Tiling a primitive in a graphics processing system by edge-specific testing of a subset of tiles in a rendering space
In tile-based graphics processing systems, a tiling unit determines which tiles of a rendering space a primitive is in, such that the primitives in a tile can be rendered.Rather than performing tiling calculations for each tile in a bounding box for a primitive, tiling tests can be performed for a subset of the tiles. Then the results of the tiling tests for the subset of tiles can be used to determine whether the primitive is in other tiles which are located within a region bounded by two or more of the tiles of the subset. In this way the tiling process can be implemented without performing tiling calculations for all of the tiles in the bounding box for a primitive. Reducing the number of tiling calculations can help to improve the efficiency of the graphics processing system (in terms of speed and power consumption) for rendering a primitive. |

Individual use code for multiple users in a loyalty program
A single code can be used only one time by each of multiple users. A user visits a merchant location and wants to sign up for a loyalty program. The merchant issues the user a one-time code, such as a QR code. The user connects to a loyalty program system to download the loyalty application. The user downloads the loyalty application and enters the code into the application. The user receives a “punch” for the loyalty program based on the code. The server operating on the loyalty program system verifies that the punch created is the first and only punch created by the one-time code. If the code has been previously used for the particular user, the server does not create an additional punch. |

By executing a probability model, a first probability of adverse impact corresponding to a first vulnerability in the set of vulnerabilities is computed. The first vulnerability and the first probability of adverse impact are added to a vulnerability repository. Using the first probability of adverse impact and a second probability of adverse impact, a first cumulative probability of adverse impact is calculated. Using the first cumulative probability and a first level of organizational impact corresponding to the application, a first risk category is assigned to the application. Responsive to the first risk category being lower than a second risk category, a system management application is caused to install the application in the computer system. |

Fast graph query engine optimized for typical real-world graph instances whose small portion of vertices have extremely large degree
Techniques herein accelerate graph querying by caching neighbor vertices (NVs) of super-node vertices. In an embodiment, a computer receives a graph query (GQ) to extract result paths from a graph in a database. The GQ has a sequence of query vertices (QVs) and a sequence of query edges (QEs).

Traversing each QE and QV entails retrieving NVs of a current graph vertex (CGV) of a current traversal path. If the CGV is a key in a cache whose keys are graph vertices having an excessive degree, then the computer retrieves NVs from the cache. Otherwise, the computer retrieves NVs from the database. If the degree is excessive, and the CGV is not a key in the cache, then the computer stores, into the cache, the CGV as a key for the NVs. |

An automatic video tagging system which learns from videos, their web context and comments shared on social networks is described. Massive multimedia collections are analyzed by Internet crawling and a knowledge base is maintained that updates in real time with no need of human supervision.

To create this dataset that evolves in real-time and uses labels that are relevant to the users, a weakly-supervised deep learning approach is utilized combining both a machine-learning pre-processing stage together with a set of keywords obtained from the internet. The resulting tags combined with videos and summaries of videos are used with deep learning to train a neural network in an unsupervised manner that allows the tagging system to go from an image to a set of tags for the image and then to the visual representation of a tag. |

Low latency fetch circuitry for compute kernels
Techniques are disclosed relating to fetching items from a compute command stream that includes compute kernels. In some embodiments, stream fetch circuitry sequentially pre-fetches items from the stream and stores them in a buffer. In some embodiments, fetch parse circuitry iterate through items in the buffer using a fetch parse pointer to detect indirect-data-access items and/or redirect items in the buffer. The fetch parse circuitry may send detected indirect data accesses to indirect-fetch circuitry, which may buffer requests. In some embodiments, execute parse circuitry iterates through items in the buffer using an execute parse pointer (e.g., which may trail the fetch parse pointer) and outputs both item data from the buffer and indirect-fetch results from indirect-fetch circuitry for execution. In various embodiments, the disclosed techniques may reduce fetch latency for compute kernels. |

Graph-based vectorization for software code optimizations
A software code optimizer automatically detects inefficiencies in software code and corrects them. Generally, the software code optimizer converts software code into a graph representing the workflows and relationships in the software code. The graph is then converted into vectors that represent each workflow in the software code. The vectors are assembled into a matrix that represents the software code. The matrix may be stored in a cluster in a database as an example of optimized software code or be compared with other matrices stored as clusters in the database to determine whether the software code is optimized. The software code optimizer can change the software code to be more efficient if a matrix for an optimized version of the software code is found in the database. |

Deserialization of stream objects using constant-foldable method handles
A data-instantiator method handle is configured to create a target object based on a stream object. One type of data-instantiator method handles is a Stream Object Processor method handle (SOP_mh). A SOP_mh is a runtime-computed constant in a runtime constant pool. A runtime environment resolves the SOP_mh lazily responsive to a request to access the SOP_mh. The runtime environment invokes the SOP_mh to create a target object based on a stream object. By virtue of being a constant in the runtime constant pool, the SOP_mh is a candidate for optimization by a dynamic compiler in the runtime environment. The dynamic compiler may elect to constant fold the value of the SOP_mh and inline any code or executable logic that the SOP_mh refers to. |
