Trac for Dynare
by Sébastien Villemot 27 Aug '09

27 Aug '09

Hi, I have just installed a Trac for Dynare, available at the adresse: http://www.dynare.org/trac Trac is a project management software. It helps developers to deal with bugs, features to be added, deadlines, ... The basic item is a "ticket". A ticket is typically a bug report, or a feature to be added. The ticket is closed once the bug is fixed, or the feature is implemented. Users can spawn a discussion on a ticket. A ticket can be assigned: * a priority level * a type (bug, feature...) * a component (the part of Dynare to which it relates: the preprocessor, the core M-files, such DLL, the doc...) * a milestone (to be done for Dynare 4.1, for Dynare 4.2) * an owner (the person who is responsible for fixing the bug or adding the feature) * a version (4.0.1, 4.0.2, ...) (only useful for bug reports) I have already added some tickets, corresponding to the main release goals for Dynare 4.1, which is planned for the end of september. See "View tickets". The "Roadmap" lists the future milestones, currently 4.1 and 4.2. For each milestone, there is a deadline, and also the percentage of the tickets assigned to that milestone that have been closed. You can also browse the subversion repository through "Browse source". The "Timeline" lists all the recent changes (including SVN commits). You can syndicate to this timeline in your favorite RSS aggregator. Finally there is a wiki, which is a little bit redundant with the already existing DynareWiki. We may decide not to use it, or we may use it only for development specific stuff, and dedicate the other wiki to public documentation and other Dynare-related stuff. In order to add/modify tickets or wiki pages you need to be logged in. The usernames and password are exactly the same than for the SVN repository of Dynare. Please don't hesitate to add new tickets for the bugs you discover, or for the features you plan to add. Also please take ownership of existing tickets if you plan to deal with them. At a later date we may allow user to open tickets for bug reports, if we think we can avoid useless or wrong bug reports. Best, -- Sébastien Villemot

MATLAB bug on Linux/64
by Sébastien Villemot 19 Aug '09

19 Aug '09

Hi everyone, I am hitting a MATLAB bug which is driving me crazy. I attach two files: plouf.m and plouf_static.m. They are derived from preprocessor-generated files with the EAGLE model. The script "plouf.m" calls the function "plouf_static.m". When I run "plouf.m" on a Linux/64 machine, MATLAB crashes with a bus error (tested on Karaba and Hal, with Matlab 7.5, 7.6 and 7.8). This does not happen on Linux/32 or Windows/32. I have not tested other platforms. As can be seen from the displayed marks which I have inserted, MATLAB crashes around line 131 of plouf_static.m. More precisely, it seems to crash just after having computed the expression there. I can't understand exactly what's going on. Can you reproduce this? Note that I have observed similar crashes with other big models on Karaba. Since so far I cannot precisely pinpoint what triggers the bug, I don't know how to make a workaround. So for the moment, for the development of EAGLE, I am going to use Matlab/32 in a virtual machine on Karaba. Probably we should send a report to Mathworks. Best, -- Sébastien Villemot

model derivatives with respect to parameters
by Michel Juillard 19 Aug '09

19 Aug '09

Dear Nikolay, we have started to work on producing the derivatives with respect to parameters. We are planing to create a new function, that will return a 3-dimensional array, by equation, variable and parameter. You could then select one parameter and squeeze the array in the parameter dimension to obtain a matrix of Jacobian derivatives with respect to a given parameter. Do you see any problem with this implementation? We should be able to provide in about two weeks. All the best, Michel
