Detecting a stall condition associated with processor instructions within one or more threads and generating a no-dispatch condition. The stall condition can be detected by hardware and/or software before and/or during processor instruction execution. The no-dispatch condition can be associated with a number of processing cycles and an instruction from a particular thread. As a result of generating the no-dispatch condition, processor instructions from other threads may be dispatched into the execution slot of an available execution pipeline. After a period of time, the instruction associated with the stall can be fetched and executed.
