1. A method for the implementation of simultaneous, non-contentious file access by multiple threads or processes using distributed buffered file input/output on an underlying network of symmetric multiprocessing (SMP) nodes, comprising:

  • performing all direct file reads and writes from the head node of the network of SMP nodes;

    maintaining a pool of buffers in the head node to store pending write buffers;

    extending buffered file read/write access to threads running in the head node or non-head nodes through the use of messages exchanged between the head node and other nodes; and

    providing non-blocking file writes that are guaranteed atomic up to the maximum buffer size, and that eliminate the need for locking.
