Efficient and robust metacomputing requires the decomposition of complex jobs into tasks that must be scheduled on distributed processing nodes. There are various ways of creating...
Abstract This paper proposes an approach to continuously optimizing parallel scientific applications with dynamically changing architectures. We achieve this by combining a dynamic...
Abstract—The throughput of multi-hop communication systems can significantly be increased by the application of MIMO concepts. To utilize the physical resources in an efficient...
— Organizations use security policies to regulate how they share and exchange information, e.g., under what conditions data can be exchanged, what protocols are to be used, who i...
In conventional security systems, protected resources such as documents, hardware devices and software applications follow an On/Off access policy. On, allows to grant access and ...
