Linux: | -par-affinity=[modifier,...]type[,permute][,offset] |
Mac OS X: | None |
Windows: | /Qpar-affinity:[modifier,...]type[,permute][,offset] |
modifier |
Is one of the following values: granularity={fine|thread|core}, [no]respect, [no]verbose, [no]warnings, proclist=proc_list. The default is granularity=core, respect, and noverbose. For information on value proclist, see Thread Affinity Interface in Optimizing Applications. |
type |
Indicates the thread affinity. This argument is required and must be one of the following values: compact, disabled, explicit, none, scatter, logical, physical. The default is none. Values logical and physical are deprecated. Use compact and scatter, respectively, with no permute value. |
permute |
Is a positive integer. You cannot use this argument with type setting explicit, none, or disabled. The default is 0. |
offset |
Is a positive integer. You cannot use this argument with type setting explicit, none, or disabled. The default is 0. |
OFF |
The thread affinity is determined by the run-time environment. |
This option specifies thread affinity, which binds threads to physical processing units. It has the same effect as environment variable KMP_AFFINITY.
This option overrides the environment variable when both are specified.
This option only has an effect if the following is true:
Linux* OS: You have specified option -parallel or -openmp (or both).
Windows* OS: You have specified option /Qparallel or /Qopenmp (or both).
You are compiling the main program.
