Current Released Version

6.0.014
(2016-11-10)
New in latest version

This new version has been completely rewritten under a more recent system providing support for addressing the multiple cores of the multicore processors. All the procedures have been parallelized in order to exploit multithreading, with as consequence a time execution decrease proportional to the number of cores.

6.0.000 - updated on 2014-07-24

This new version has been completely rewritten under a more recent system providing support for addressing the multiple cores of the multicore processors. All the procedures have been parallelized in order to exploit multi-threading, with as consequence a time execution decrease proportional to the number of cores.

Development is now written in Visual Basic with Microsoft Visual Studio 2010. The distributed software runs on Microsoft .Net Framework 4.0 under 32 and 64 bits platforms.
