A polynomial-time test for the deadlock-freedom of computer systems
- 135 Downloads
We call a system of n processes sharing m reusable resources deadlock-free, if and only if the allocation policy which automatically grants any request that can be granted with currently free resource units never leads to a deadlock. The best known test for deadlock-freedom is essentially enumerative. We present a test employing a network-flow technique, which works in time bounded by O(n3m).
