Most of the disks used in the server market are currently based on RAID technology. The primary reason for introducing RAID technology in 1988 has been the fact that large disk systems have become much slower and more expensive than the connection of a large number of inexpensive disks and the use of them as an array. The times seem to repeat themselves. Today, large scale RAID arrays have become incredible big and expensive. It seems that it makes sense to replace them by a collection of smaller and inexpensive arrays of JBODs or mid-ranged RAID arrays. In this paper we will show that combining these systems with state-of-the-art virtualization technology can lead to a system that is faster and less expensive than an enterprise storage system, while being as easy to manage and as reliable. Therefore we will outline the most important features of storage management and compare there realization in enterprise class storage systems and in current and future virtualization environments.

Currently, most W-LAN networks rely on a centralized design with access points routing all inner and outbound traffic. These access points are intrinsic communication bottlenecks. Mobile Ad Hoc Networks (MANET) overcome this problem, because every participant works as well as a simple node and as a router. Current MANETs are restricted in scalability, because they rely on flooding mechanisms or complete routing tables. Other approaches, providing better scalability use clustering, yet network performance deteriorates in case of high node mobility. We describe the design of a PAMANET, the Paderborn Mobile Ad Hoc Network, a MANET overcoming these problems providing scalability and reliability in a mobile scenario. When implemented, PAMANET works with standard W-LAN IEEE 802.11 radio devices, provides IPv6 communication interfaces and works on personal computers under a standard Linux distribution. First, we present current routing protocols and classify them with respect to scalability and stability in dynamically evolving MANETs. Then, we discuss related research in the area of distributed hash tables and consistent hashing, used for relieving hot spots in the Web, storage area networks and peerto-peer networks, which inspires the design of PAMANET. PAMANET consists of three main components: First, the embedding of the routing layer into IEEE 802.11 and IPv6 by using techniques used at the ad hoc support library (aslib) by Gupta et al. Second, the routing layer which combines a landmark routing, hierarchical clustering, consistent hashing for providing location dependent addresses and lookup-service for the location of nodes. Third, a peerto-peer data storage system based on egoistic distributed caches enabling hop and traffic efficient data access on replicated data partitions.
The routing layer incorporates a variety of new approaches. Link distances reflect the failure probability of links, which is estimated by the reciprocal age of the link. Then, we combine a landmarking system on this metric with the hierarchical layer graph yielding small landmark addresses and small routing tables. To balance the load of the distributed lookup-service for landmark addresses, a hierarchical weighted consistent hashing scheme is used. This ensures that each node receives an equal part of all landmark addresses. Using these mechanisms (regularly and on demand) PAMANET adjusts IPv6 routing tables such that short stable routes are preferred. For the distribution of control data like landmark information PAMANET uses a message box system interface to provide fast one-hop communication. On top of this system, PAMANET provides a peer-to-peer data storage and lookup system that realizes time, traffic, and load efficient access using egoistic caches and data segmentation strategies.

Thereby, iSCSI greatly simplifies storage virtualization, since clients can access storage in a unified manner, no matter whether the I/O-path is short or long distance. Intermediate devices located on the path between a client and a target can easily intercept iSCSI sessions and rewrite packets for the sake of load balancing, prefetching, or redundancy, to mention just a few beneficial applications. Within this paper we describe the design and implementation of such an iSCSI capable intermediate device that deploys prefetching strategies in combination with redundant disks to reduce average I/O-latency. Depending on its location within the network, this virtualization and prefetching device can hide wide area access latency and reduce network contention targeting remote SCSI-devices to a large extent.

This implies the appliance of service level agreements to guarantee a negotiated level of quality of service. These requirements also affect the local resource management systems providing resources for the Grid. At this a gap between these demands and the features of today's resource management systems becomes apparent. In this paper we present an approach which closes this gap. Introducing the architecture of the virtual resource manager we highlight its main features of runtime responsibility, resource virtualization, information hiding, autonomy provision, and smooth integration of existing resource management system installations.

Diffusion controlled cluster–cluster aggregation is assumed to be the prevailing coagulation mechanism which is implemented using a Monte–Carlo algorithm. Sintering is modeled as a successive overlapping of spherical primary particles, which are allowed to grow as to preserve overall mass. Simulations are characterized by individual ratios τ of characteristic collision to fusion time. A number of resulting aggregate-structures is displayed and reveals structure formation by coagulation and sintering for different values of τ. These aggregates are described qualitatively and quantitatively by their mass fractal dimension Df and radius of gyration. The fractal dimension increases from 1.86 for pure aggregation to ≈ 2.75 for equal characteristic time scales. As sintering turns out to be more and more relevant, increasingly compact aggregates start to form and the radius of gyration decreases significantly. The simulation results clearly reveal a strong dependence of the fractal dimension on the kinetics of the concurrent coagulation and sintering processes. Considering appropriate values of Df in aerosol process simulations may therefore be important in many cases.

Major components are a hot-wall tubular reactor for the production of unsintered aggregates consisting of spherical primary particles in the size range 10–80 nm and a sintering reactor for the investigation of the sintering kinetics at well-defined temperature and residence time history. Therefore, rapid heating and quenching of the particles at the beginning and at the end of the reaction zone, respectively, is maintained. Main parameters in the sintering reactor are: temperatures up to 1873 K and residence times in the range 8–1000 ms. The reactor conditions are characterized by temperature profile measurements with a newly constructed suction thermocouple probe and by computational fluid dynamics simulations of the residence time distributions. Exemplary results of the sintering of silica nanoparticles obtained by transmission electron microscopy analysis are presented. AU - Kirchhof, Martin J.

The reason for the high costs results mainly from the fact that analyses are often made manually or with automatic tool support, which is inappropriate for analyzing large systems. Semi-automatic analysis approaches usually use a notion of fuzziness to overcome this limitation, but inherit the problem of selecting appropriate initial values. In this paper we present an approach to adapt the initial values of our semi-automatic reverse engineering process. We provide the reverse engineer with accuracy information for results produced by a rule-based inference algorithm. Based on the changes of the results done by the reverse engineer we automatically adapt a credibility value of each rule, which previously has been used to compute the accuracy of the result. The adaption fits seamlessly into our overall analysis process. First tests show that it is suitable for the calibration of our fuzzyfied rule-based pattern recognition approach.

Our results are parametrized by the variance of the noise distribution. For large variance we essentially consider the average case for distribution Δ while for variance 0 we consider the worst case. Hence our results give upper bounds on the number of extreme points where our input distributions range from average case to worst case.
Our main contribution is a rather general lemma that can be used to obtain upper bounds on the expected number of extreme points for a large class of noise distributions. We then apply this lemma to obtain explicit bounds for random noise coming from the Gaussian normal distribution of variance σ² and the uniform distribution in a hypercube of side length &epsilon. For these noise distributions we show upper bounds of O( (1/ σ )^d * log^3/2 * d - 1 n ) and O( ( (n log n) / ε )^d/(d+1) ), respectively. Besides its theoretical motivation our model is also motivated by the observation that in many applications of convex hull algorithms the input data is inherently noisy, e.g. when the data comes from physical measurement or imprecise arithmetic is used.

We propose to include a small buffer between appli- cation and graphics hardware in the rendering sys- tem. This pipeline buffer is used to rearrange the incoming sequence of primitives on-line and locally in such a way that the number of state changes is minimized. This method is generic; it can be easily integrated into existing rendering systems. In our experiments a pipeline buffer reduces the number of state changes by an order of magnitude and achieves almost the same rendering time as an optimal, i.e., presorted, sequence without pipeline buffer. Due to its simple structure and its low mem- ory requirements this method can easily be imple- mented in software or even hardware.
