[PATCH OLK-5.10 V1] sched: Support NUMA parallel scheduling for multiple processes
by Cheng Yu 04 Jun '25
by Cheng Yu 04 Jun '25
04 Jun '25
hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/ICBBNL
--------------------------------
For architectures with multiple NUMA node levels and large distances
between nodes, a better approach is to support processes running in
parallel on each NUMA node.
The usage is restricted to the following scenarios:
1. No CPU binding for user-space processes;
2. It is applicable to distributed applications, such as business
architectures with one master and multiple slaves running in
parallel;
3. The existing "qos dynamic affinity" and "qos smart grid" features
must not be used simultaneously.
