The SBC CNe is enhanced to allocate containers to vCPUs using non-integers (fractionally) when the containers do not require a full vCPU. The SBC CNe will increase the vCPU usage by 10% (for example, from 1 to 1.1) to optimize resource utilization for those containers that do not require full vCPUs. |
From the worker node, run the following command to view which CPUs are allocated to the containers that requested dedicated vCPUs.
