ubench(8) Linux System Manager's Manual ubench(8)NAMEubench - Unix Benchmark Utility
SYNOPSISubench [-cmhs]
DESCRIPTIONubench 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 calcu‐
lations to integer is about 1:3. Ubench will spawn about 2 concurrent
processes for each CPU available on the system. This ensures all avail‐
able 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 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.
