thrash
     
        To move wildly or violently, without accomplishing anything
        useful.  {Paging} or {swapping} systems that are overloaded
        waste most of their time moving data into and out of {core}
        (rather than performing useful computation) and are therefore
        said to thrash.  Thrashing can also occur in a {cache} due to
        {cache conflict} or in a {multiprocessor} (see {ping-pong}).
     
        Someone who keeps changing his mind (especially about what to
        work on next) is said to be thrashing.  A person frantically
        trying to execute too many tasks at once (and not spending
        enough time on any single task) may also be described as
        thrashing.
     
        Compare {multitask}.
