1 Your PC's Performance Features Advantages of Dual Processor Configurations MPS-Ready Operating Systems An MPS-ready operating system is multithreaded and also guarantees the integrity of any data shared between the different processors. Data integrity is essential in any environment where multiple copies of the same data can exist - failure to guarantee this can lead to logical conflicts and operational failure. MPS-ready operating systems protect against these risks by ensuring that valid copies of the same data are identical. MultiprocessorEfficient Operating Systems Some advanced operating systems are more than MPS-ready. They are also multiprocessor-efficient. These operating systems gain maximum advantage from multiple processors. Windows NT is an example of a multiprocessor-efficient operating system. Multiprocessor-efficient operating systems reduce the length of the individual functions contained within their different threads. In an MPS-compliant multiprocessing computer, all processors share the same local bus and must load the functions they perform over this bus. By reducing the length of these functions, a multiprocessor-efficient operating system ensures that no processor is slowed while another processor loads a function over the local bus. This guarantees that each processor is used to its best advantage. Multithreaded Applications Applications written specifically for multithreaded operating systems are also multithreaded. These applications permit their own operation to be performed through separate threads. Refer to the manual supplied with your software application to determine if it is multithreaded. 10 English
