  • Publication number: 20190212797
    Abstract: A persistent memory storage system and method of operating. The storage system is embodied as memory module (e.g., a DIMM or PCIe card) in a host server and accessible via a first access path to/from the memory module. After a power failure at the host server, any authorized device, e.g., a second server, is configured to access and extract the retained memory at the failed host server via a secondary network-based access path (e.g., Ethernet connection). Power may be supplied to the memory module of the failed host server via a Power-over-Ethernet switch to support the secondary access path. A Power-over-Ethernet (PoE) switch may provide the necessary power to the memory module when power is unavailable from the host server and when any temporary power source is exhausted. A redundant power source and/or backup battery may supply the PoE switch. Such power sources and/or batteries can thereby provide backup power.

  • Publication number: 20190188074
    Abstract: An embodiment includes a method for use in operating a memory chip, the method comprising: operating the memory chip with an increased burst length relative to a standard burst length of the memory chip; and using the increased burst length to access metadata during a given operation of the memory chip. Another embodiment includes a memory module, comprising a plurality of memory chips, each memory chip being operable with an increased burst length relative to a standard burst length of the memory chip, the increased burst length being used to access metadata during a given operation of the memory module.

  • Patent number: 10324491
    Abstract: A time of day (TOD) synchronization mechanism in a first processor transmits a latency measure message simultaneously on two links to a second processor. In response, the receiver in the second processor detects latency differential between the two links, detects the delay in the second processor, and sends the latency differential and delay to the first processor on one of the two links. The first processor stores TOD delay values in the two links that account for the latency differential between the two links. When a TOD message needs to be sent, a link loads a counter with its stored TOD delay value, then decrements the counter until the TOD message is ready to be sent. The resulting counter value is the receiver delay value, which is transmitted to the receiver as data in the TOD message, thereby reducing TOD jitter between the two links.

  • Publication number: 20190179862
    Abstract: A method and apparatus are provided for automatically generating and processing first and second concept vector sets extracted, respectively, from a first set of concept sequences and from a second, temporally separated, concept sequences by performing a natural language processing (NLP) analysis of the first concept vector set and second concept vector set to detect changes in the corpus over time by identifying changes for one or more concepts included in the first and/or second set of concept sequences.

  • Patent number: 10310812
    Abstract: Mechanisms are provided for performing a matrix operation. A processor of a data processing system is configured to perform cluster-based matrix reordering of an input matrix. An input matrix, which comprises nodes associated with elements of the matrix, is received. The nodes are clustered into clusters based on numbers of connections with other nodes within and between the clusters, and the clusters are ordered by minimizing a total length of cross cluster connections between nodes of the clusters, to thereby generate a reordered matrix. A lookup table is generated identifying new locations of nodes of the input matrix, in the reordered matrix. A matrix operation is then performed based on the reordered matrix and the lookup table.

  • Publication number: 20190155830
    Abstract: Generating, updating, and using a knowledge graph. Concepts in a knowledge graph can have relations to one another. These relations may be expressed as confidence values. A training data set may be split into two portions, with the first portion used to update confidence values for existing relations between concept pairs, using the knowledge graph. These confidence values can be used, together with the second portion used to update confidence values for known phrases that express known relations. These confidence values, in turn, can be used, together with the first portion, to increase the accuracy of the original confidence scores with respect to existing relations. The process may be iteratively employed, with each iteration increasing the accuracy of confidence scores.

  • Publication number: 20190073414
    Abstract: According to an aspect, automatically linking text to concepts in a knowledge base using differential analysis includes receiving a text string and selecting, based on contents of the text string, a plurality of data sources that correspond to concepts in the knowledge base. In a further aspect, automatically linking the text to the concepts includes calculating, for each of the selected data sources, a probability that the text string is output by a language model built using the selected data source, calculating a probability that the text string is output by a generic language model, calculating link confidence scores for each concept based on a differential analysis of the probabilities, and creating a link from the text string to one of the concepts in the knowledge base. The creating is based on a link confidence score of the concept being more than a threshold value away from a prescribed threshold.
