~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 4th European Lisp Symposium Special Focus on Parallelism & Efficiency March 31 - April 1st, 2011 TUHH, Hamburg University of Technology Hamburg, Germany http://www.european-lisp-symposium.org/ Sponsored by EPITA, Lispworks, Franz Inc. and Nova Sparks ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Invited Speakers: ~~~~~~~~~~~~~~~~~ Marc Battyani (Nova Sparks) Craig Zilles (University of Illinois) Important Dates ~~~~~~~~~~~~~~~~ + Submission Deadline: January 09, 2011 + Author Notification: February 06, 2011 + Final Paper Due: February 28, 2011 + Symposium: March 31 - April 1st, 2011 Authors of accepted research contributions will be invited to submit an extended version of their papers for journal publication. Scope ~~~~~~ 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 dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, Dylan, Clojure, ACL2, ECMAScript, Racket and so on. We encourage everyone interested in Lisp to participate. The European Lisp Symposium 2011 invites high quality papers about novel research results, insights and lessons learned from practical applications, and educational perspectives. We also encourage submissions about known ideas as long as they are presented in a new setting and/or in a highly elegant way. This year's focus will be directed towards "Parallelism & Efficiency". We especially invite submissions in the following areas: + Parallel and distributed computing + Code generation for multi-core architectures + Code generation for HTM + Large and ultra-large systems + Optimization techniques + Embedded applications Contributions are also welcome in other areas, including but not limited to: + Context-, aspect-, domain-oriented and generative programming + Macro-, reflective-, meta- and/or rule-based development approaches + Language design and implementation + Language integration, inter-operation and deployment + Development methodologies, support and environments + Educational approaches and perspectives + Experience reports and case studies Technical Program: ~~~~~~~~~~~~~~~~~~ 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 http://www.acm.org/about/class/1998 Submissions should be uploaded to Easy Chair, at the following address: http://www.easychair.org/conferences/?conf=els2011 Programme Chair ~~~~~~~~~~~~~~~~ Didier Verna - EPITA Research and Development Laboratory, France Local Chair ~~~~~~~~~~~~ Ralf Moeller - Hamburg University of Technology, Germany Programme Committee ~~~~~~~~~~~~~~~~~~~~ Antonio Leitao - Instituto Superior Tecnico/INESC-ID, Portugal Christophe Rhodes - Goldsmiths College, University of London, UK David Edgar Liebke - Relevance Inc., USA Didier Verna - EPITA Research and Development Laboratory, France Henry Lieberman - MIT Media Laboratory, USA Jay McCarthy - Brigham Young University, USA Jose Luis Ruiz Reina - Universidad de Sevilla, Spain Marco Antoniotti - Universita Milano Bicocca, Italy Manuel Serrano - INRIA, France Michael Sperber - DeinProgramm, Germany Pascal Costanza - Vrije Universiteit of Brussel, Belgium Scott McKay - ITA Software, USA -- Resistance is futile.

[cmucl-imp] Dec snapshots
by Raymond Toy 03 Dec '10

03 Dec '10

The December snapshot has been tagged. Binaries will be uploaded soon. A cross-compile is needed for this snapshot; use the boot-2010-11-1-cross.lisp files as the cross-compile script. You will get a restart so just choose the clobber-it restart. The compiler backend structure has changed to add a couple of new slots to hold the foreign linkage address and size. With this change (and a few more that will be coming soon), I can successfully do a cross-compile from x86 (OSX) to sparc.[1] This hasn't worked ever since linkage-tables was added because the linkage addresses of the compiling system were leaking into the target system. Ray [1] However, the resulting system cannot compile itself unless you comment out the callback stuff. I don't know why this happens. But if you do that, it compiles, and the result will also then compile itself with callback stuff enabled.
