- processor farm — (computer, parallel) A parallel processor where tasks are distributed, or "farmed out", by one "farmer" processor to several "worker" processors, and results are sent back to the farmer. This arrangement is suitable for applications which can be partitioned into many separate, independent tasks, the canonical examples being ray tracing and the Mandelbrot set. In order to be efficient, the extra time spent on communications must be small compared to the time spent processing each task.
- processor time — (software) The amount of time a process takes to run, given that it has exclusive and uninterrupted use of the CPU. Note that in a modern computer, this would be very unusual, and so the processor time calculation for most processes involves adding up all the small amounts of time the CPU actually spends on the process. Some systems break processor time down into user time and system time. Compare wall clock time.
