System Environment Commands

In this appendix we list some commands that report information that may be relevant for your experiment. We use here the syntax for the --comment option of labrun. If you have other commands you believe others may find useful, please let us know so we can add them to this list.

Cache Information

IRIX:

Instruction cache=`hinv`:Instruction.cache.size[\s:]+(.*)
L1 data cache=`hinv`:Data.cache.size[\s:]+(.*)

Solaris:

Instruction cache=0x`prtconf -pv`:icache-size Bytes
L1 data cache=0x`prtconf -pv`:dcache-size Bytes

The information from prtconf is in hex. The 0x before the command indicates that labrun should convert the number of bytes reported to decimal.

CGAL version

CGAL version=@$CGALROOT/include/CGAL/config.h:CGAL_VERSION\s+(.*)

Compiler version

Compiler version=`$CC -v`: version

Graphics card (IRIX)

Graphics card=`hinv`:Graphics\sboard

LEDA version

not using CGAL

LEDA version=@$LEDAROOT/CHANGES:__LEDA__

using CGAL

LEDA version=`cgal_leda_version`

Because CGAL may have been installed with a different version of LEDA than the one pointed to by LEDAROOT, the script cgal_leda_version is used to find the correct version number. The script is as follows:

#! /bin/sh -f

cat $CGAL_MAKEFILE |grep "/LEDA.*/incl"|sed -e s:incl:CHANGES: > /tmp/name
if [ -s /tmp/name ] ; then
  file=`cat /tmp/name`
  cat $file|grep "#define __LEDA__"|head -n 1|sed 's:#define __LEDA__::'
  rm /tmp/name
else
  echo "None"
fi

Notice that this script assumes the environment variable CGAL_MAKEFILE has been set. If this makefile does not correspond to one created with LEDA support, the value "None" is returned.

Qt version

Qt version=@$QTDIR/README:version\s+(\d+(\.\d+)*)

We also show here the commands used to extract the information automatically recorded in the log file in case these commands somehow correspond to different information on your system.

OS

OS=`uname -s`

Hardware

Hardware=`uname -m`

Machine

Machine=`uname -n`

Processor

IRIX:

Processor=`hinv | grep '.* MHZ .* Processor' |
awk '{printf \"%d MHz %s\", $2,$4}'`

This command should be on a single line.

Linux:

Processor=@/proc/cpuinfo:cpu.MHz[:\s]+(\w)+ MHz
@/proc/cpuinfo:model.name[\s:]+(.*)

This command should be on a single line.

Solaris:

Processor=`psrinfo -v | sed -n -e '1,4 s/.*The \(.*\)
processor operates at \(.*\),/\2 \1/p'`

This command should be on a single line.

Memory size

IRIX:

Memory size=`hinv`:Main.memory.size[\s:]+(.*)

Linux:

Memory size=@/proc/meminfo:MemTotal[\s:]+(.*)

Solaris:

Memory size=`prtconf -pv`:Memory.size[\s:]+(.*)

L2 data cache

IRIX:

L2 data cache=`hinv`:Secondary.*cache.size[\s:]+(.*)

Linux:

L2 data cache=@/proc/cpuinfo:cache.size[\s:]+(.*)

Solaris:

L2 data cache=0x`prtconf -pv`:ecache-size Bytes
