  • Suction Canister and Corresponding Systems and Methods
    Publication number: 20170209631
    Abstract: A canister lid (101) for a canister (102) includes an annular perimeter (103) surrounding an interior portion (104). Rather than completely surrounding the interior portion, the annular perimeter is instead interrupted by a suction conduit (112) defined by a suction conduit (112) separating a first lobe (117) and a second lobe (118). The suction conduit (112) intersects the annular perimeter such that the first lobe is disposed interior of the annular perimeter while the second lobe is disposed exterior to the annular perimeter. The canister lid can further include one or more ports (110,111) extending from the interior portion. A canister (102) can include a valve (401) and can optionally be coupled to a hub mount vacuum source (1200) or a hub mount stand (1800).

  • Generating approximate usage measurements for shared cache memory systems
    Patent number: 9697126
    Abstract: Generating approximate usage measurements for shared cache memory systems is disclosed. In one aspect, a cache memory system is provided. The cache memory system comprises a shared cache memory system. A subset of the shared cache memory system comprises a Quality of Service identifier (QoSID) tracking tag configured to store a QoSID tracking indicator for a QoS class. The shared cache memory system further comprises a cache controller configured to receive a memory access request comprising a QoSID, and is configured to access a cache line corresponding to the memory access request. The cache controller is also configured to determine whether the QoSID of the memory access request corresponds to a cache line assigned to the QoSID. If so, the cache controller is additionally configured to update the QoSID tracking tag.

  • Providing shared cache memory allocation control in shared cache memory systems
    Patent number: 9678875
    Abstract: Providing shared cache memory allocation control in shared cached memory systems is disclosed. In one aspect, a cache controller of a shared cache memory system comprising a plurality of cache lines is provided. The cache controller comprises a cache allocation circuit providing a minimum mapping bitmask for mapping a Quality of Service (QoS) class to a minimum partition of the cache lines, and a maximum mapping bitmask for mapping the QoS class to a maximum partition of the cache lines. The cache allocation circuit receives a memory access request comprising a QoS identifier (QoSID) of the QoS class, and is configured to determine whether the memory access request corresponds to a cache line of the plurality of cache lines. If not, the cache allocation circuit selects, as a target partition, the minimum partition mapped to the QoS class or the maximum partition mapped to the QoS class.

  • METHOD TO ENFORCE PROPORTIONAL BANDWIDTH ALLOCATIONS FOR QUALITY OF SERVICE
    Publication number: 20170147249
    Abstract: Systems and methods relate to distributed allocation of bandwidth for accessing a shared memory. A memory controller which controls access to the shared memory, receives requests for bandwidth for accessing the shared memory from a plurality of requesting agents. The memory controller includes a saturation monitor to determine a saturation level of the bandwidth for accessing the shared memory. A request rate governor at each requesting agent determines a target request rate for the requesting agent based on the saturation level and a proportional bandwidth share allocated to the requesting agent, the proportional share based on a Quality of Service (QoS) class of the requesting agent.

  • METHOD AND APPARATUS FOR CACHE LINE DEDUPLICATION VIA DATA MATCHING
    Publication number: 20170091117
    Abstract: A cache fill line is received, including an index, a thread identifier, and cache fill line data. The cache is probed, using the index and a different thread identifier, for a potential duplicate cache line. The potential duplicate cache line includes cache line data and the different thread identifier. Upon the cache fill line data matching the cache line data, duplication is identified. The potential duplicate cache line is set as a shared resident cache line, and the thread share permission tag is set to a permission state.

  • Hashing algorithm for network receive filtering
    Patent number: 9594842
    Abstract: Roughly described, a network interface device is assigned a maximum extent-of-search. A hash function is applied to the header information of each incoming packet, to generate a hash code for the packet. The hash code designates a particular subset of the table within which the particular header information should be found, and an iterative search is made within that subset. If the search locates a matching entry before the search limit is exceeded, then the incoming data packet is delivered to the receive queue identified in the matching entry. But if the search reaches the search limit before a matching entry is located, then device delivers the packet to a default queue, such as a kernel queue, in the host computer system. The kernel is then responsible for delivering the packet to the correct endpoint.

  • CACHE WAY PREDICTION USING PARTIAL TAGS
    Publication number: 20170060750
    Abstract: Method and apparatus for cache way prediction using a plurality of partial tags are provided. In a cache-block address comprising a plurality of sets and a plurality of ways or lines, one of the sets is selected for indexing, and a plurality of distinct partial tags are identified for the selected set. A determination is made as to whether a partial tag for a new line collides with any of the partial tags for current resident lines in the selected set. If the partial tag for the new line does not collide with any of the partial tags for the current resident lines, then there is no aliasing. If the partial tag for the new line collides with any of the partial tags for the current resident lines, then aliasing may be avoided by reading the full tag array and updating the partial tags.

  • Positive Locating Feature of OptiPort
    Publication number: 20160298404
    Abstract: A system and method for treating a portion of a wellbore that includes a bottom hole assembly (BHA) connected to a work string. The BHA includes a packing element movable between an unset position and a set position and a locator device movable between retracted position and expanded positions. The locator device may be a locator collet. The locator collet may be expanded by a cone movable with respect to the collet. The expanded locator device is configured to engage a profile in a ported tubular within the wellbore. The engagement between the locator device and the profile selectively prevents further movement of the BHA and provides an indication of the location the BHA. The packing element may then be actuated and the wellbore treated through a port in the ported tubular. The BHA may then be moved to a different ported housing to treat another portion of the wellbore.
