CLASSIFICATION (2) Selectivity

• Criterion #2: Selectivity (S).

  • Explicit consistency maintenance related activities (e.g., invalidation) can be done on the entire cache memory (i.e., without any spatial discrimination), or on only a portion of the cache memory (i.e., selectively).

• Classes:

  • Indiscriminative schemes (i) as in [VEIDE86]
  • Selective schemes (s) as in [CHEO88a,CYTRO88,TARTA92]

• Comment:

  • The schemes referred to as selective are characterized with a wide range of granularity of data which can be the subject of the consistency maintenance activities.
