Removed workload items till they # have been modernized. Added database server test. # 11/14/89 - Made modifications to reflect new version of fstime # and elimination of mem tests. # 10/22/90 - Many tests have been flipped so that they run for # a specified length of time and loops are counted. # 4/3/91 - Cleaned up and debugged several test parameters - Ben # 4/9/91 - Added structure for creating index and determing flavor of UNIX # 4/26/91 - Made changes and corrections suggested by Tin Le of Sony # 5/15/91 - Removed db from distribution # 4/4/92 Jon Tombs fixed for GNU time to look like # BSD (don't know the format of sysV!) # 12/95 - Massive changes for portability, speed, and more meaningful index # DCN David C Niemi # 1997.06.20 DCN Fixed overflow condition in fstime.c on fast machines # 1997.08.24 DCN Modified "system", replaced double with # whetstone-double in "index" # 1997.09.10 DCN Added perlbench as an Exhibition benchmark # 1997.09.23 DCN Added rgooch's select as an Exhibition benchmark # 1999.07.28 DCN "select" not compiled or run by default, because it # does not compile on many platforms. PerlBench also # not run by default. # 2007.09.26 IS Huge rewrite -- see release notes in README. # 2007.10.12 IS Added graphics tests, categories feature. # 2007.10.14 IS Set and report LANG. Added "grep" and "sysexec". # 2007.12.22 IS Tiny fixes; see README. # 2011.01.13 KDL Fix for parallel compilation. ############################################################################ # CONFIGURATION ############################################################################ # Version number of the script. my $version = "5.1.3"; # The setting of LANG makes a huge difference to some of the scores, # particularly depending on whether UTF-8 is used.
