  • Dynamically sizing a collaboration of concurrent computing workers based on user inputs
    Patent number: 7765561
    Abstract: A dynamic collaboration of processes in a concurrent computing environment is disclosed. A user can modify the size of collaboration or the number of processes that execute a computational job after the processes have been launched on the concurrent computing environment. A launched or running process can establish a communication channel with other processes in the collaboration so that the launched or running process can join the collaboration to execute the job. The user can also release a process from the collaboration so the released process can join a new collaboration to execute a different job. Once a job is completed, the processes can leave the collaboration, and the processes are then free to join a new collaboration subsequently.

  • MULTI-THREADED SUBGRAPH EXECUTION CONTROL IN A GRAPHICAL MODELING ENVIRONMENT
    Publication number: 20100175045
    Abstract: Exemplary embodiments support multi-threaded subgraph execution control within a graphical modeling or graphical programming environment. In an embodiment, a subgraph may be identified as a subset of blocks within a graphical model, or graphical program, or both. A subgraph initiator may explicitly execute the subgraph while maintaining data dependencies within the subgraph. Explicit signatures may be defined for the subgraph initiator and the subgraph either graphically or textually. Execution control may be branched wherein the data dependencies within the subgraph are maintained. Execution control may be joined together wherein the data dependencies within the subgraph are maintained. Exemplary embodiments may allow subgraphs to execute on different threads within a graphical modeling or programming environment.

  • Dynamic licensing in a distributed system
    Patent number: 7752138
    Abstract: A method and system is disclosed for dynamic licensing of software products in a distributed system. A job is generated by a master (or client) and the tasks in the job are distributed to a cluster of workers for the distributed execution of the job. The tasks are distributed with information on the software products for which the master is licensed. The workers receive the tasks with the information on the software products for which the master is licensed. The workers dynamically provide licenses for the software products which the master is licensed for. The workers execute the tasks using the dynamically provided licenses for the software products. The results from the execution of the tasks are returned to the client.
