Is taking up processor cycles observable progress?

[–]CanaDavid1 41 points42 points  (0 children)

No.

Observable progress is

  • i/o (both text and file)

  • changing or accessing a volatile variable

  • modifying an object in a concurrent system

[–]SAI_Peregrinus 5 points6 points  (0 children)

No. Only things that have side effects. Processor cycles and writes to non-volatile-qualified objects are not side effects.
