It is a pleasure to use this Monday released GAMESS2018R3 binary for macOS to try the method for CH, and have repeatedly got the identical energies of CCSDt, cc(t,3), ect., with official GAMESS results, and one note:
...
Note: The following floating-point exceptions are signalling: IEEE_DENORMAL
ddikick.x: exited gracefully.
Actually the precompiled binary has made the calculation successful.
The cpu needs to be updated.
The energies calculated by the benchmarkable CCSDT of NWCHEM6.8 for CH, repeated on Ubuntu and MAC OS 10.13.6 and almost identical, using the same geometry, same symmetry, and same kind of basis set are only from 0.00333 to 0.00175 hartrees different from all those obtained from GAMESS according to the original active-space setting.
