Abstract: A method includes using at least one processor to receive image data including one or more virtual objects and determining a distance between a user extremity and the one or more virtual objects based on the image data. Further, the method includes detecting a first gesture of the user extremity based on the image data and generating a virtual sphere within a virtual object of the one or more virtual objects. The method also includes determining that the distance is less than a threshold, detecting movement of the user extremity based on the image data, and adjusting a position of the virtual object based on the movement of the user extremity.

Abstract: A multiprocessor computer system comprises a first node operable to access memory local to a remote node by receiving a virtual memory address from a requesting entity in node logic in the first node. The first node creates a network address from the virtual address received in the node logic, where the network address is in a larger address space than the virtual memory address, and sends a fast memory access request from the first node to a network node identified in the network address.

Abstract: An improved method for the prevention of deadlock in a massively parallel processor (MPP) system wherein, prior to a process sending messages to another process running on a remote processor, the process allocates space in a deadlock-avoidance FIFO. The allocated space provides a “landing zone” for requests that the software process (the application software) will subsequently issue using a remote-memory-access function. In some embodiments, the deadlock-avoidance (DLA) function provides two different deadlock-avoidance schemes: controlled discard and persistent reservation. In some embodiments, the software process determines which scheme will be used at the time the space is allocated.
