This paper is intended to help instructors in universities without supercomputer facilities to teach a senior- or graduate-level course on parallel processing. It outlines how supercomputing centers can be accessed, how simulation packages can be obtained, how the course and its laboratory can be organized, and recommends a set of projects, textbooks, and articles that could be used in the course.

Research for which the idea that many basic cognitive processes can be described as fast, parallel, and automatic is reviewed. Memory retrieval/decision processes have often been ignored in the cognitive literature. However, in some cases, computationally complex processes can be replaced with simple passive processes. Cue-dependent retrieval from memory provides a straightforward example of how encoding, memory, and retrieval can interact. Three other examples are reviewed: inference in text processing, compound cue models for priming, and implicit memory. In each case, the research benefits from a focus on retrieval and decision processes. For implicit memory, consideration of these kinds of processes leads to a view of implicit memory different than hypothesizing new specialized memory systems. Finally, how behavioral data from simple decisions and the models that explain the behavior can be related to neuroscience research on neural firing rates are discussed.

A novel clinical and experimental situation has been created, based on the psychopathological concepts of 'pensée opératoire' and alexithymia and the contribution of recent trends in cognitive science as to the dual skills of the brain hemispheres: the Parallel Visual Information Processing Test. This test was validated in more than 100 subjects, and revealed that holistic visual attention is reduced during logical task performance; this impairment appeared to be typical of patients with poor fantasizing ability and operative behavior. Such findings are consistent with some authors' theory according to which there is a functional commissurotomy in alexithymic and psychosomatic patients.

In this work, we adopt a statistical-mechanics approach to investigate basic, systemic features exhibited by adaptive immune systems. The lymphocyte network made by B cells and T cells is modeled by a bipartite spin glass, where, following biological prescriptions, links connecting B cells and T cells are sparse. Interestingly, the dilution performed on links is shown to make the system able to orchestrate parallel strategies to fight several pathogens at the same time; this multitasking capability constitutes a remarkable, key property of immune systems as multiple antigens are always present within the host. We also define the stochastic process ruling the temporal evolution of lymphocyte activity and show its relaxation toward an equilibrium measure allowing statistical-mechanics investigations. Analytical results are compared with Monte Carlo simulations and signal-to-noise outcomes showing overall excellent agreement. Finally, within our model, a rationale for the experimentally well-evidenced correlation between lymphocytosis and autoimmunity is achieved; this sheds further light on the systemic features exhibited by immune networks.

This thesis presents a new architecture for a parallel multiplier. For large words, both multiplication time and area required are large when conventional methods are used. In this thesis, an architecture is discussed to multiply large words by means of overlapped multi-bit scanning. This technique can be applied, without significant change in the conventional architecture, to achieve great improvement in overall performance. New multiplier architectures with a minimum time area product can be detected using the method discussed for a CSA tree. An efficient technique is presented to generate negative multiples of multiplicands required in most of

We designed, implemented, and evaluated a signal-processing environment that runs on a general-purpose multiprocessor system, allowing easy prototyping of new algorithms and integration with applications. The environment allows the composition of modules implementing individual signal-processing algorithms into a functional application, automatically optimizing their performance. We decompose the problem into four independent components: signal processing, data management, scheduling, and control. This simplifies the programming interface and facilitates transparent parallel signalprocessing. For tested applications, our system both runs efficiently on single-processors systems and achieves near-linear speedups on symmetric-multiprocessor (SMP) systems. Thesis Supervisor: John V.

CumuloNimbo aims at solving the lack of scalability of transactional applications that represent a large fraction of existing applications. CumuloNimbo aims at conceiving, architecting and developing a transactional, coherent, elastic and ultra scalable Platform as a Service. Its goals are: Ultra scalable and dependable, able to scale from a few users to many millions of users while at the same time providing continuous availability; Support transparent migration of multi-tier applications (e.g. Java EE applications, relational DB applications, etc.) to the cloud with automatic scalability and elasticity. Avoid reprogramming of applications and non-transparent scalability techniques such as sharding. Support transactions for new data stores such as cloud data stores, graph databases, etc.The main challenges are: Update ultrascalability (million update transactions per second and as many read-only transactions as needed). Strong transactional consistency. Non-intrusive elasticity. Inexpensive high availability. Low latency. CumuloNimbo goes beyond the state of the art by scaling transparently transactional applications to very large rates without sharding, the current practice in Today?s cloud. In this paper we describe CumuloNimbo architecture and its performance.
