Visualize OS Resource Allocation

The Deadlock Simulator is a powerful educational tool designed specifically for Operating Systems students, educators, and software engineers. It bridges the gap between theoretical textbook concepts and practical, visual understanding.

Instead of manually crunching numbers on paper to find out if a system will deadlock, you can input your own Allocation, Max Demand, and Available Resources matrices.

The tool dynamically generates a Force-Directed Resource Allocation Graph, visually connecting processes to their held and requested resources. It provides a real-time, step-by-step breakdown of how the operating system evaluates resource requests.

The Banker's Algorithm Explained

Developed by Edsger Dijkstra in 1965, the Banker's Algorithm is a strategy used by operating systems to safely allocate resources without falling into a deadlock.

It gets its name from a banking analogy: A bank (the OS) has a finite amount of cash (resources). It has several customers (processes) who have a credit limit (max demand). The bank must ensure that it never lends out money in such a way that it can't satisfy the maximum needs of at least one customer.

Before granting a process's request, the algorithm simulates the allocation and checks if the system remains in a Safe State. A state is safe if there is a sequence of processes where each can receive its required resources, finish its execution, and return the resources to the pool, guaranteeing no deadlocks occur.
