par-affinity, Qpar-affinity
Specifies thread affinity. This feature is only available for ifort.
Syntax
Linux:  |  
      -par-affinity=[modifier,...]type[,permute][,offset]  |  
     
Windows:  |  
      /Qpar-affinity:[modifier,...]type[,permute][,offset]  |  
     
Arguments
modifier  |  
      Is one of the following values: granularity={fine|thread|core|tile}, [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.  |  
     
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.  |  
     
Default
OFF  |  
      The thread affinity is determined by the runtime environment.  |  
     
Description
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:
You have specified option [Q]parallel or option [q or Q]openmp (or both).
You are compiling the main program.
This option may behave differently on Intel® microprocessors than on non-Intel microprocessors.
