Hi All During some readings, I remembered the eternal debatable Question when creating SMP VM (VM with many vCPUs): “Which is better: many Cores in a single socket or many Sockets each with single core..??” I remember how many times I debated for hours with my technical manager -while reviewing some designs- about the same question, but neither of us could prove a bit. To answer this question, we have to review some concepts: NUMA CPU Configuration: Non Uniform Memory Access (NUMA) is a CPUs configuration, in which each CPU has some Memory DIMMs local and connected to it. Each CPU can access both its local memory DIMMs with lowest latency and the remote DIMMs with higher latency using Interconnecting […]
