NAME

       cpuburn,  burnBX, burnK6, burnK7, burnMMX, burnP5, burnP6 - a collection of programs to put heavy load on
       CPU

SYNOPSIS

       burnBX
       burnK6
       burnK7
       burnMMX
       burnP5
       burnP6

DESCRIPTION

       These programs are designed to load x86 CPUs as heavily as possible for the purposes  of  system  testing
       ("burn  in").   They have been optimized for different processors.  FPU and ALU instructions are coded in
       an assembler endless loop.  They do not test every instruction.  The  goal  has  been  to  maximize  heat
       production  from  the  CPU,  putting  stress  on  the CPU itself, cooling system, motherboard (especially
       voltage regulators) and power supply (likely cause of burnBX/burnMMX errors).  The  programs  produce  no
       output, but signal hardware errors by a return code or (more likely) your machine locking up.

       burnP5    is optimized for Intel Pentium with or without MMX CPUs
       burnP6    is optimized for Intel PentiumPro, Pentium II & III CPUs
       burnK6    is optimized for AMD K6 CPUs
       burnK7    is optimized for AMD Athlon/Duron CPUs
       burnMMX   tests cache/memory interfaces on all CPUs with MMX
       burnBX    is an alternate cache/memory test for Intel CPUs

USAGE

       Burn  testing  is  designed  to  make your computer glitch if it has hardware problems, so make sure that
       nothing critical is running and all critical data is saved back to the hard-drives.  The best is  to  run
       it with filesystems mounted read-only.  Note that root privileges are not required.

       Run  the  desired  program  in the background, checking the error result.  You'll may want to repeat this
       command for every processor you have in an SMP or HyperThreading system.  For example,

           burnP6 || echo $? &

       Monitor progress of cpuburn by ps.  You can monitor CPU temperature and/or system voltages  through  ACPI
       or  using  the  lm-sensors package if you system supports it.  When finished, kill the burn* process(es).
       For example,

           killall burnP6
