The {configuration} category prints some information about the

The {memory} category prints some information about the current

allocated memory reported by LAMMPS classes). Where supported,

request memory from) and the maximum resident set size is reported

The {time} category prints the accumulated CPU and wall time for the

The {configuration} command prints some information about the LAMMPS

information about the memory consumption provided by the OS is
reported.
