1.$ SHOW CPU
SOWHAT, A VAX 8800
Multiprocessing is ENABLED. Full checking synchronization image
loaded.
Minimum multiprocessing revision levels: CPU = 0 uCODE = 0 UWCS = 0.
PRIMARY CPU = 01
Active CPUs: 00 01
Configured CPUs: 00 01
The SHOW CPU command in this example produces a configuration
summary of all configured processors in the VAX 8800 system
SOWHAT. The primary processor is CPU 01, and all configured
processors are active.
2.$ SHOW CPU/BRIEF
SOWHAT, A VAX 8800
Multiprocessing is ENABLED. Full checking synchronization image
loaded.
Minimum multiprocessing revision levels: CPU = 0 uCODE = 0 UWCS = 0.
PRIMARY CPU = 01
CPU 00 is in RUN state
Current Process: AIREGIN PID = 4A8001E5
CPU 01 is in RUN state
Current Process: ***None***
The SHOW CPU/BRIEF command in this example produces a
configuration summary of the VAX 8800 system SOWHAT and also
indicates that its two processors are in the RUN state. Only
CPU 00 has a current process.
3.$ SHOW CPU/FULL
BIG1, a AlphaServer 4100 5/466 4MB
Multiprocessing is ENABLED. Full checking synchronization image loaded.

The SHOW CPU/FULL command in this example produces a
configuration summary of the AlphaServer 4100 5/466 4MB system,
BIG1. All are in the RUN state and all have a current process.
Note that NETACP can only run on CPU 0, because only CPU 0 has
primary capability. Note also that CPUs 1 and 2 have Fastpath
ports, PKC0 and PKB0 respectively assigned.
4.$ SHOW CPU/FULL
OLEO, A VAX 6000-420
Multiprocessing is DISABLED. MULTIPROCESSING System parameter = 02
Minimum multiprocessing revision levels -- CPU: 0 uCODE: 0 UWCS: 21.
PRIMARY CPU = 02
*Loaded unmodified device drivers prevent multiprocessor operation.*
RBDRIVER
CPU 02 is in RUN state
Current Process: Koko PID = 2A6001E3
Revision levels: CPU: 0 uCODE: 0 UWCS: 0.
Capabilities of this CPU:
PRIMARY VECTOR RUN
Processes which can only execute on this CPU:
CONFIGURE PID = 2A40010B Reason = PRIMARY Capability
Reason = RUN Capability
CPU 07 is in INIT state
Current Process: *** None ***
Revision levels: CPU: 0 uCODE: 0 UWCS: 0.
Capabilities of this CPU:
*** None ***
Processes which can only execute on this CPU:
*** None ***
The SHOW CPU/FULL command in this example produces a
configuration summary of the VAX 6000-420 system OLEO,
indicating that only CPU 02, the primary CPU, is active and
in the RUN state. It also shows that there is a uniprocessing
driver loaded in the system, thus preventing the system from
being enabled as a multiprocessor.
5.$ SET PROCESS /AFFINITY /SET=3 SYSTEM/PERMANENT

Bindings:
SYSTEM PID = 00000438 Reason: Affinitized to this CPU
Features:
AUTOSTART is enabled.
Disabled for use as a Fastpath Preferred CPU.
Fastpath ports assigned to this CPU:
PNA0 (user assigned)
In this example, the SYSTEM process has its affinity set
permanently to CPU3. The SHOW CPU command indicates this is
the BINDINGS list.
The port PNA0 was assigned to CPU 3 by a user when CPU 3 was
enabled as a Fast Path preferred CPU. Subsequent to that
operation, CPU 3's bit was cleared in the IO_PREFER_CPUS
system parameter. This disabled CPU 3 for use as a Fast Path
preferred CPU. Normally this is a transient condition, as
changing IO_PREFER_CPUS results in the FASTPATH_SERVER process
redistributing the Fast Path ports across the set of usable
CPUs.
However, if there is no FASTPATH_SERVER process, PNA0 remains
assigned to this CPU until any of the following actions occur:
1. The user tries to move the port to another CPU by using the
SET DEVICE/PREFERRED_CPU command, $QIO, or the $IO_FASTPATH
system service.
2. The CPU is stopped.
