Welcome to Dinamica EGO 5

Congratulations! You have successfully installed Dinamica EGO 5!

(See the changelog specific for version 5.2.0)

Model execution might fail, if you are upgrading from a previous version of Dinamica EGO with the Enhancement Plugin [allowing the use of R as part of a Dinamica EGO model] and there are R packages that were downloaded and installed previously by Dinamica itself.If that happens, open the Options dialog (Tools -> Options), then choose Integration, and click on “Purge User Installed Packages...” to remove all installed packages. The removed packages will be reinstalled again next time the model is executed.

What is New

Dinamica EGO 5 brings several groundbreaking improvements in several areas:

Execution

The parallel execution system was rebuilt from scratch making this the fastest Dinamica EGO ever! Now, the parallel execution uses a fixed number of execution threads (called workers) with task stealing to provide load balancing and increase the flexibility of how parallel tasks can be designed. In theory, all model components can run in parallel:

Independent functors run in parallel;

Independent loop steps run in parallel;

Different pieces of a map are loaded in parallel.

Individual settings in the Execution tab of the Options dialog controls how parallel execution works.

Thousands of internal optimizations.

Now images are manipulated in parallel even when they are too big to fit in memory.

Additional new options to control how memory allocation for maps works.

[EXPERIMENTAL] Certain functors can have their execution accelerated using GPUs (called accelerators). The use of Nvidia and AMD GPU card models released after 2016 is advised.

Internationalization

Now it is possible to provided file paths, and also comments and alias for functors in almost any language. The graphical interface itself is still available only in English, though.

Integration

Improved integration with R: It is now possible to install packages even if R is being provided by the Enhancement Plugin. Just replace the typical import statement 'library (NAME)' with 'dinamicaPackage(“NAME”)' when importing packages from your scripts. By doing so, packages will be automatically downloaded and installed, if necessary. An option in the Tools->Options dialog defines the mirror repository from where R packages are downloaded by Dinamica EGO.

Integration with Python: Python can now be used to create functors, via calculate_python_expression_pt as part of the models. It is now possible to install packages by using 'dinamica.package(“NAME”)' when importing packages. Similarly how it works for R, Python packages will be automatically downloaded and installed from the PIP repository, if necessary. Packages can also be installed from custom locations. And unlike R, the Python interpreter is deployed with Dinamica EGO, so it is possible to use Python to create functors out of the box.

Portable

Windows version of Dinamica EGO can now be used without having to be installed (portable version). However, the full installer is still recommended for easier deployment and for a better overall experience.

Submodels

Submodels and functors can now be nested with multiple levels in the Functor Library tree.

Submodels can show their inputs in custom tabs (other than the default or advanced tabs) in the Functor Editor dialog.

Submodels are loaded “lazily” when the application starts. As the result, Dinamica tends to initialize very quickly, even when dozen of submodels are installed.

Miscelaneas

More uniform settings (variables and registry). Most settings can be overridden using an environment variable for convenience.

Virtualization Off is no longer available.

New command line tool.

Thousands of bug fixes.

Platform

Dinamica EGO 5 is 64-bit only application.

Compiled using the latest compilers.

Available for Windows, Linux and Mac.

Videos

We are still updating the documentation, including the guidebook, to cover features available on the new version of Dinamica EGO. Meanwhile, check some short videos showing how to use some of the features of the new release.

Additional Plugins

It is also possible to download and install the Enhancement Plugin for Dinamica EGO. This plugin can be used to speed up the execution of some Dinamica EGO operators under certain circumstances and it also allows R scripts to be used as part of Dinamica EGO models.
