Latest Patents

One of Rajnish Ghughal's latest patents is focused on speculative distributed conflict resolution for a cache coherency protocol. This conflict resolution technique ensures that all conflicts can be detected by at least one of the conflicting requestors if each node monitors all requests after that node has made its own request. If a line is in the Exclusive, Modified, or Forward state, conflicts are resolved at the node holding the unique copy. The winner of the conflict resolution, along with possibly the losers, reports the conflict to the home node. This node pairs conflict reports and issues forwarding instructions to ensure that all requesting nodes eventually receive the requested data. If a requested cache line is either uncached or present only in the Shared state, the home node provides a copy of the cache node and resolves conflicts. In one embodiment, a blackout period after all responses until an acknowledgment message has been received allows all conflicting nodes to be aware of conflicts in which they are involved.
