If you have the line "__constant__ simulationConst cSim;" uncommented, that
probably means you are working outside the default GTI branch. The
nomenclature around this is pretty tricky, and involves a lot of aliasing
to switch between the new code paths (Amber18, which brings more C++
functionality into the layer between the original Fortran and the CUDA
kernels) and the old code paths (Amber16). Not sure what to tell you,
other than perhaps download the source anew and try re-installing.
