[Yt-dev] yt timing function

[Matthew Turk]

Hi Stephen,

I've written up some code and stuck it in the yt branch of the hg
repo.  The changeset is here:

http://hg.enzotools.org/yt/rev/87dcd3182260

So far it's kind of rudimentary, but it exposes two functions for
decorating.  The slightly more sophisticated example you have proposed
would be better handled through an extension to the logging module,
which would require adding a new filter and a new loglevel to the
yt/logger.py module.  You could then have it transparently call the
yt_counters object as necessary.

Here's a script to demonstrate the simple stuff I put in:

It would also be nice to hook into atexit to have it print these on exit:

The nice thing about using mylog is Matt has already got processor labels working, and it has timestamps. It would be therefore also trivial to have nested benchmarked sections, etc...
