Abstract: Provided is a method of determining task scheduling probability. More specifically, the method includes establishing a set of task attributes. A database of prior task vectors in accordance with the set of task attributes then also provided, wherein each prior task vector representing a prior scheduled task. A new task is received having at least a subset of the task attributes. For this new task, a new task vector is generated based on the new task attributes. The new task vector is compared with the prior task vectors and the differences are recorded. The probability of successful scheduling is then evaluated based on the aggregate differences for each attribute. A system operable to perform the method is also provided.

Abstract: A distributed multimodal collaboration system includes at least one server coupled to a network, a plurality of data sources coupled to the network and a plurality of clients executing on a corresponding plurality of client workstations coupled to the network. The system further includes a tuple-space having a plurality of descriptors. The tuple-space is accessible by the plurality of data sources, and the plurality of clients, and a descriptor distribution and invalidation protocol is operative to distribute and invalidate descriptors accessible by the plurality of clients and the plurality of data sources, and the system includes a transaction processor for committing a plurality of transactions associated with the descriptor distribution and invalidation protocol.
