Measuring real time application performance state-of-the-art

Post by Sastie » Sat, 12 Mar 2005 02:26:49


Hello,

I'm studying methods to measure the execution time of a real time
application. Does it exist a state of the art on this subject? Where can i
find it?

thank you
Seb

Kernel trace with a instrumented kernel ...


QNX 6 is offering such a feature :) -> http://www.yqcomputer.com/

Uhhh, that gives you end to end measurements. I don't think this gives
you meaningful hard number. Depends what you want to do. If you want to
go with the "Let's take end-to-end and add 20%" approach, that's fine.
However, I know a couple of big blunders recently happening with that.
If you're looking at this from a commercial point of view I would look
into http://www.yqcomputer.com/ (measurement based) or
http://www.yqcomputer.com/ (static analysis).
For both approaches there are papers floating about.

Regards,
Stefan.

No ... it gives you _all_ meaningful hard numbers of the real system!


That system is just using "the best and most accurate model of the
processor" -> but a kernel trace is using allways the real processor
in a real excuting environment.


If you want to believe in 'abstract interpretation' ... go with it :)


Was your question just a question for doing marketing ??
