#11: Allow for the possibility of using the bytecode representation of the model for any task ---------------------------+------------------------------------------------ Reporter: sebastien | Owner: ferhat Type: enhancement | Status: closed Priority: major | Milestone: 4.2 Component: Preprocessor | Version: Resolution: fixed | Keywords: ---------------------------+------------------------------------------------ Changes (by ferhat): * status: accepted => closed * resolution: => fixed Comment: - Extends the algorithms compatible with bytecode to compute the steady- state. The new values for solve_algo are: * 0: fsolve * 1: solve1 * 2, 4: solve1 + block decomposition * 3: csolve * 5: LU decomposition with UMFPack (method handling sparse matrix in Matlab) * 6: GMRES * 7: BiCGStab * 8: bytecode own solver (use gaussian elimination + sparse matrix) -- Ticket URL: <https://www.dynare.org/trac/ticket/11#comment:4> Dynare <http://www.dynare.org> The Dynare project

Dynare 4.2 release goals and schedule
by Sébastien Villemot 11 Oct '10

11 Oct '10

Hi, I summarize in this e-mail the main release goals for Dynare 4.2, with the name of the responsible person(s) and the associated ticket numbers. Note that there are many other tickets – in particular bugs which need to be fixed – but I only list here the outstanding intended new features : - Symbolic computation of the first order conditions of the Ramsey problem (Sébastien) [#5] - Use of a seed to make estimation deterministic (Michel, Stéphane) [#85] - Estimation with unexpected structural changes (Stéphane) [#13] - Partial information (George) [#21] - Markov-Switching BVAR (Houtan, Michel) [#24] - Automatic generation of the stationary model, given the trends (Houtan) [#19] - Local identification (Marco) [#31] - Parallelization system (Marco, Sébastien) [#55] - Constrained parameters for OSR (Michel) [#58] - Possibility of using the bytecode representations for most tasks (Ferhat, Sébastien) [#11] - User guide: refresh outdated parts, add new chapter on optimal policy (Tommaso, Michel) [#17] The goal is to release the 4.2 version by the beginning of november, which means that the various features should be ready by mid-october. Note that by “ready” I mean that the features must be working reasonably well, have an interface in the MOD-file, be documented (at least on the wiki, preferably in the reference manual), and come with test files in the appropriate directory. Of course I can help you concerning these various aspects, in particular for the interface (which require preprocessor changes) and for the build system. Let me know if you think that you cannot achieve completion of the features that you are responsible for by the mid-october deadline. We will then decide whether to postpone the feature for 4.3 or to delay the release of 4.2.
