The development of 64-bit applications has become more important in the last couple of years and it even seems to have become the standard. The migration to a 64-bit version of MATLAB for the DRDC Valcartier Weapons Systems section was not really an option since Mathworks announced that the R2015b version of MATLAB will be the last release of the 32-bit version of the software for Windows. This means that the Weapons Systems Library (WSL), which is MATLAB/Simulink based, would no longer be supported for future versions. In addition, various softwares which are MATLAB based will also need to be updated to 64-bit, which is mainly due to software components interoperability with the 64-bit versions of MATLAB that requires that the other software also be 64-bit. As part of the W7701-155932 R&D Weapon System project, the mandate regarding the system migration was mainly to make sure that such a migration would not impact on model stability, compiling behavior, and scenarios results within the DRDC MATLAB/Simulink library as well as in the BAE SADM simulation software. The current report will study the effects of the aforementioned software migration on scenarios simulation results from both SADM and WSL and their use of DRDC library models, by investigating the parameters initialization, run time and compilation time. Computing performances assessment will be performed using statistical tests in order to compare 32 and 64-bit tests and to check for substantial variation on samples
