Multi Processors
The latest outcome of assorted chip multiprocessors needs a dissimilar operating system organization from the customary SMP architecture. Even though the SMP architecture has been extensively accepted in current multiprocessor operating systems, it is limited to consistent processors in connection to universal shared memory. However, the master-slave architecture has modest enslavement upon the important organizations of hardware thereby having great access of coping with heterogeneous multiprocessors. This encourages us to look keenly into the master slave approach. Therefore we will be able to solve recent and performance problems that come up as a result or in connection to master-slave approach by first understanding the preceding design of a master-piece architecture known as APRIX then come up with a modification of communication mechanism between the master and slave, this allows the master to give priority-based system call services to slave kernels and also modify the multiprocessing performance as a whole.
To compile a symmetric processing or SMP, include a multiprocessor or computer architecture where more than one similar processors can merge to link to a single shared main memory. The commonly known multiprocessor system in recent days uses SMP architecture. Multi-core processor, the SMP architecture can be termed as the core defining them as two different processors. SMP systems allow all the processors to undertake all tasks without considering the location of the memory, when standardized operating systems support. SMP system can in a very simple way relocate tasks between the processors t enhance the balancing and efficiency of workload. SMP can...

SMP is said to be simple as well as universal in that it does not in any way inflict limitations on the model of programming used to come up with the appendix. The model of corresponding divisions is frequently in use. At the time each and every processors is engaged completely separately from each other, on the other hand, it is doable to establish and the models by the use of an inter-processor exchange. The use of universal memory enhances momentum of such switch over; it also allows user to access all the memory size at once. SMP also gives room for effective mode of automatic deparalleling. SMP is also effortlessness in operation and as a principal, the use of air conditioning system is evident and this facilitates the maintenance service. It is also pocket friendly.
According to K.Ekanadham, B-H. Lim, P. Pattnaik and M. Snir. (1998), a situation of symmetrical multiprocessing in reference to software we mean the opposite of master-slave multiprocessing (MSMP) architecture. In relating to the initial stage system, a SMP machine is in a position to do all tasks on any of the available processors. Due to the fact that SMP system lacking master or slave processors all the sensible units are able to finish the required task. In case of an master-slave multiprocessing (MSMP) architecture system a particular processor may be unable to clear a particular task due to factors such as lack of ability to get access on the entire memory map, special purpose nature of the processor) like…
