date: 98/03/25 10:48:21;  author: capps;  state: Exp;  
Initial revision
=============================================================================
Added support for BIFF file output. Iozone can now write Excel spreadsheet 
format. This allows one to directly access the Excel spreadsheet without 
needing to import with tab and space delimited method.

Added support for large files and threads for Solaris.

Add support for FreeBSD

Change default stride value to avoid nodalization with various spindle counts.
=============================================================================
Version 3.3:
Changed name of processor_bind to ioz_processor_bind to avoid collision
with SVR5.4.MP shared library.
Removed leading tab on an #ifdef that caused some compilers to get sick.
=============================================================================
Version 3.4:
Add support for OpenBSD
=============================================================================
Version 3.6:
Lots of code cleanup. 
Added support for OSF1 on the DEC Alpha.

=============================================================================
Version 3.17:
=============================================================================
Removed small model for Linux. In the past Iozone was forced to 
use a small model for testing Linux as the normal load caused
Redhat to panic. Redhat users have told me that the system now
works fine with the normal load. They have tested Redhat 6.1 and
it no longer panics.
=============================================================================
Version 3.18:
=============================================================================
Add support for BSDI. Base, largefiles, pthread. No async I/O

change Iozone will compile with at least 2 versions of the Cygnus
compilers.
=============================================================================
Revision 3.28        
=============================================================================
Add support for reading and writing while holding lockf() on the file.
This turns out to be important aspect of NFS benchmarking.
=============================================================================
Revision 3.29        
=============================================================================
Change calls to lockf() to calls to fcntl(). This is more portable.
=============================================================================
