Concrete changes are:

0.9b is out!

Thank you!

0.9b is almost ready!


0,9b release is almost ready!
In fact, it is already ready (and the corresponding code and 0.9b tag in the git repo),
but as I'm out of office now I cannot prepare and upload release files.
This will be done in the middle on July.

So, what's new in the 0.9b? Speedup and improvements (most in the sens. analyst), in details:
- sensitivity analyst steps are executed and rendered in parallel, in core this allows better multicore utilization, in ui this improves sens. analyst usability;
- in sensitivity analyst mode, when modelling is completed, in model view window there is improvement tooltips for entities: earlier there was shown chart only for last step, now for all the steps at the same time, enabling for quick overview what happend with model's entities during sensitivity analyst;
- in sensitivity analyst mode table data export exports not only the last step, but all the steps of the sensitivity analyst for the selected entities.... read more

Next Improvements to go


To keep you up to date just wanted to mention what are changes to be made in 0.9b and later.

As we posted earlier, we moved our execution engine to actor system.
What are the benefits:
- clearear multithreaded programming model
- improved ui responsiveness
- potentially better utilization of milticore systems
So there are also one cons: as of every modelling tick is done via sending messages between entities-actors and internally used HashedWheelTimer for thread scheduling, we have to spend at least 1ms for every modelling tick. In other words now we can't go faster than 1000 ticks per second.... read more

0.8b is out there!

And 0.8b finally there!
This is not feature but maintenance release in which major points are:
- Akka ( based model simulation -- for clearear programming model and basement for better multicore utilize on large models in future.
- Inno setup for windows installation -- for ease of use for Windows users
- updated dependencies - to be up-to-date!

Next releases will probably be pointed to improving performance and fixing bugs while we are on the way to define Sphinx SD Tools roadmap.... read more

GIT migration completed

Source code successfully migrated from svn to git.
Svn links is still accessible, but svn repo is outdated -- no new commmits will be performed on it, instead git repo will be used.

Also project layout have changed -- it become most likely maven layout with some additional folders. This let as clean up mess in the project root directory.

Eclipse project files is no longer in the repository (by the way development will be done in Intellij IDEA CE, but it doesn't matter) so you have to import project in your favourite IDE as MAVEN project and add some folders under src/main to the source folders. Detailed instructions will be supplied later in pdf docs.... read more

Migrating to GIT

We are resuming development process and first step is to move code repository from SVN to GIT.
SVN links will be removed as soon as first GIT commits will appear.
Some great features are one the way...
