What is the main purpose of open NUMA functions?

The main purpose of open NUMA (Non-Uniform Memory Access) functions is to optimize memory access performance for the virtual machine. In a NUMA architecture, memory access times can vary depending on the memory controller's proximity to the CPU that is requesting the data. By leveraging open NUMA functions, systems can optimize memory allocation and access patterns based on the topology of the hardware. This means that virtual machines can be configured to utilize memory that is directly connected to their assigned CPUs, reducing latency and increasing the speed of memory access.

This optimization process helps to ensure that a virtual machine runs more efficiently by taking full advantage of the underlying physical infrastructure. As a result, applications running on virtual machines can experience improved performance, particularly in memory-intensive workloads, which is crucial for the overall effectiveness of cloud computing environments where resources are often shared among multiple virtual instances.
