  • Patent number: 8132172
    Abstract: A thread scheduler may be used in a chip multiprocessor or symmetric multiprocessor system to schedule threads to processors. The scheduler may determine the bandwidth utilization of the two threads in combination and whether that utilization exceeds the threshold value. If so, the threads may be scheduled on different processor clusters that do not have the same paths between the common memory and the processors. If not, then the threads may be allocated on the same processor cluster that shares cache among processors.

  • Patent number: 7584408
    Abstract: Methods, systems, and apparatus are provided to generate a Viterbi path for a DBN. The DBN is converted to a chain of junction trees, where each tree represents a decision-making process. The trees are forwardly iterated and the Viterbi path is generated during the forward iteration (forward pass). This is achieved by maintaining backpointers to previously processed junction trees during the forward pass and dynamically assembling the Viterbi with each pair of junction trees during the forward pass.
