[Pharo-project] RoarVM: The Manycore SqueakVM
by Stefan Marr Nov. 3, 2010

Nov. 3, 2010

Dear Smalltalk community: We are happy to announce, now officially, RoarVM: the first single-image manycore virtual machine for Smalltalk. The RoarVM supports the parallel execution of Smalltalk programs on x86 compatible multicore systems and Tilera TILE64-based manycore systems. It is tested with standard Squeak 4.1 closure-enabled images, and with a stripped down version of a MVC-based Squeak 3.7 image. Support for Pharo 1.2 is currently limited to 1 core, but we are working on it. A small teaser: 1 core 66286897 bytecodes/sec; 2910474 sends/sec 8 cores 470588235 bytecodes/sec; 19825677 sends/sec RoarVM is based on the work of David Ungar and Sam S. Adams at IBM Research. The port to x86 multicore systems was done by me. They open-sourced their VM, formerly know as Renaissance VM (RVM), under the Eclipse Public License [1]. Official announcement of the IBM source code release: http://soft.vub.ac.be/~smarr/rvm-open-source-release/ The source code of the RoarVM has been released as open source to enable the Smalltalk community to evaluate the ideas and possibly integrate them into existing systems. So, the RoarVM is meant to experiment with Smalltalk systems on multi- and manycore machines. The open source project, and downloads can also be found on GitHub: http://github.com/smarr/RoarVM http://github.com/smarr/RoarVM/downloads For more detailed information, please refer to the README file[3]. Instructions to compile the RoarVM on Linux and OS X can be found at [4]. Windows is currently not supported, however, there are good chances that it will work with cygwin or pthreads for win32, but that has not be verified in anyway. If you feel brave, please give it a shot and report back. If the community does not object, we would like to occupy the vm-dev(a)lists.squeakfoundation.org mailinglist for related discussions. So, if you run into any trouble while experimenting with the RoarVM, do not hesitate to report any problems and ask any questions. You can also follow us on Twitter @roarvm [5].

Re: [Pharo-project] XML package is barking at load time

Probably the configuration in the Project is not up to date. The pattern should be publish and maintain a configuration per project (imagine that metacelloRepository vanish tomorrow) copy the config from time to time to Metacello Alex is it you that maintain the configurationOfXMLSupport? The new publish mechanism dale is working on will probably save this problem.

[Pharo-project] Shrinking image much more slow in Windows than MACOSX
by nullPointer Nov. 3, 2010

Nov. 3, 2010

IÂ´m developing a wizard for prepare a deploy in Pharo. IÂ´m using predefined routines of system like Scriptloader>>cleanUpForproduction SmalltalkImage>>cleanUp: false SmalltalkImage>>disableProgrammerFacilities or manual delete from system packages too. I can delete many MB from image with that mechanism, but the problem is when that routines is much much more slow on Windows than MACOSX. Is possible do something in Windows for enhance? the difference is huge...

I mean not having refactoring phases after expansion phase during 10 years is not good. You get a system that shows its ages while it could be really sexy.

[Pharo-project] Postdoctorate positions available
by Serge Stinckwich Nov. 3, 2010

Nov. 3, 2010

Hi guys, i've got some ANR (french research agency) funding for a postdoctorate position (18 months) to work on domain-specific languages and tools for mobile robotics systems in the context of the PROTEUS (Platform for RObotic models Transformations and Exchange between Users and Scientific communities) project. Applicants should have a PhD in one of the following disciplines: software engineering or robotics. Very good programming skills are required. My research team also got recently some funding (less funded than the previous one) for 2 postdoctorate positions (10 months) but could not find anyone at the moment ... The original description of these positions are available here: http://www.ifi.auf.org/site/content/view/239/85/ but now we are no more focusing on these subjects. I'm looking for people that are interested to work on domain-specific languages for robotics and/or applications of robotics/wireless sensors networks for environmental surveillance and disaster management. The location for all these positions is Ha Noi, Vietnam in the UMMISCO research team. UMMISCO is an international joint research unit between severals research team including IRD (Institut de Recherche pour le DÃ©veloppement) and the University of Paris 6. Interested candidates should submit ASAP a Curriculum Vitae, a summary of the research background and interests by e-mail to me (Serge.Stinckwich(a)gmail.com) English writing fluency is a must. English speaking fluency is necessary, especially if the applicant does not speak French. Regards, -- Serge Stinckwich UMI UMMISCO 209 (IRD/UPMC), Hanoi, Vietnam Every DSL ends up being Smalltalk http://doesnotunderstand.org/

But I used a web code browser for Seaslides (see http://picasaweb.google.com/lh/photo/uZxVgeeGwSOMW86-QeHbSQ?feat=directlink ) which is basically a WABrowser subclass + Bespin (now Skywriter) so it has at least one usage :). > > I've just discovered http://www.ymacs.org/ (demo http://www.ymacs.org/demo/ ) and it seems a web browser can be a good candidate as a portable IDE. > > It may be easier today to experiment with GUI in a Web Browser than in Morphic. Yes But Smalltalker looks for it when you see the state of morphic Stef

can you publish that in a bug entry so that we do not forget?
