Latest commit aa604c1 Sep 26, 2013 @roblatham00 roblatham00 committed with morrone Teach IOR about GPFS hints (gpfs_fcntl)
GPFS supports a "gpfs_fcntl" method for hinting various things,
including "i'm about to write this block of data".  Let's see if, for
the cost of a few system calls, we can wrangle the GPFS locking system
into allowing concurrent access with less overhead. (new IOR parameter

Also, drop all locks on a file immediately after open/creation in the
shared file case, since we know all processes will touch unique regions
of the file.  It may or may not be a good idea to release all file locks
after opening.  Processes will then have to re-acquire locks already
held.   (new IOR parameter gpfsReleaseToken)

0. If "configure" is missing from the top level directory, you
   probably retrieved this code directly from the repository.
   Run "./bootstrap".

   If your versions of the autotools are not new enough to run
   this script, download and official tarball in which the
   configure script is already provided.

1. Run "./configure"

   See "./configure --help" for configuration options.

2. Run "make"

3. Optionally, run "make install".  The installation prefix
   can be changed as an option to the "configure" script.
