  • Learning-based workload resource optimization for database management systems
    Patent number: 11500830
    Abstract: A DBMS training subsystem trains a DBMS workload-manager model with training data identifying resources used to execute previous DBMS data-access requests. The subsystem integrates each request's high-level features and compile-time operations into a vector and clusters similar vectors into templates. The requests are divided into workloads each represented by a training histogram that describes the distribution of templates associated with the workload and identifies the total amounts and types of resources consumed when executing the entire workload.
    Type: Grant
    Filed: October 15, 2020
    Date of Patent: November 15, 2022
    Assignee: International Business Machines Corporation

  • Systems and methods for sustainability and social interaction analysis in building information modeling
    Patent number: 11270036
    Abstract: Described herein are systems and methods for building information modeling. An embodiment of the method includes: receiving a BIM; and transforming the BIM to flatten solid-volume geometry for space bounding elements into thin-walled boundaries of the thermal zones by: determining wall volumes from the BIM; collapsing the wall volumes to provide single surface walls; determining wall center surfaces and end points from the single surface walls; aligning, and trimming or extending, the single surface walls using the wall end points to create closed spaces; connecting the closed spaces vertically to generate a single water tight volume for the closed spaces; and creating interfaces between the single water tight volume for the closed spaces to generate thermal zones.
