(Pthread Library)

PTHREAD_SPUINHERIT_NP

Threads created with this processor attribute inherit their processor binding attributes from the

creating thread. This is the default value of the processor attribute. Specifying

PTHREAD_LDOMINHERIT_NP

or PTHREAD_SPUINHERIT_NP

cause both processor binding

and locality domain binding attributes to be inherited. The binding_type attribute is ignored.

PTHREAD_SPUFLOAT_NP

Threads created with this processor attribute are allowed to execute on any processor the system

chooses. No processor binding is maintained. Specifying

PTHREAD_LDOMFLOAT_NP

PTHREAD_SPUFLOAT_NP

cause both processor binding and locality domain binding attributes

to be cleared. The thread will be allowed to execute on any processor in the system. The

binding_type attribute is ignored.

(pthread_spu_t)

processor_id

Threads created with this processor attribute are bound to the processor speciﬁed in the proces-

sor parameter. The type of binding (advisory or mandatory) is speciﬁed in the binding_type

attribute.

PTHREAD_LDOMINHERIT_NP

Threads created with this processor attribute inherit their processor binding and locality domain

binding attributes from the creating thread. Specifying PTHREAD_LDOMINHERIT_NP

PTHREAD_SPUINHERIT_NP

cause both processor binding and locality domain binding attri-

butes to be inherited. The binding_type attribute is ignored. Due to differences in data types in

function deﬁnitions, this value should be cast to the type

(pthread_spu_t)

PTHREAD_LDOMFLOAT_NP

Threads created with this processor attribute are allowed to execute on any processor the system

chooses. No locality domain binding is maintained. Specifying PTHREAD_LDOMFLOAT_NP

PTHREAD_SPUFLOAT_NP

cause both processor binding and locality domain binding attributes

to be cleared. The thread will be allowed to execute on any processor in the system. The

binding_type attribute is ignored. Due to differences in data types in function deﬁnitions, this

value should be cast to the type

(pthread_spu_t)

(pthread_ldom_t)locality_domain_id

Threads created with this processor attribute are bound to the locality domain speciﬁed in the

processor parameter. The thread will be allowed to execute on any processor within the speciﬁed

locality domain. Due to differences in data types in function deﬁnitions, this value should be cast

to the type

(pthread_spu_t)

The legal values for the binding_type attribute (if the processor attribute is not

PTHREAD_SPUINHERIT_NP

, PTHREAD_SPUFLOAT_NP, PTHREAD_LDOMINHERIT_NP

,or

PTHREAD_LDOMFLOAT_NP

) are:

PTHREAD_BIND_ADVISORY_NP

Threads created with this binding_type attribute have advisory processor binding to the proces-

sor speciﬁed in the processor attribute. Refer to pthread_processor_bind_np(3T) for more infor-

mation on advisory binding.

PTHREAD_BIND_FORCED_NP

Threads created with this binding_type attribute have forced (or mandatory) processor binding to

the processor speciﬁed in the processor attribute. Refer to pthread_processor_bind_np(3T) for

more information on forced binding.

PTHREAD_BIND_LDOM_NP

Threads created with this binding_type are bound to the locality domain speciﬁed in the proces-

sor attribute. Refer to pthread_ldom_bind_np(3T) for more information on locality domain bind-

ing.

PTHREAD_BIND_NONE_NP

Threads created with this binding_type are not bound to any processor or locality domain. The

processor attribute is ignored. This is the default value of the binding_type attribute.

The default value of the processor attribute is PTHREAD_SPUINHERIT_NP. The default value of the

binding_type attribute is

PTHREAD_BIND_NONE_NP.

pthread_attr_setprocessor_np() is used to set the processor and binding_type attributes in the

initialized attributes object attr. The new values of the processor and binding_type attributes are passed to

this function in the processor and binding_type parameters, respectively.
