  • Database calculation using parallel-computation in a directed acyclic graph
    Patent number: 9576072
    Abstract: Disclosed herein are technologies related to database calculation that utilizes parallel-computation of tasks in a directed acyclic graph. In accordance with one aspect, dependency of tasks is converted into a directed acyclic graph that topologically orders the tasks into layers of tasks. A database calculation may be performed, wherein the database calculation computes in parallel the tasks in each layer of the layers of tasks.
    Type: Grant
