NAME

ubench - Unix Benchmark Utility

SYNOPSIS

ubench [-cmhs]

DESCRIPTION

ubench is an attempt to introduce a single measure of perfomance among machines 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 horsepower 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.

BUGS

The ratio which CPU and MEM scores contribute to the CPU and MEM benchmarks, 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.
