  • Electronic data file access management in a distributed computer system
    Patent number: 12056398
    Abstract: An electronic data file management system may comprise storage nodes containing memory devices coupled through a network to compute nodes configured to request group access to a file on the storage nodes, the request being made by at least two processes running on the compute nodes. At least one of the compute nodes is configured to determine the type of a memory device that includes the file, cause the plurality of compute nodes to collectively access the file in a first access mode, applying a write lock mechanism and disabling a collective buffering mechanism to each of the different ones of the compute nodes if the memory device is a first type, and access the file in a second access mode, applying the write lock mechanism and enabling a collective buffering mechanism to each of the different ones of the compute nodes, if the memory device is a second type.
