之前发现Power7上使用分区服务器,CPU和内存亲和度问题,分区服务器性能会有较大波动,在power9上是否有优化提高?
收起POWER9 processor highlights
Here are some highlights of the POWER9 processor:
Four processor offerings available (SMT8 cores) and offered through both GAs:
– 12-core or 11-core processor (maximum throughput)
– 10-core processor
– 8-core processor (maximum core performance)
Processor frequencies dynamic for maximum performance
CoD support
Increased processor to processor fabric interconnect:
– 16 Gbps X-Bus Fully connected fabric within a central electronics complex drawer
– 4x increase in O-Bus fabric for Drawer to Drawer interconnect or Accelerator
