**yaml value** seq | usize
|
|
|
|
A `CPU_SET(3)`_ for use with `sched_setaffinity(2)`_.
|
|
|
|
The value should be a CPU ID, starting from 0, or a sequence of CPU IDs.

unaided runtime config
|
|
======================
|
|
|
|
**yaml value**: map
|
|
|
|
This is the config for unaided runtime.
|
|
|
|
The keys are:
|
|
|
|
thread_number
|
|
-------------
|
|
|
|
**optional**, **type**: usize
|
|
|
|
Set the thread number.
|
|
|
|
**default**: the number of logic CPU cores
|
|
|
|
thread_stack_size
|
|
-----------------
|
|
|
|
**optional**, **type**: :ref:`humanize usize <conf_value_humanize_usize>`
|
|
|
|
Set the stack size for worker threads. For *<int>* value, the unit is bytes.
|
|
|
|
**default**: system default
|
|
|
|
sched_affinity
|
|
--------------
|
|
|
|
**optional**, **type**: map | bool
|
|
|
|
Set the sched affinity for each threads.
|
|
|
|
For map value, the key should be the thread id starting from 0, and the value should be :ref:`cpu set <conf_value_cpu_set>`.
|
|
|
|
For bool value:
|
|
|
|
* if true, a default CPU SET will be set for each thread, the CPU ID in the set will match the thread ID.
|
|
|
|
* if false, no sched affinity will be set, just as if this config option is not present.
|
|
|
|
**default**: no sched affinity set
|
