CPU backend

All CPU related settings contains in one cpu object in config file, CPU backend allow specify multiple profiles and allow switch between them without restrictions. Default auto-configuration create reasonable minimum of profiles which cover all supported algorithms.

Example

Example below demonstrate all primary ideas of flexible profiles configuration:

• "rx/wow" Exact match to algorithm rx/wow, defined 4 threads without CPU affinity.
• "cn" Default failback profile for all cn/* algorithms, defined 2 threads with CPU affinity, another failback profiles is cn-lite, cn-heavy and rx.
• "cn-lite" Default failback profile for all cn-lite/* algorithms, defined 2 double threads with CPU affinity.
• "custom-profile" Custom user defined profile.
• "*" Failback profile for all unhandled by other profiles algorithms.
• "cn/r" Exact match, alias to profile custom-profile.
• "cn/0" Exact match, disabled algorithm.

Intensity

This option was known as low_power_mode, possible values is range from 1 to 5, for convinient if value 1 used, possible omit this option and specify CPU thread config by only one number: CPU affinity, instead of object.
