[svn-r5799] Purpose:
New feature.
Description:
Added MPI-posix VFL driver. This driver uses MPI to coordinate actions, but
performs I/O directly with posix sec(2) I/O functions. This driver should
_NOT_ be used if the file accessed is not on a parallel filesystem.
Platforms tested:
FreeBSD 4.6 (sleipnir) w/parallel & IRIX64 6.5 (modi4) w/parallel
