Question

Discuss the problems that could emanate in a multi-processing environment where resources are shared by many processors and how can the problem be reduced nor eliminated.

Answer 1

Answer)
Multiprocessing is the ability of the computer to process more than one task simultaneously. All the modern computers mostly support multi-processing. Also, in a multi-processing environment where resources are to be shared by many processes, many issues crop up as the resources are limited and many processes can try to access the same resources and also at the same time. The problems which could crop up in such a multi-processing system are that, deadlocks can happen during the multi-processing of the share resources as a process may need 1 or more than 1 resources, and when a process needs many resources and does not get all resources to execute the task it is due to execute and also does not release the resources while other processes might be waiting for the same resources, then deadlock occurs. Deadlock is a never-ending loop. The problem can be reduced or eliminated using process synchronization and critical section problems where the process will share a resource when it needs it and will also release when it does not need it. Preemption of process resource allocations can also prevent the conditions for acquiring of deadlocks. Circular Wait should also be prevented. Hold and Wait should not happen for a resource by a process. Deadlock thus can be detected and mitigated using the best practices.
