IPUCOM Program
Considerations
•
The IPUCOM program can be run without super-group or other privileges, but to
alter any of the process or CPU-wide settings, the user must conform to the
security requirements of a corresponding call to IPUAFFINITY_SET_ or
IPUAFFINITY_CONTROL_.
See the Guardian Procedure Calls Reference Manual for details on the
requirements of those interfaces.
Note that in particular the user of IPUCOM must be locally logged in to alter any of
the process or the CPU-wide settings.
•
A customer may choose to give the IPUCOM program to a SUPER group member
and then set PROGID on it. They can then use either Safeguard ACLs or standard
file security to control execution access. It is not shipped with PROGID set.
For more information about the restrictions and requirements on the use of IPUCOM,
see the considerations for the IPUAFFINITY_GET_, _SET_, and _CONTROL_
procedures in the Guardian Procedure Calls Reference Manual.
Examples
The following example sets the primary $XYZ process on IPU 1:
IPUCOM -pname $xyz 1
The following unbinds the primary $XYZ process, allowing it to be moved again by the
process scheduler:
IPUCOM -pname $xyz unbind
The following displays the IPU affinity of the $XYZ process:
IPUCOM -pname $xyz info
The following sets the process that is PIN 456 in CPU 3 on IPU 2:
IPUCOM -pin 456 -cpu 3 2
The following turns off DP2 balancing in the process scheduler in CPU 5:
IPUCOM -cpu 5 -balanceDP2 off
