The playground has been completed but is still undedicated. 操场已经建成了,但仍旧不是专用的。
According to resource performance deviation rates, the hosts in an undedicated cluster can compose some pseudo-clusters so that resource performances are close to each other in an identical pseudo-cluster. 非专用机群中的主机可根据资源性能偏差率构造出若干伪机群,使同一个伪机群中的资源性能彼此相近。
