A message flow controller limits a process from passing a new message in a reliable message passing layer from a source node to at least one destination node while a total number of in-flight messages for the process meets a first level limit. The message flow controller limits the new message from passing from the source node to a particular destination node from among a plurality of destination nodes while a total number of in-flight messages to the particular destination node meets a second level limit. Responsive to the total number of in-flight messages to the particular destination node not meeting the second level limit, the message flow controller only sends a new packet from among at least one packet for the new message to the particular destination node while a total number of in-flight packets for the new message is less than a third level limit.

Flow control for reliable message passing

A mechanism is provided for sharing form data by users of a social network. A first value input for a first label by a first user is received. The first label is associated with a tag in a mapping table. The first value is associated with the tag in a first user table. The first value is recognized as input for a different label than the first label. The different label is associated with the tag in mapping table. A second value is received that is input for a second label by a second user. The second label is associated with the tag in the mapping table. The second value is associated with the tag in a second user table. The second value is recognized as input for a different label than the second label. The different label than the second label is associated with the tag in mapping table.

Sharing form training result utilizing a social network

A mechanism is provided for providing trustworthiness for users of a social network for web sites. The computer listens to web browsing activities of a user, and receives feedback from the user when web browsing by monitoring user actions. monitoring user actions includes monitoring the user searching a peer-to-peer environment and search results obtained, and in response to the user selecting a first link for the search results in the peer-to-peer environment, determining a score for the first link based on the user selecting a second link for the search results. The score for the first link is provided to the users of the social network.

A method, system, and computer program product are provided for managing a cache. A region to be stored within the cache is received. The cache includes multiple regions and each of the regions is defined by memory ranges having a starting index and an ending index. The region that has been received is stored in the cache in accordance with a cache invariant. The cache invariant guarantees that at any given point in time the regions in the cache are stored in a given order and none of the regions are completely contained within any other of the regions.
