Table 3. Wall Times for an Acetone Molecule in a Water Cluster for the Two Different Update Schemes^a.

update scheme	successive	simultaneous
T(40), min	122.8	71.4
T(1), min	369.6	586.2
speedup	3.0	8.2
nFaT	6	10

^aT(X) represents the computational wall time obtained using X CPU cores. n_FaT gives the number of FaT iterations where it is necessary to reach convergence.
