[svn-r5393] Purpose:
New Feature
Description:
The VFL flush function is called immediately before a file is closed.
This can cause duplicate syncronization actions to occur, if the VFL
close function also performs them.
Solution:
Added 'closing' parameter to VFL 'flush' operation. This allows the VFL
flush function to bypass operations that will be duplicated within the VFL
close function.
Additionally, use the 'closing' parameter to bypass calls to MPI_File_sync()
when set. Since MPI_File_close() also syncronizes the file, this avoids
the terrible performance hit taken when calling MPI_File_sync() as the file
is closing.
Platforms tested:
IRIX64 6.5 (modi4)
