  • System and method for scheduling and executing data transfers over a network
    Patent number: 7065586
    Abstract: A system and method for scheduling transfers of data through a network, the system comprising a transfer module at each node in the network, the transfer module being configured to schedule data transfers according to available resources at each node. In one embodiment, the transfer module includes a scheduling module, a routing module, and an execution module. The scheduling module at each node evaluates a single hop request in view of objectives, such as a deadline, and the available resources at that node, for example transmit bandwidth, receive bandwidth, and storage space, all of which may change as a function of time.

  • System and method for automated and optimized file transfers among devices in a network
    Publication number: 20050273514
    Abstract: A system for automated and optimized file transfers among devices in a network comprises a client configured to request a file transfer, a server configured to transfer the requested file to the client, and a scheduling module configured to schedule delivery of the file to the client. The scheduling module preferably schedules the delivery of the file to be completed by a deadline. In an alternate embodiment, the file is transferred to a device in the network that did not send the request. The file transfer may be requested by a user at the client or may be requested by a pre-fetch module of the client.

  • Compilation using two-colored pebbling register allocation method such that spill code amount is invariant with basic block's textual ordering
    Patent number: 4782444
    Abstract: A method for allocating and optimizing register assignments during compiling of source into executable code in either a scalar or vector processor uses a pebble game heuristic played on each basic block dependency graph for local optimization. Like variable analysis and loop unrolling are used for global optimization.
