当numa_set_strict(1)先执行,numa_alloc_onnode函数在预设结点没有内存空间的情况下,将不会回滚错误,直接返回分配内存失败。在分配内存之前,内核会尝试将node上的内存换出到硬盘,并清除其他缓存,这将会导致时延。 numa_allocinterleaved在系统上的所有结点分配交错(interleaverd)内存 void *mem = numa_alloc_interle...

VMA policy用来限制一个vm area的内存分配。此时需额外注意,它只作用于 anonymous pages(详见alloc_pages_vma)并且被使用同一个地址空间的task共享。VMA policy优先应用于task policy。 Linux memory policy 支持四种不同的模式——DEFAULT,BIND,PREFERRED,和INTERLEAVED。Default意味着用下级备选policy(系统的黙认policy...
