常用示例
Set NUMA policy for memory range (C code)
mbind([addr], [length], MPOL_BIND, [&nodemask], [maxnode], 0)
Bind memory to specific node
mbind([ptr], [size], MPOL_BIND, [&mask], [maxnode], MPOL_MF_MOVE)
Interleave memory across nodes
mbind([addr], [len], MPOL_INTERLEAVE, [&nodemask], [maxnode], 0)
说明
mbind is a system call that sets the NUMA memory policy for a specified memory range. It controls which NUMA nodes are used for memory allocation within that range. This is used for performance optimization on NUMA systems by controlling memory locality.
