multiCPU
MultiCPU refers to computer systems that employ more than one central processing unit (CPU). In such systems, multiple processors can execute instructions concurrently, increasing potential throughput for parallel workloads. The term typically applies to hardware configurations with multiple physical CPUs on the motherboard, as distinct from multi-core designs where a single CPU package contains several cores. It is also used to describe configurations that the operating system treats as separate processing resources.
Most multi-CPU systems use symmetric multiprocessing (SMP) or non-uniform memory access (NUMA). In SMP, CPUs share
Operating systems provide scheduling across CPUs, with features for CPU affinity, load balancing, interrupt distribution, and
MultiCPU configurations are common in servers, data centers, high-performance computing clusters, and virtualization hosts, where workloads
Challenges include design complexity, cache-coherence overhead, NUMA tuning requirements, power consumption, and higher cost. As hardware
