Resource sharing allows multiple processes to access and use the same shared resources, such as memory, processing power, or files. This can significantly improve system performance and resource utilization.
Bounded blocking is a technique used in resource sharing where processes are granted access to a shared resource for a limited period. This approach is used to ensure that the resource is used efficiently and prevents any conflicts or deadlocks between processes.
Here's how bounded blocking works:
A process submits a request to access a shared resource.
The resource manager checks the resource availability and grants the request if sufficient free resources are available.
The process starts using the resource for the specified duration.
If the process finishes using the resource before the allotted time expires, it releases the resource and the process is removed from the waiting queue.
If the process does not finish using the resource, it is blocked and placed in a waiting queue.
Other processes can then be granted access to the resource until the blocked process finishes.
Benefits of bounded blocking:
Efficient resource utilization: processes only use the resource they need during the specified time.
Prevents conflicts and deadlocks: ensures that resources are used fairly and no one is starved.
Improves system performance: reduces waiting time for processes to acquire the resource.
Example:
Imagine a computer system with only 4 available CPU cores. Two processes, A and B, need to access the CPU simultaneously to complete their tasks. If they were granted full access to the CPU for their entire execution time, they would compete for the resource, leading to a deadlock.
Using bounded blocking for resource sharing ensures that each process gets 2 CPU cores for 10 units of time. This prevents one process from blocking the other and ensures that both tasks can be completed efficiently
