| Abstract: | This paper describes a method of designing and implementing a multiprocessor UNIX
file system based on modified Dijkstra's semaphore,which can provide two levels of concurrent and
exclusive access to the flie:one based on the buffer level and the other based on the file body so as
to achieve better parallel access to a multiprocessor file system.The model,structure and characters of
the multiprocessor UNIX file system,are presented with emphasis on the principal data structure:low
level buffer data structure and other internal data structures,and their management.Finally,data con-
sistence in a multiprocessor environment is also discussed |
