H A Dtmpfs.rst76 mpol=default 採用進程分配策略
78 mpol=prefer:Node 傾向從給定的節點分配
79 mpol=bind:NodeList 只允許從指定的鏈表分配
80 mpol=interleave 傾向於依次從每個節點分配
81 mpol=interleave:NodeList 依次從每個節點分配
82 mpol=local 優先本地節點分配內存
86 分隔符的十進制數來表示。例如，mpol=bind0-3,5,7,9-15
104 例如，mpol=bind=staticNodeList相當於MPOL_BIND|MPOL_F_STATIC_NODES的分配策略
