Maximizing HPC application performance on Intel Xeon Scalable Processors requires a thoughtful approach to process placement on this new architecture. Here, we outline our implementation of it on Azure HC-series VMs for HPC applications. We will use the term “pNUMA” to refer to a physical NUMA domain, and “vNUMA” to refer to a virtualized NUMA domain. Similarly, we will use the term “pCore” to refer to physical CPU cores, and “vCore” to refer to virtualized CPU cores.

Physically, an [HC-series](hc-series.md) server is 2 * 24-core Intel Xeon Platinum 8168 CPUs for a total of 48 physical cores. Each CPU is a single pNUMA domain, and has unified access to six channels of DRAM. Intel Xeon Platinum CPUs feature a 4x larger L2 cache than in prior generations (256 KB/core -> 1 MB/core), while also reducing the L3 cache compared to prior Intel CPUs (2.5 MB/core -> 1.375 MB/core).
