....I O calls can be synchronous or asynchronous, allowing computation to overlap with I O. ViC I O provides a consistent interface on several operating systems, using several file systems. ViC files can exist in the Unix file system, in the Galley parallel file system [NK96, Nie96] or as MPI IO [MPI96] files. Interprocessor communication in the ViC library uses MPI [SOHL 96] 31 2.5 Summary ViC extends and re implements the C data parallel language to support out ofcore programming. The ViC compiler, vcc, translates C source into C code which calls the ViC runtime system to ....

....to access non contiguous regions of a le. Thus, we want the I O description capability provided by PVFS2 to be as expressive as possible. The idea is to encapsulate as many access patterns as possible using the I O description. This would allow it to support parallel I O interfaces such as MPI IO[5] and SIO[9] that require the underlying system to support non contiguous accesses in a convenient manner. The older PVFS1 requests were limited as to what they could express. In PVFS1, the default distribution is striped. A le striped on N I O nodes has N les, one on each I O node, containing ....
