SZTAKI Desktop Grid (SZDG) is an extension of BOINC in order to make it more flexible, versatile and scalable in terms of enabling the interconnection of different BOINC projects and execution of parameter sweep applications from a generic, high level user interface without the intervention of the BOINC project administrator. The paper describes the main(More)
Desktop Grids harvest the computing power of idle desktop computers whether these are volunteer or deployed at an institution. Allowing foreign applications to run on these resources requires the sender of the application to be trusted, but trust in goodwill is never enough. An efficient solution is to provide a secure isolated execution environment(More)
So far BOINC based desktop grid systems have been applied at the global computing level. This paper describes an extended version of BOINC called SZTAKI desktop grid (SZDG) that aims at using desktop grids (DGs) at local (enterprise/institution) level. The novelty of SZDG is that it enables the hierarchical organisation of local DGs, i.e., clients of a DG(More)
The Desktop Grid model harvests unused CPU cycles of connected computers. In this report we present a concept how separate Desktop Grids can be used as building blocks for larger scale grids by organizing them in a hierarchical tree. We present a prototype implementation and show the challenges and security considerations we discovered. We describe methods(More)
Desktop Grids, such as XtremWeb and BOINC, and Service Grids, such as EGEE, are two different approaches for science communities to gather computing power from a large number of computing resources. Nevertheless, little work has been done to combine these two Grid technologies in order to establish a seamless and vast Grid resource pool. In this paper we(More)
Desktop Grids represent an alternative trend in Grid computing using the same software infrastructure as Volunteer Computing projects, such as BOINC. Applications to be deployed on a BOINC infrastructure need special preparations. However, there are many legacy applications, that have either no source code available or would require too much effort to port.(More)
Service Grids like the EGEE Grid can not provide the required number of resources for many VOs. Therefore extending the capacity of these VOs with volunteer or institutional desktop Grids would significantly increase the number of accessible computing resources that can particularly advantageously be exploited in case of parameter sweep applications. This(More)
Service grids and desktop grids are both promoted by their supportive communities as great solutions for solving the available compute power problem and helping to balance loads across network systems. Little work, however, has been undertaken to blend these two technologies together. In this paper we introduce a new EU project, that is building(More)
Cloud Computing enables the construction and the provisioning of virtualized service-based applications in a simple and cost effective outsourcing to dynamic service environments. Cloud Federations envisage a distributed, heterogeneous environment consisting of various cloud infrastructures by aggregating different IaaS provider capabilities coming from(More)
The paper completes the work started in the EU FP7 EDGI project for extending service grids with volunteer (global) and institutional (local) desktop grids. The Generic BOINC Application Client (GBAC) concept described in the paper enables the transparent and automatic forwarding of parameter sweep application (parametric) jobs from service grid VOs(More)
