  • Method and system for file access using a shared memory
    Patent number: 7757049
    Abstract: A method for processing using a shared file that includes allocating a first working buffer between the shared file and a plurality of address spaces, wherein each of the plurality of address spaces is associated with one of a plurality of processors, copying first data from the shared file to the first working buffer by a first aggregator copying the first data from the first working buffer to the plurality of address spaces by the first aggregator, processing the first data, in parallel, by the plurality of processors to obtain a result, wherein the plurality of processors access data from the plurality of address spaces, and storing the result in the shared memory.
    Type: Grant
    Filed: November 17, 2006
    Date of Patent: July 13, 2010
    Assignee: Oracle America, Inc.
    Inventors: Andrew B. Hastings, Anton B. Rang, Alok N. Choudhary
  • Method and system for collective file access using an mmap (memory-mapped file)
    Patent number: 7647471
    Abstract: A method for processing using a shared file that includes creating a plurality of mmaps between a shared file and a plurality of address spaces, wherein each of the plurality of mmaps maps at least a portion of the shared file to one of the plurality of address spaces, and wherein each of the plurality of address spaces is associated with one of a plurality of processors, transferring, in parallel, data between the shared file and the address spaces using the plurality of mmaps associated with the plurality of address spaces, processing the data in parallel by the plurality of processors to obtain a result, wherein the plurality of processors access data from the plurality of address spaces, and storing the result in the shared memory.
