Definition of atomicity in US English:



  • 1Chemistry
    The number of atoms in the molecules of an element.

    • ‘In other words, as this encyclopedia entry says, a molecule of oxygen has an atomicity of 2.’
    • ‘Taking into account the conservation of atoms we may determine all transition atomicities and represent atomic channels as graphs of distribution of atoms.’
  • 2The state or fact of being composed of indivisible units.

    • ‘A very simple consistency requirement is that of failure atomicity: the application either terminates normally, producing the intended results, or is aborted, producing no results at all.’
    • ‘CDP-based restoration provides atomicity, offering a holistic data set which can be recovered whether or not an application was quiescent at the moment of recovery.’
    • ‘In this paper, we deal with the problem of atomicity and isolation in the context of processes.’
    • ‘There have been a number of cases presented where atomicity over a group of operations has been desirable.’
