We have built clusters of PC using up to 320 processors in parallel. The first cluster was built in 1996 from 64 computers. The parallel architectures are named RAMSES. In this article, we share our experience and discuss our choices. The architecture is composed of Pentium processors connected by a 100 Mbits/s Ethernet network. Because RAMSES are built of independent computers, the system is easily maintained, and can be modified by adding or removing machines. Two programs, which are dedicated to molecular modeling and were previously developed on single machines (OSIRIS and IMPALA), have been adapted. IMPALA models peptide and protein interaction with membranes, OSIRIS simulates an ab initio folding of globular proteins. After parallelization, each program consists of two parts: one is the human/RAMSES interface, and the second is the simulation per se. The parallel architecture is transparent for the users. Tests of the IMPALA and OSIRIS efficiencies are shown and discussed. [less ▲]

WASP is a programmable router platform that allows end-hosts to store ephemeral state in routers along the path of IP flows and to execute packet-attached bytecode that processes this data. We exploit lessons from past active network research and our knowledge of network processors to design a minimal interpreter that favours language restrictions over run-time checks. WASP provides safety with limited performance penalty through predictable execution time and bounded usage of memory and network resources. WASP is expressive enough to enable several applications including statistics collection and service discovery. It can also detect common trunk of two Internet paths and exchange local measurements about these paths. We propose a robust implementation on the IXP2400 network processor, and evaluate its performance through short benchmark programs against native functions hard-coded in the router. We achieve latencies below 7$\,\mu{s}$, i.e. less than the reference IPv4 forwarding latency, and throughputs approaching 800\,kpps per core, which competes with, and sometimes even outperforms, native programs. We further exploit our results to give hints on further improving resource usage and guidelines on management of ephemeral stores in high-speed networks. [less ▲]

The concept of nonlinear normal modes (NNMs) is considered in the present paper. One reason of the still limited use of NNMs in structural dynamics is that their computation is often regarded as impractical. However, when resorting to numerical algorithms, we show that the NNM computation is possible with limited implementation effort, which paves the way to a practical method for determining the NNMs of nonlinear mechanical systems. The proposed algorithm relies on two main techniques, namely a shooting procedure and a method for the continuation of NNM motions. The algorithm is demonstrated using two different mechanical systems, a nonlinear two-degree-of-freedom system and a nonlinear cantilever beam discretized by the finite element method. [less ▲]

The aim of the paper is to develop a new nonlinear tuned vibration absorber (NLTVA) capable of mitigating the vibrations of nonlinear systems which are known to exhibit frequency-energy-dependent oscillations. A nonlinear generalization of Den Hartog’s equal-peak method is proposed to ensure equal peaks in the nonlinear frequency response for a large range of forcing amplitudes. An analytical tuning procedure is developed and provides the load-deflection characteristic of the NLTVA. Based on this prescribed relation, the NLTVA design is performed by two different approaches, namely thanks to (i) analytical formulas of uniform cantilever and doubly-clamped beams and (ii) numerical shape optimization of beams with varying width and thickness. A primary system composed of a cantilever beam with a geometrically nonlinear component at its free end serves to illustrate the proposed methodology. [less ▲]

LaTeX is a beautiful programming language. One sometimes wants to write in an easy and quick way various documents, such as letters, papers, reports, theses, and so on. Here, “one” can be a new student, an old professor, or even somebody who is not linked at all with any academic stuff. We often want special constructs in our documents. This is more difficult than basic typesetting, especially using LaTeX when you are not experienced. On one hand, scientists do not always have the time to learn another programming language, especially if they are making a PhD, or doing something else which asks for a lot of time. Using direct and working programming tricks can speed up your productivity, and make you learning better. But where can they be found? On the other hand, everybody wants to make nice documents, if possible. A nicer document attracts the reader. Evidently, “a nice document” is a subjective notion. By “nice document,” we want to speak about a document which 1. is structured in an unambiguous way, and has a clear presentation, 2. is read with pleasure, if possible. The beginner, whoever he is, often faces strange errors because he tries to teach LaTeX to do what he wants it to do. It is difficult to learn the advanced notions about LaTeX, even in an average period of time. The good books have to be found. But that is often the moment where you lack of time and that you are happy to find complete solutions. That is a moment where you tell to yourself “Is there no folk out there to give me such a trivial tip?” but nobody hears it. The aim of this book, is to avoid you these problems: you do not need to write everything from scratch, ask on various forums or Usenet groups, or even read heaps of books just to make a simple script. That is my goal. You can now continue writing your document in LaTeX’s philosophy: concentrating on your document’s content, at the place of its appearence. These reasons justify the presence of this book. I have tried to pack the most useful tricks which can enhance your documents’ content in a concise way. The aim is not to teach LaTeX programming, but to give a quick reference to all the tips and tricks that can be used if you are encountering a (difficult) problem, or simply facing a question which you cannot find the answer to. I consider that the reader is familiar with basic LATEX programming. It can be learnt from various sources (given in this book's bibliography), and many others. I hope this will give you new ideas about advanced ways to typeset text and to make different processes automatic, thus giving you more time for other activities. Many others subjects were added during Fall 2010. [less ▲]
