CONFIG_RCU_FANOUT: Tree-based hierarchical RCU fanout value

General informations

The Linux kernel configuration item CONFIG_RCU_FANOUT:

Help text

This option controls the fanout of hierarchical implementations of RCU, allowing RCU to work efficiently on machines with large numbers of CPUs. This value must be at least the fourth root of NR_CPUS, which allows NR_CPUS to be insanely large. The default value of RCU_FANOUT should be used for production systems, but if you are stress-testing the RCU implementation itself, small RCU_FANOUT values allow you to test large-system code paths on small(er) systems.

Select a specific number if testing RCU itself. Take the default if unsure.
