T9000 Transputer, a complex superscalar pipelined processor designed to support large-scale multiprocessing. NUMA architectures logically follow in scaling from symmetric multiprocessing (SMP) architectures. The term "multiprocessor" can be confused with the term "multiprocessing". The kernel schedules multiprocessing tasks using a preemptive scheduling algorithm. Neutrino supports symmetric multiprocessing and processor affinity, called bound multiprocessing (BMP) in QNX terminology. TuxOnIce provides advantages such as support for symmetric multiprocessing and preemption. The PowerPC 604e was the first Mac processor available in a symmetric multiprocessing (SMP) configuration. Also PF supports SMP (Symmetric multiprocessing) & STO (Stateful Tracking Options). The system interface controller supports glue-less symmetrical multiprocessing (SMP) of up to four microprocessors. This release included internationalization and localization and support for symmetric multiprocessing systems. Each CPU in a symmetric multiprocessing arrangement needs to be updated individually. Variable Symmetric Multiprocessing (vSMP) is a specific mobile use case technology initiated by NVIDIA. This has already yielded separate, complementary standards for symmetric multiprocessing, namely OpenMP. TSS/360 was one of the first implementations of tightly-coupled symmetric multiprocessing.
