Attributes for Better Manageability
HP-UX Processor Sets define a set of attributes that allow users to control system behavior
for various operations on processor sets. A processor set has default attribute values when
started. Users may explicitly change the value of an attribute as needed. HP-UX processor
sets support the following attributes and attribute values:
PSET_ATTR_OWNID
The UID (user id) of the processor set owner. At processor set creation time, the
effective user ID of the creator is assigned as the owner.
PSET_ATTR_GRPID
The GID (group id) of the processor set owner. The creator's effective group ID is
assigned at processor set creation time.
PSET_ATTR_PERM
The access permission bit mask for the processor set. These permissions, listed
below, are defined similar to file access permissions:
READ
User can query the processor set attributes.
EXEC
User can bind its process or thread to the processor set.
