Targeting Distributed Systems in FastFlow

FastFlow is a structured parallel programming framework targeting shared memory multi-core architectures. In this paper we introduce a FastFlow extension aimed at supporting also a network of multicore workstations. The extension supports the execution of FastFlow programs by coordinating–in a structured way–the fine grain parallel activities running on a single workstation. We discuss the desi...

Synaptic Adhesion: the Building Blocks of Memory?

five cadherin repeats of ‫011ف‬ amino acids (Figure 1). The cadherin repeat most distal from the single trans-membrane domain, termed EC1, is thought to mediate the principal adhesion between cadherin molecules (Nose et al., 1990). The other important region is the intracellular domain, which assumes a regulatory role. It is responsible for coordination to the cytoskeleton—via two linker protei...

A Distributed Memory Algorithm for Lexicon Building

A parallel algorithm for preparing word frequency concordances over two speci ed sets of documents from a collection is presented. Good parallel e ciency is demonstrated on a 128-node distributed memory machine using sets whose combined size exceeds one gigabyte. It is demonstrated that e ciency is heavily in uenced by hashing and communication strategies. A two-stage hashing algorithm is propo...

Organizational building blocks for design of distributed intelligent system

In this work we present a framework for multi-agent system design which is based both on human organizational notions and principles for distributed intelligent systems design. The framework elaborates on the idea that notions from the field of organizational design can be used as the basis for the design of distributed intelligent systems. Concepts such as task, control, job, operation, manage...
