64-bit version of STK Engine available (beta)

We’ve just posted a new beta version for download on ADN: the 64-bit version of STK Engine v9.2.2. You can download it here.

This is a pretty solid release that passes the standard STK automated QA validations. However this version has not been widely used to develop and/or deploy real-world applications. Therefore we are making it available so you can try it out with your existing (or new) Engine applications. If you get a chance to try it, we would greatly appreciate your feedback!

The effort required to try this version should be minimal. Existing STK Engine licenses will work. Also, the 64-bit version can be installed side-by-side with the regular 32-bit package. The usual STK Engine development environments are supported (including .NET and Java). Switching between the 32-bit and 64-bit versions can be done with a few project changes in Visual Studio and Eclipse (assuming the rest of the code and libraries in your application compiles and runs for 64-bit). Notice that there are a few limitations with some of our third-party/business partner modules that are not yet supported.

For more information please check the PDF file available at the root of the zip file. It includes step-by-step instructions on how to get up and running with this beta version.

Enjoy our analytical, 2D and 3D capabilities in your 64-bit applications!

    That’s great news. Can you tell us about the implications, such as better handling of very large datasets, or any performance penalty for carrying around the additional bits? Has there been a performance evaluation between 32- and 64-bit STK Engine? Is there an example use-case of a task too large for the 32-bit version to handle, that the 64-bit version manages with ease, like a large coverage computation or similar?

  2. Sylvain says:

    The main advantage of the 64-bit version is the large amount of memory that can be addressed and used by your STK Engine applications. This makes it possible to process larger datasets (larger coverage grids for instance). Regarding performance we have not performed any formal comparisons between the 32-bit and 64-bit versions, so I do not have any hard number available. However, based on empirical data, the 64-bit version seems generally slightly faster than the 32-bit version.

    I want to install the 64-bit engine and just run it in the desktop environment (i.e not interested in application development). There don’t seem to be any instructions on how one would switch back and forth between the two versions (Visual Studio or Eclipse not involved) for checkout purposes. Do you have any written instructions on that?

  4. Sylvain says:

    At this point only STK Engine is available as 64-bit. The desktop environment is 32-bit only.
