frequency band. In this contribution, we describe...
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...
