This document describes how affinity of whole process or single thread can be assigned

Using taskset to start dabc

Already before it was possible to specify taskset arguments for complete dabc process in <Run> section in the form like <taskset value="-c 10-15"/>. This is used in dabc_run script.

Assign special arguments for the main process

One can specify default affinity for every new created thread, providing "affinity" parameter in <Run> section. Value can be following:

• unsigned value with processors mask
• string like "xxxoooxxxss" with allowed symbols 'x', 'o' and 's'. 'x' - enabled, 'o' - disabled, 's' - special purpose first element in string corresponds to first processor
• string like "-N" where N is processors number which should be reserved for special purposes. These processors could be later assigned with SetAffinity("+M") call (M<N)

Individual settings for the thread

For every thread attribute "affinity" could be specified. Allowed values:

• unsigned value with processors mask
• string like "xxxoooxxx" were x and o identified enabled and disabled processors, first element in string corresponds to first processor
• string like "+M" where M is processor number in special processors set, before SetDfltAffinity("-N") should be called (M<N)
