Demetri, As I said in my previous answer, the way the rest of us do what you want to do is through .prof scripts interpreted by filebench.pl. Each entry in the profile script causes go_filebench to be run, modified with any changes specified. For example:

DEFAULTS { runtime = 120; dir = /filebench/local; stats =/tmp; filesystem = ufs; description = "randomwrite ufs"; } CONFIG randwrite8k { function = generic; personality = randomwriter; filesize = 128m; nthreads = 1; iosize = 8k; } CONFIG randwrite16k { function = generic; personality = randomwriter; filesize = 128m; nthreads = 1; iosize = 16k; } CONFIG randwrite64k { function = generic; personality = randomwriter; filesize = 128m; nthreads = 1; iosize = 64k; } CONFIG randwrite8k10t { function = generic; personality = randomwriter; filesize = 128m; nthreads = 10; iosize = 8k; } CONFIG randwrite16k10t { function = generic; personality = randomwriter; filesize = 128m; nthreads = 10; iosize = 16k; } CONFIG randwrite64k10t { function = generic; personality = randomwriter; filesize = 128m; nthreads = 10; iosize = 64k; } Separately, randomwriter.f would have your code, slightly modified as follows: # # CDDL HEADER START # # The contents of this file are subject to the terms of the # Common Development and Distribution License (the "License"). # You may not use this file except in compliance with the License. # # You can obtain a copy of the license at usr/src/OPENSOLARIS.LICENSE # or http://www.opensolaris.org/os/licensing. # See the License for the specific language governing permissions # and limitations under the License. # # When distributing Covered Code, include this CDDL HEADER in each # file and include the License file at usr/src/OPENSOLARIS.LICENSE. # If applicable, add the following below this CDDL HEADER, with the # fields enclosed by brackets "[]" replaced with your own identifying # information: Portions Copyright [yyyy] [name of copyright owner] # # CDDL HEADER END # # # Copyright 2008 Sun Microsystems, Inc.

An added advantage is that you start out with a new instance of go_filebench each time, and the six sets of results are compiled into a convenient html document for viewing.
