Focusing on the complexities of monitoring large cluster computers, this book categorizes the often ambiguous concept of "monitoring" in this context. It introduces a scalable monitoring solution tailored for clusters utilizing InfiniBand networks and includes in-depth analyses of monitoring's effects on computing performance. The research utilizes the Nagios monitoring suite to assess CPU and network impacts and offers strategies for minimizing interference with essential computations. Targeted at professionals and researchers, it addresses crucial management and monitoring challenges in high-performance computing environments.

In the quest for better differentiation of their products, many firms in B2B markets have started to systematically invest in brand building. Stefan Worm analyzes how component supplier brand strength among original equipment manufacturers’ (OEMs’) customers affects component suppliers’ market performance in their relationships with these OEMs. Further, the author determines which management instruments are effective in building, sustaining, and leveraging component supplier brand strength. The analysis relies on data collected from multiple manufacturing industries.

To monitor the state of a cluster computer with hundreds of computing nodes is not as simple as monitoring the state of one's personal computer at home. Especially when handling such valuable systems where essential computations for scientific or important business purposes are being executed, it is essential to be up-to-date about the systems functions. This book presents a classification of the wide and vaguely used term -monitoring- for computer clusters. In addition to that a solution is developed to perform scaleable monitoring of clusters with an InfiniBand network interconnection. Therefore, extensive analyses to determine the real impact of the monitoring on the computing performance of the cluster are presented, for which partially the monitoring suite Nagios is used. The book is directed to professionals, researchers and other persons, that have to deal with the management and monitoring of an InfiniBand network, as well as with the issue how much the monitoring process influences computations of the cluster (CPU and network impact) and how to minimize this."
