Abstract
In connection with an access of content from a cache, a snoop request can be sent to one or more remote cache devices to determine if any other cache has a copy of the content. A link between the cache and the remote cache devices can include a snoop bypass device. The snoop bypass device can monitor content cached by the one or more remote devices on a cache line or coarser granularity. The snoop bypass device can respond to the snoop request with a negative indication based on a coarser granularity tracking of content of the one or more remote cache devices.
