I've put a new release of sys_basher on the web.

http://www.polybus.com/sys_basher_web/

sys_basher is a multithreaded system stress test. It runs on any Linux
system. It can also run on Windows under Cygwin although the Cygwin
version has slightly reduced functionality.

This version adds report files which gives detailed memory and disk
bandwidth numbers as well as 16,32, and 64 bit integer performance and
single and double precision floating point performance.

On my Linux system with 2 PIII's and less than a gig of memory (896M
installed but some robbed by video card so 904,352K is visible) it prints
this at start up:
Shared RAM: -4616046987694877.000000 KBytes
You should define the --help option as its kind of a defacto standard.
In this sample output:

What do the 2 MB/S figures represent? min and max throughput?
I also wasnt sure how to decode the display of the following data:
