TL;DR: This paper proposes a performance-driven design of an HPC IaaS layer for InfiniBand, which provides throughput and latency-aware virtualization of nodes, networks, and network topologies, as well as an approach to a HPC-aware, multi-tenant cloud management system for elastic virtualized HPC compute clusters.
Abstract: High Performance Computing (HPC) employs fast interconnect technologies to provide low communication and synchronization latencies for tightly coupled parallel compute jobs. Contemporary HPC clusters have a fixed capacity and static runtime environments; they cannot elastically adapt to dynamic workloads, and provide a limited selection of applications, libraries, and system software. In contrast, a cloud model for HPC clusters promises more flexibility, as it provides elastic virtual clusters to be available on-demand. This is not possible with physically owned clusters.In this paper, we present an approach that makes it possible to use InfiniBand clusters for HPC cloud computing. We propose a performance-driven design of an HPC IaaS layer for InfiniBand, which provides throughput and latency-aware virtualization of nodes, networks, and network topologies, as well as an approach to an HPC-aware, multi-tenant cloud management system for elastic virtualized HPC compute clusters.

TL;DR: The design of a better management solution - the KOALA cloud management service - for cloud services and its implementation are described.
Abstract: The key advantages of cloud computing are flexibility, scalability (elasticity) and usability and these features originate in the combination of virtualization technologies with web services. However, in contrast to the elasticity and flexibility of cloud services the traditional management methods and tools seem inappropriate because they usually require local software installation with continuous updates and patches. Furthermore, the solutions are often proprietary and only conform to the cloud service offerings of specific service providers, making it difficult to work with cloud services of different providers. A vendor agnostic generic cloud based software service would bear many advantages in this area. This paper describes the design of a better management solution - the KOALA cloud management service - for cloud services and its implementation.

TL;DR: An overview of the HappyFace architecture and selected modules is given, which offers elegant mechanisms to collect, process and evaluate all relevant information and to condense it into a simple rating visualisation, reflecting the current status of a computing centre.
Abstract: An efficient administration of computing centres requires sophisticated tools for the monitoring of the local computing infrastructure. The enormous flood of information from different monitoring sources retards the identification of problems and complicates the local administration unnecessarily. The meta-monitoring system "HappyFace" offers elegant mechanisms to collect, process and evaluate all relevant information and to condense it into a simple rating visualisation, reflecting the current status of a computing centre. In this paper, we give an overview of the HappyFace architecture and selected modules.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: The findings indicate that extant cloud computing literature tends to skew towards the technological dimension to the detriment of other under researched dimensions such as business, conceptualization and application domain.
