NAME
     ubench - Unix Benchmark Utility

SYNOPSIS
     ubench [-cmhs]

DESCRIPTION
     ubench  is an attempt to introduce a single measure of perfomance among ma-
     chines running various flavors of Unix.

     Ubench is executing rather senseless  mathematical  integer  and  floating-
     point calculations for 3 mins concurrently using several processes, and the
     result is Ubench CPU benchmark. The ratio of floating-point calculations to
     integer  is  about 1:3.  Ubench will spawn about 2 concurrent processes for
     each CPU available on the system. This ensures all available raw CPU horse-
     power is used.

     Ubench is executing rather senseless memory allocation and memory to memory
     copying operations for another 3 mins concurrently using several processes,
     and the result is Ubench MEM benchmark.

     Ubench will take an average of CPU and MEM benchmarks and calculate  Ubench
     AVG  benchmark  which  is supposed to represent the true computing power of
     the system.

OPTIONS
     -c     With this flag ubench will only execute CPU benchmark.

     -m     With this flag ubench will only execute MEM benchmark.

     -s     Prevents ubench from spawning multiple processes.  This  will  force
	    ubench to use only 1 CPU on the system and the result will be Ubench
	    Single CPU and Ubench Single MEM benchmarks.

     -h     Prints usage information.

FILES
     The  documentation  on  ubench  and  current  list of ubench benchmarks are
     available at
     http://www.phystech.com/download/ubench.html

BUGS
     The ratio which CPU and MEM scores contribute to the  CPU	and  MEM  bench-
     marks,  and  to the final AVG benchmark has been calculated so that CPU and
     MEM scores averaged over several  widely  different  computer  systems  are
     equal  to	each  other and make equal contribution to average AVG score. As
     more and more benchmarks are available, the ratio will be	calculated  more
     precisely.
