8.39.3 Parameter

model

Any valid 4 digit hexadecimal CPU model number. A list of the valid model numbers
can be found in the Hercules Windows GUI file “cpu-types.txt”.

8.39.4 Examples

Example 1:

Specify a 7060 CPU model.

HHC00013I Herc command: 'cpumodel'

HHC02203I cpumodel : 7060

8.40 CPUPRIO (Display or set CPU thread process priority)

8.40.1 Function

The CPUPRIO command is used to change the priority of the CPU thread. See section

5.82 for details on
process and thread priorities. On multi-CPU systems a real CPU can be “dedicated” to Hercules by giving
the CPU-thread a very high dispatching priority (-20). Given without an argument the CPUPRIO com-
mand displays the current CPU thread process priority.

Caution: CPUPRIO should not have a higher dispatching priority than the TOD clock and timer thread.

8.40.3 Parameter

nn

This value specifies the priority for the CPU thread. For details on the priority
values see section

5.82 (“Process and Thread Priorities”).

8.40.4 Examples

Example 1:

Set the CPU process priority to -20.

HHC00013I Herc command: 'cpuprio -20'

HHC02204I cpuprio set to -20
