摘要: This paper presents the design of a MPI (Message Passing
Interface) - basedparallel file system,MPFS. MPI-IO is an
extension of MPI to support flexible logical file partition and
physical file organization, as well as a rich set of file access
functions. MPFS enables users to specify both logical file
partition among userprocesses and physical file data layout
across data servers. Present implementation includes full
support of file data distribution, asynchronous I/O, shared file
pointers,collective I/O operations, and limited support of data
layout hints. Moreover, MPFSachieves portability by developing a
user library that conforms a generic UNIX interface. However,
MPFS does not support FORTRAN interface, error handling
andprofiling in MPI-IO specification. MPFS has been implemented
on a workstationcluster connected by Fast Ethernet. The
performance measurements of MPFS showthat the message passing
overhead is minimal but the performance is limited by the
bandwidth of Fast Ethernet.
