Rl /11...... 7 Simple window manager 38 Concepts of Operating Systems In the case of an operating system such as UNIX, it would seem logical that very little of the window management would be in the operating system kernel. However, because of the inadequate inter-process communication mechanisms and susceptibility to delays in scheduling under heavy load, that system would be unlikely to offer fast enough feedback for a good user interface. Although it appears attractive to build applications out of a large number of cooperating processes, programs are either in user space and find it hard to communicate with each other, or they are in the kernel in which case they are hard to program and debug.
It would be better if implicit parallelism could be achieved, whereby the intrinsic parallelism could be detected and exploited by the compilers, operating systems and computer hardware. 8 Some multiprocessing system structure designs In terms of operating systems for multiprocessor systems, several types of system exist. Three are outlined in this section, namely, master-slave, separate executives and symmetrical systems. 1 Master-slave In the master-slave configuration one of the processors is designated the master.
A file system is an essential requirement of this system as it is infeasible to input a large document via the input device every time a job is run. This was not the case with the simple spooling system, where large decks of cards could be submitted on every run of a program. However, it is clearly impractical for a user sitting at a terminal to do likewise. Although it would be possible to integrate the functions of a file manager within the disk manager, logically they are quite different and so it is better to regard them as being in separate modules of the system.
