  • Patent number: 11656920
    Abstract: A processing unit generates, in the initial setting of all-to-all communication between processes, a unique node-order process number for each process on the basis of hardware information, computes the virtual rank number of each process on the basis of the node-order process number of the process, and stores the computed virtual rank numbers in a storage unit. When performing the al-to-all communication between the processes, the processing unit determines the communication partner process of each process for the current step in the all-to-all communication by performing an exclusive OR operation between the virtual rank number of the process, stored in, the storage unit, and the step number of the current step. Then, the processing unit performs communication from each process to the corresponding communication partner process.

  • Publication number: 20230153021
    Abstract: A memory management unit includes a controller performing a process translating a requested virtual address to a physical address based on a first region storing first entries indicating the physical address matching a given bit range of the virtual address and a second region storing a second entry associating the bit range with the first entries. When a second entry matching the bit range of a first address is hit in the second region, the controller sets, in the hit second entry, an identification number of a first entry specified by the first address. When the same second entry regarding the first address and a second address is hit and when an identification number specified by the second address is larger than an identification number set in the second entry, the controller obtains, from a memory, information of first entries subsequent to first entries associated with the hit second entry.

  • Publication number: 20230153647
    Abstract: In an embodiment, each of a set of subgraphs associating an entity from an entity graph with an item is extracted from a graph database. A label score, which is an importance of an item to a respective entity is computed for each subgraph. A training dataset including the set of subgraphs and the label score for each subgraph is generated. A set of ML regression models is trained on respective entity-specific subsets of the training dataset. An ML regression model associated with a second entity generates a prediction score for an unseen graph. From the set of subgraphs, one or more subgraphs associated with the second entity are determined based on the prediction score. A recommendation for one or more items is determined, based on the one or more subgraphs. The recommendation is displayed on a user device of the first entity.
