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.
