numa_balancing This parameter enables or disables automatic NUMA memory balancing. On NUMA machines, there is a performance penalty if remote memory is accessed by a CPU. For more details, see Kernel sysctl documentation. numa_balancing_scan_period_min_ms, numa_balancing_scan_delay_ms,...

所以,在BIOS是默认值时,上图就是成立的,我只要申请的内存块足够大,超过了一个NUMA节点Free内存的上限,OS一定会从另一个NUMA节点上分配内存。也就是,我所申请的内存块,虚拟地址一部分映射到NUMA 0,另一个部分映射到NUMA 1。 如果进程在CPU 0上运行,它会尝试从NUMA 0上分配所有内存。NUMA 0上内存不够了,再...
