Distributed Control Each node has the same responsibility for, and will expend the same amount of effort in detecting deadlock –The WFG becomes an abstraction, with any single node knowing just some small part of it –Generally detection is launched from a site when some thread at that site has been waiting for a long time in a resource request message 65 Tulika Ringan (AL_IT)
{"Image DocumentName": "Distributed Control Models", "Image ImageDescription": "Four common models are used in building distributed deadlock control algorithms: Path-pushing. path info sent from waiting node to blocking node. Edge-chasing. probe messages are sent along graph edges. Diffusion computation. echo messages are sent along graph edges. Global state detection. sweep-out, sweep-in WFG construction and reduction.
