A parallel virtual file system

摘要: A parallel virtual file system for processing systems including single-processor having multiple storage devices. The invention manages partitioned files as follows: (1) partitions of a are stored in set isomorphic "data trees"; (2) an additional directory tree, called the "control tree", is used to build model intended structure data trees; (3) combination control tree and collection trees referred "multifile system", with sets "multifile" directories "multi-directories;" elements multifile or multidirectory plies" plies"; (4) subroutines provided accessing modifying such way so preserve structures data; (5) use distributed computing environment which provides remote procedure calls and, one embodiments invention, transaction protocol ensure atomicity structural changes system; (6) interference concurrent operations prevented by creating "transactional" lock each system.
