  • Patent number: 10235182
    Abstract: Embodiments described herein provide a system for facilitating hybrid task management across a central processing unit (CPU) and a graphics processing unit (GPU) of a computer. During operation, the system determines a set of tasks for performing data mining on a data set and storing the set of tasks in a data structure in an ascending order of uniformity associated with a respective task. The uniformity of a task indicates how uneven and skewed the task is compared to other tasks in the set of tasks. The system then allocates a subset of tasks to a core of the CPU from a front of the data structure and a subset of tasks to a core of the GPU from a back of the data structure.

  • Patent number: 10217241
    Abstract: Embodiments of the present invention provide a system for fast parallel graph compression based on identifying a set of large cliques, which is used to encode the graph. The system provides both permanently-stored and in-memory graph encoding and reduces the space needed to represent and store a graph, the I/O traffic to use the graph, and the computation needed to perform algorithms involving the graph. The system thereby improves computing technology and graph computation. During operation, the system obtains data indicating vertices and edges of a graph. The system executes a clique-finding method to identify a maximum clique in the graph. The system then removes the clique from the graph, adds the clique to a set of found cliques, and generates a compressed representation of the graph based on the set of found cliques.

  • Patent number: 10202990
    Abstract: A stress-engineered frangible structure includes multiple discrete glass members interconnected by inter-structure bonds to form a complex structural shape. Each glass member includes strengthened (i.e., by way of stress-engineering) glass material portions that are configured to transmit propagating fracture forces throughout the glass member. Each inter-structure bond includes a bonding member (e.g., glass-frit or adhesive) connected to weaker (e.g., untreated, unstrengthened, etched, or thinner) glass member region(s) disposed on one or both interconnected glass members that function to reliably transfer propagating fracture forces from one glass member to other glass member. An optional trigger mechanism generates an initial fracture force in a first (most-upstream) glass member, and the resulting propagating fracture forces are transferred by way of inter-structure bonds to all downstream glass members.
