 +From Lammps developer: "omputing forces in all single precision is a significant approximation and mostly works ok in homogeneous system, where there is a lot of error cancellation.
 +Using half precision in any form for force computations is not advisable."
  
 Keep track of this; does Amber run on the T4, the web site lists "Turing (SM_75) based cards require CUDA 9.2 or later." but does not list the T4 (too new?). Keep track of this; does Amber run on the T4, the web site lists "Turing (SM_75) based cards require CUDA 9.2 or later." but does not list the T4 (too new?).
