31. Message passing can be efficiently implemented via symmetric multiprocessing , with or without shared memory cache coherence. 32. Additionally, it allows multiprocessing programming by means of OpenMP, in order to increase computer performance. 33. Initially, multiprocessing was built using multiple discrete CPUs and boards to implement the interconnect between the processors. 34. Because multiprocessing systems can execute instructions simultaneously, they offer greater processing power than single-processing system. 35. The Coppermine T also had two way symmetrical multiprocessing capabilities, but only in FC-PGA2 boards. 36. Together with Pyramid Technology and Sequent Computer Systems, Alliant's machines pioneered the symmetric multiprocessing market. 37. One of the problems with the Cray-2 had been poor multiprocessing performance due to limited GFLOPS. 38. One technique of how this parallelism is achieved is through multiprocessing systems, computer systems with multiple CPUs. 39. The system interface controller supported glue-less symmetrical multiprocessing ( SMP ) of up to four microprocessors. 40. ;Symmetry S16 : The S16 was the entry-level multiprocessing model, which ran DYNIX / ptx.
