[pro] GPU/CUDA & common lisp
by Tamas Papp 05 Apr '12

05 Apr '12

Hi everyone, I am about to buy a new server for number crunching, and I would like to keep my options open about GPU/CUDA based computations. The most intensively parallelizable thing that I am doing is particle filtering, and currently that works fine (and is really fast) in a multi-core CPU with SBCL, but I keep hearing wonderful things about GPUs from people, and I was wondering if I could make use of them but still program in CL. I basically have two questions: - What is the current status of using CPUs for computation in CL (in particular SBCL)? All I found was CL-GPU but I haven't tried it yet (my current server does not have a GPU). - What hardware is supported (if I want to use CL)? Can I use something like Nvidia's TESCLA C line? Any help/pointers/accounts would be appreciated, I am just exploring this so I don't know much about it yet, apologies if I am not asking the right questions. Best, Tamas

[pro] [ELS 2012] European Lisp Symposium 2012, Zadar, Croatia; call for papers
by Marco Antoniotti 17 Nov '11

17 Nov '11

Apologies for the multiple postings.... ================================================================ European Lisp Symposium 2012, Zadar, Croatia, April 30th - May 1st, 2012 http://european-lisp-symposium.org The purpose of the European Lisp Symposium is to provide a forum for the discussion and dissemination of all aspects of design, implementation and application of any of the Lisp and Lisp-inspired dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, Dylan, Clojure, ACL2, ECMAScript, Racket, SKILL, and so on. We encourage everyone interested in Lisp to participate. The main theme of the 2012 European Lisp Conference is "Interoperabilty: Systems, Libraries, Workflows". Lisp based and functional-languages based systems have grown a variety of solutions to become more and more integrated with the wider world of Information and Communication Technologies in current use. There are several dimensions to the scope of the solutions proposed, ranging from "embedding" of interpreters in C-based systems, to the development of abstractions levels that facilitate the expression of complex context dependent tasks, to the construction of exchange formats handling libraries, to the construction of theorem-provers for the "Semantic Web". The European Lisp Symposium 2012 solicits the submission of papers with this specific theme in mind, alongside the more traditional tracks which have appeared in the past editions. We invite submissions in the following forms: Papers: Technical papers of up to 15 pages that describe original results or explain known ideas in new and elegant ways. Demonstrations: Abstracts of up to 4 pages for demonstrations of tools, libraries, and applications. Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest for at least 90 minutes and up to 180 minutes. Lightning talks: Abstracts of up to one page for talks to last for no more than 5 minutes. All submissions should be formatted following the ACM SIGS guidelines and include ACM classification categories and terms. For more information on the submission guidelines and the ACM keywords, see: http://www.acm.org/sigs/publications/proceedings-templates and http://www.acm.org/about/class/1998. Important dates: Jan 31st 2012: submission deadline Feb 21st 2012: acceptance results April 30th, 2012 Conference opens Program Commitee. Chair: Marco Antoniotti, Università degli Studi di Milano Bicocca, Milan, ITALY Local organizers: • Damir Ćavar, Eastern Michigan University • Franjo Pehar, University of Zadar • Damir Kero, University of Zadar Members: • Giuseppe Attardi, Università degli Studi di Pisa, Pisa, ITALY • Pascal Costanza, Intel, Bruxelles, BELGIUM • Marc Feeley, Université de Montreal, Montreal, CANADA • Scott McKay, Google, U.S.A. • Kent Pitman, Hypermeta, U.S.A. • Christophe Rhodes, Department of Computing, Goldsmiths, University of London, London, UNITED KINGDOM • Robert Strandh, LABRI, Université de Bordeaux, Bordaux, FRANCE • Didier Verna, EPITA / LRDE, FRANCE -- Marco Antoniotti

[pro] [Review Request] Small example of modern application of Common Lisp
by Christian von Essen 02 Nov '11

02 Nov '11

Hi, I use CL to scrape several comic websites and generate a website that collects the daily strips from that. The (small) program's features: * Easy definition of comic sources * Uses xpath to get the comics * Stores an archive of daily comics * Generate web pages with comics per day A feature that is IMHO still missing is easier (maybe interactive) comic specification. Currently you better get your xpath right. I think it would be possible to promote CL with an application like that. Could you have a look at the code and give me some hints on style and CL in general, so that the code actually becomes good enough for that purpose? You can find it there: https://github.com/Neronus/Lisp-Utils/blob/master/comics.lisp And an example of the generated output here: http://christian.ftwca.de/comics/ Thank you, Christian
