PRIORITY INVERSION

Domain	Definition
Computing	Priority inversion A phenomenon which can arise in a concurrent programming environment where a high priority task (H) is blocked by a low priority task (L), e.g. because L has locked some resource needed by H, and L then has to wait for a medium priority task (M). The net result is that H ends up waiting for M instead of the other way round - the priorities become inverted. This can be a problem if, for example, M takes a long time, causing H to miss a deadline. A possible cure is to have tasks inherit the maximum priority of any task that is waiting for them. In that case L temporarily becomes high priority until H can procede, thus preventing M from running in place of H. (1997-12-13). Source: The Free On-line Dictionary of Computing.
