Distributed

La fin est magnifique. Un chef d'oeuvre a conseiller aux enfants

This is an average book. But I liked the Distributed Algorithms by Nancy Lynch better. It is a much better presented book that this one though most of the material covered is the same give or take a few. Over all a good book worth the money but there are better books.

Sample files are missing. Get to Coriolis wed site to download the patch. The book talks a lot about client server data base application. Lack of coverage on different member functions that makes Power++ powerful.

I am a Ph.D Candidate, majored in Multimedia Communication. This book provides the reader with some very important principles and fundamental knowledge about the design of distribuited multimedia systems. It is a good book for the researchers and graduate students majored in multimedia communication architecture. You must have enough knowledge about CORBA, DCE, ODP and multimedia communication. If you just want to get some general knowledge about ODP, do not read it.

i had a project in implementing and designing a load balancing manager used by content serving companies. Well i had that project and believe me this book helped me

This book is subtitled as "An all-inclusive survey of the fundamentals of parallel and distributed computing." It both succeeds and fails on this point. Leopold does indeed cover a wide expanse of technologies and approaches that characterize the space of high performance computing. It is in many ways still an emerging space, so conclusively nailing down every possible thread (no pun intended) in a coherent fashion is eminently difficult. The author's treatment of these different possibilities is uneven, overlooking some important contemporary technologies and implementations. It does cover a wide range of topics within the fields of distributed and parallel computing. Furthermore, within the chapters Leopold treats us to both high-level discussions of approaches and provides a glimpse into some of the implementation challenges involved. On the latter point especially, this book is very useful in that it gives the noninitiate some understanding and appreciation of the peculiarities of parallel programming, without requiring substantial technical background in the technologies. The examples in High Performance C and Parallel Fortran were very enlightening.

Where the book fails is that it is far from "all inclusive". There are a number of prominent and important developments that have not been included. Similarly, there are other interesting newer technologies that have only received cursory treatment. Examples include:

- No mention of SETI@Home. SETI@Home is the poster child of massively distributed computing, and with 15 teraflops of raw computing power, it is more capable than IBM's ASCI White supercomputer.
- No mention of distributed.net, or other notable exercises in public and commercial grid computing.
- Grid computing gets only a glancing reference at the tail end of one chapter. A comparative analysis of this important and still-forming space is glaringly absent from this text.
- JavaSpaces, Sun's answer to tuple-spaces, gets only a few sentences.
- Java RMI similarly gets less than a paragraph.
- Although DCOM is now basically legacy for Microsoft, it represents an important milestone in the evolution of distributed computing. It receives only a paragraph.
- Talk of web services and .Net would have been hitting the airwaves as the writing of this book as progressing, although possibly late in the effort. However, some cursory mention at least should have been made. There is increasing discussion of exposing grid compute services via web services interfaces, and Microsoft has recently announced their intention to port the Globus toolkit to Windows.
- Oh yeah, about Globus. Barely a mention.

It was clear from the text that the author came from a strong UNIX and CORBA background. The text has the feel of a PhD thesis-turned-book, and the areas of concentration are decidedly academic. There are a few other areas of minor complaint. Some of the wording in the text is clumsy, reflecting inadequate editing. Some topics feel like they are introduced in reverse order, assuming the reader already has some context about the given topic.

The author makes a sometimes-clumsy distinction between paradigms and models. The distinction is important in that an understanding of models brings a reader closer to envisioning how they might tackle a given problem themselves. However, reference to various models are sprinkled throughout the book. A comparative analysis, even brief, would have been very useful had it been centralized.

Those complaints may sound harsh, but overall the book is useful. It demystifies the problems of parallel programming, and provides a reasonably concise starting point for researching the distributed computing space. But, consider this book a starting point, and not an ending point.

The book covers old material in that it is based on Ada83, but then it is an old book. There is good information on the considerations involved in writing an operating system. I was disappointed that they still used C for the kernel, but the explanation of the kernel writing was an interesting read. Appendix C was a good review of Ada tasking. I need to read it again more carefully, and then brush up on Ada95 tasking to see if the problems mentioned would still be a problem with Ada95. The other problems they encountered with using Ada (not having a real compiler and having to use a cross compiler) wouldn't be applicable today. The research they did was for distributed systems and there is a lot of information about distributed processing that is still relevent today. Generally, it is a nice read.

Dear Editor, The book doesn't include the effect of failure widly.

'Salo' is a prominent in that select group of 'scandalous' 1970s films (e.g. 'Straw Dogs', 'In the Realm of the Senses') which retains the power to shock, appal, unnerve today (although I personally found 'Salo' more numbing that anything). Pasolini's last film before his brutal murder in 1975, it is a transplanting of the Marquis de Sade's infamous 1785 novel to the dying days of Fascist Italy, in which four prominent figures (a bishop, an aristocrat, a banker and a judge) retire to an abandoned villa with soldiers, courtesans, collaborators and 18 slaves to indulge in a ritualised orgy of sexual excess, faecal banquets, storytelling, torture and murder.

Gary Indiana's monograph starts well, with a number of apparent digressions effectively contextualising 'Salo': the author's first encounter with the film in the ... L.A. of the 1970s; 'Salo''s place at the culmination of Pasolini's career (with a clear-eyed appraisal of that career, and the personal and political biography that was inseperable from it); 'Salo''s status as the last major art-movie, released in the same year as 'Jaws' destroyed auteurism, independence and experiment forever (a development Indiana bracingly rants against).

Indiana is very good on Pasolini's contradictions, his courage and frequent dislikability, his style of 'contamination' (e.g. interspersing 'real' actors in a predominantly unprofessional cast; his recourse to pastiche and allusion) and some of his major themes - the lingering fascism in the soulless corruption of consumerist society and its debasing of the human body; the superiority of pre-industrial rusticity etc.

But when he gets to the film itself, Indiana opts for a lengthy description of its plot with occasional asides. As so often in this series (and the BFI classics), the lack of systematic criticism (from non-film-academic/critics)leads to a frustratingly bitty stu.

It is not a bad book for the person with no Informix background It is a good book for knowing the basis facts about the informix dbase. However, it does not explain completely full integration concepts between SAP and informix to sap administrator.
