Secure Integration of Desktop Grids and Compute Clusters Based on Virtualization and Meta-Scheduling
Reducing the cost for business or scientific computations, is a commonly expressed goal in today’s companies. Using the available computers of local employees or the outsourcing of such computations are two obvious solutions to save money for additional hardware. Both possibilities exhibit security related disadvantages, since the deployed software and data can be copied or tampered if appropriate countermeasures are not taken. In this paper, an approach is presented to let a local desktop machines and remote cluster resources be securely combined into a singel Grid environment. Solutions to several problems in the areas of secure virtual networks, meta-scheduling and accessing cluster schedulers from desktop Grids are proposed

Leveraging simulation practice in industry through use of desktop grid middleware
This chapter focuses on the collaborative use of computing resources to support decision making in industry. Through the use of middleware for desktop grid computing, the idle CPU cycles available on existing computing resources can be harvested and used for speeding-up the execution of applications that have “non-trivial” processing requirements. This chapter focuses on the desktop grid middleware BOINC and Condor, and discusses the integration of commercial simulation software together with free-to-download grid middleware so as to offer competitive advantage to organizations that opt for this technology. It is expected that the low-intervention integration approach presented in this chapter (meaning no changes to source code required) will appeal to both simulation practitioners (as simulations can be executed faster, which in turn would mean that more replications and optimization is possible in the same amount of time) and the management (as it can potentially increase the return on investment on existing resources)
HEP@Home - A distributed computing system based on BOINC
Project SETI@HOME has proven to be one of the biggest successes of
distributed computing during the last years. With a quite simple approach SETI
manages to process large volumes of data using a vast amount of distributed
computer power.
To extend the generic usage of this kind of distributed computing tools,
BOINC is being developed. In this paper we propose HEP@HOME, a BOINC version
tailored to the specific requirements of the High Energy Physics (HEP)
community.
The HEP@HOME will be able to process large amounts of data using virtually
unlimited computing power, as BOINC does, and it should be able to work
according to HEP specifications. In HEP the amounts of data to be analyzed or
reconstructed are of central importance. Therefore, one of the design
principles of this tool is to avoid data transfer. This will allow scientists
to run their analysis applications and taking advantage of a large number of
CPUs. This tool also satisfies other important requirements in HEP, namely,
security, fault-tolerance and monitoring.Comment: 4 pages, 4 Postscript figures, uses CHEP2004.cls, submitted to

HIL: designing an exokernel for the data center
We propose a new Exokernel-like layer to allow mutually untrusting physically deployed services to efficiently share the resources of a data center. We believe that such a layer offers not only efficiency gains, but may also enable new economic models, new applications, and new security-sensitive uses. A prototype (currently in active use) demonstrates that the proposed layer is viable, and can support a variety of existing provisioning tools and use cases.Partial support for this work was provided by the MassTech Collaborative Research Matching Grant Program, National Science Foundation awards 1347525 and 1149232 as well as the several commercial partners of the Massachusetts Open Cloud who may be found at http://www.massopencloud.or
