To:	linux-kernel@vger.rutgers.edu

Hi all,

I've recently uploaded version 1.2.1 of VA-CTCS, VA's test suite for
stressing hardware, to the locations mentioned at the bottom of this
e-mail.  Please read README.FIRST if you are not familiar with this
software -- this system loader has been known to damage marginal hardware,
including catching system power supplies *ON FIRE*, and neither VA Linux
Systems nor myself will be responsible for any damage caused.

What's new in this version since 1.1.7?  Here is a summary:
- Lazy Developer Installation method:
	tar -zvxf ctcs-1.2.1.tar.gz
	cd ctcs-1.2.1
	-- and CTCS takes care of compiling itself and checking your system
	for required binaries, etc.
- Many new modules:
	Included in VA-CTCS is Robert Redelmeier's CPU/Memory stress
	testers, the BYTE benchmarking suite, crashme, as well as some
	new VA authored modules (such as the Fast kernel-compile test)
- New command line options to "newburn" with -h to get help.
- Enhanced memory tester checks for error consistency and provides context
  for memory failures.
- More compatibility with non-Red Hat distributions and the 2.4 kernel
- Some work started to make CTCS more friendly to non-x86 platforms, but
there are still issues.

What is VA-CTCS?

VA-CTCS consists of a test iterator, a collection of test modules, and a
test generator.  The main test program, "newburn", detects your hardware
and comes up with a custom combination of tests designed to beat on your
system and its peripherals, modified by your parameters.  VA
Linux Systems has released VA-CTCS under the GPL.

Why is VA-CTCS useful for kernel developers?

CTCS is useful for:
	- Use as a generic system loader
	- Iterating your own test code and recording failure data for you
	  while you concentrate on debugging
	- Bashing at the filesystem/buffer cache layer with the data and
	  block test modules
	- and much more..

If you've ever spent a lot of time scripting tests to report time to
failure, number of iterations, record all of it to a synchronous logfile,
etc, you'll find CTCS to be handy.  Besides, as you know, when a system is
thrashing lots of obscure problems can come out of the woodwork..
