Current multicore system technology enables implementation of particular program functions like library operations, special functions generation, optimized data search etc. using dedicated computing units to increase overall program performance. A parallel system can be equipped with a set of such units to speed up execution of applications, which use such functionality. To properly model and schedule programs using such functions running on a dedicated hardware, a proper program representation must be introduced. the paper presents special scheduling algorithm for programs represented as graphs, based on a modified ETF heuristics. the algorithm is meant for a modular architecture composed of many CMP modules interconnected by a global data communication network. the assumed architecture of dedicated CMP modules enables personalized fully synchronous program execution, which uses communication on the fly to strongly reduce inter-core communication overheads.
Key generation, a well known alternative to key distribution, allows two (or more) parties to concurrently generate the same secret key through their independent measurements of a mutually observable random informatio...

CoreGRID is a European research network of Excellence (NoE) that was initiated in 2004 as part of the EU FP6 research framework and run up to 2008. CoreGRID partners, from 44 different countries, developed theoretical foundations and software infrastructures for large-scale, distributed Grid and P2P applications. An ERCIM sponsored CoreGRID Working Group was established to ensure the continuity of the CoreGrid programme after the official end of NoE. the working group extended its interests to include the emerging field of (service based) cloud computing which is of great importance to the European software industry. Its main goals consist in i) sustaining the operation of the CoreGRID network, ii) establishing a forum to encourage collaboration between the Grid and P2P computing research communities, and (iii) encourage research on the role of cloud computing as a new paradigm for distributed computing in e-Science.

Constructing a scientific and effective bank risk forewarning model is an important measure to effectively guard against and defuse risks in commercial banks. this article constructs a bank risk forewarning model using BP neural network and principal component analysis method. Meanwhile, being aimed at that it takes a long time while processing the mass data to train the network, it also decomposes the algorithm for MapReduce, running in parallel to reduce the running time. the experiment result shows that the neural network model achieved higher accuracy of rate 88percents.

this paper presents a novel approach to the study of heterogeneous networks. NetBoxIT is a modular, and scalable testbed based on virtualized network emulators. these can be interconnected and run in parallel to reproduce complex networks scenarios within a shared, multi-core hardware platform. We examine the testbed performance with simple emulation trials (related to the reference Emergency network under study within the EU 7th FP project "A holistic approach towards the development of the first responder of the future"), to verify its realism in assessing multipart networks evaluations.

In this paper we describe the implementation of a declarative framework to support the development of distributed management applications. the framework is based on an extension of declarative networking, an asynchronous computational model that uses recursive SQL as its foundation and has been successfully used for the implementation of multiple networking protocols including opinion-based preferential routing as well as standard path vector and link state routing protocols. the SQL implementation enables analysis capabilities that can help avoid implementation and logic errors.
