5.20 CPUPRIO (CPU
thread process priority)
5.20.1 Function
CPUPRIO specifies the priority of the CPU thread. See section
details. Default is a nice value of 15, which means a low priority such that I/O can be scheduled and com-
pleted in favour of CPU cycles. On multi-CPU systems a real CPU can be “dedicated” to Hercules by
giving the CPU-thread a very high dispatching priority (-20).
Caution: CPUPRIO should not have a higher dispatching priority than the TOD clock and timer thread.
