Currently Vectors only tests the “default” SIMD architecture which is usually the “best” one a given processors supports. This however leaves less often used architectures untested eg. single precision ones or ones supported by old processors.

The pull request https://bitbucket.org/cactuscode/cactusutils/pull-requests/26/rhaas-testall/diff uses some include file trickery to test all possible architectures.
