  • Method and apparatus for avoiding read-after-write hazards in an execute-ahead processor
    Patent number: 7263603
    Abstract: One embodiment of the present invention provides a system that avoids read-after-write (RAW) hazards while speculatively executing instructions on a processor. The system starts in a normal execution mode, wherein the system issues instructions for execution in program order. Upon encountering a stall condition during execution of an instruction, the system generates a checkpoint, and executes the instruction and subsequent instructions in a speculative-execution mode. The system also maintains dependency information for each register indicating whether or not a value in the register depends on an unresolved data-dependency. The system uses this dependency information to avoid RAW hazards during the speculative-execution mode.

  • Decentralized peer-to-peer advertisement
    Patent number: 7263560
    Abstract: Embodiments of a shared resource distributed index mechanism that peers in a peer-to-peer network may utilize to distribute index entries corresponding to resources to indexes of shared resources among one or more other peers. These indexes may be used to direct queries to peers where the queries are most likely to be answered. When a query is received by a rendezvous peer including one or more indexes, contents of the query may be “looked up” in the index to find matches. The results of the lookup may include information on one or peer(s) that may hold advertisement(s) to the resource requested by the query. The query may then be forwarded to one or more peers that may hold the advertisement for the resource. Embodiments may provide “loosely-coupled” distribution of index entries for use in querying for resources in the peer-to-peer network.

  • Implementing a distributed file system that can use direct connections from client to disk
    Patent number: 7260576
    Abstract: One embodiment of the present invention provides a distributed file system that is able to use direct connections between clients and disks to perform file system operations. Upon receiving a request at a client to access a file, the client performs a lookup in a local cache to determine what physical disk blocks are associated with the request. If the lookup cannot be satisfied from the local cache, the client forwards the request to a server. In response to the forwarded request, the client receives a block map for the file from the server. This block map includes location information specifying physical disk blocks containing the file. The client uses this block map to determine which physical disk blocks are involved in the request and then accesses the file directly from the disk without going through the server.
