Hi Ali,
Sorry for the delayed response to this. I took a
look at the ISCA-33 slides and am basing my comments
mostly on those.
Basically, I think what you present should depend on
the audience, and you are in the best position to
know this. If the audience is mostly people who are
currently using M5 (i.e. people on this list), then,
I think you can do several things:
* Condense the intro/overview section to ~5-10
slides (from 18 currently) -- there's a lot of stuff
here that we'd already know or is relatively easy to
figure out.
* Completely omit the "Compiling / Running M5"
section (12 slides) -- or, at least, condense it
down to ~1 slide and have the details as backup for
later reference. If we're already using M5, we know
how to do this.
* Re-organize the "Current M5 Object Models" section
to trace a detailed example of a modification that
would affect all three areas (I/O, Memory, CPU) --
adding some sort of new networking interface /
protocol, perhaps? -- which would also eliminate the
need for the "Extending M5" section (since it's
integral to the previous section).
* Add a "Putting It All Together" section that ties
together the whole thing -- as Philip suggested, you
may not actually need to spend a lot of time on
this.
I would think that should give you plenty of time to
actually work through an example.
If the audience is mostly people who *aren't*
currently using M5, then you may want to spend more
time on overview (as you said, I would describe most
of the ISCA-33 tutorial as overview) -- but again,
you're in the best position to know this.
I hope this helps!

Time is why I suggested building up the complete
example through
examples for each concept as you cover the rest of
the content. The
"putting it all together" section could be covered
fast in the
tutorial but would be a nice summary to go back
and read.

Ali, would it be possible to discuss
heterogeneous multicore
configurations (perhaps with examples) in the
section where you plan to
discuss configurations?

Thanks for the comments Vilias and Philip.
I have a few more questions. Looking at the
previous tutorial slides, it
doesn't seem like there is much history (just
a couple of slides), am I
missing something? By overview I'm assuming
that you mean the majority of the
presentation (and not just the first section
titled as such). Without the
overview slides about various objects do you
think a section on, "adding
feature X to component Y," would make sense? I
think it's a good idea to do
something like that, I'm just trying to figure
out what can be cut to make
room (since we're limited to about the same
amount of time).
Thanks,
Ali

I'm not sure what 'typical' usage of M5 looks
like, but I for one spend a
lot of time understanding the existing code
(both C++ and Python) in order
to modify / extend it -- as opposed to either
using it as is or writing
entirely new code. I think more emphasis in
a tutorial on how to use M5 in
that capacity (and less on history /
overview) would be helpful.
I personally wasn't familiar with Python, so
I had to spend a lot of time
understanding (relatively simple) Python code
-- for example, the code
provided in se.py or fs.py -- in order to
change it to suit my needs. It
would be great if you could cover the basics
of the Python infrastructure
-- and perhaps use one of those files as part
of the example (since they
are likely the most commonly used Python
files, from a user perspective).
Echoing Philip's suggestion, perhaps the
'complete example' he suggests
could be a 'How to' for a (simple)
modification to the existing code? You
wouldn't need to actually dwell on the
details of the new feature, but it
would allow you to highlight a variety of
areas in the simulator in the
process.

I took a quick look at the ISCA 2006 tutorial
and it reads well as an
overview of a manual but a complete example
including a good fraction
(obvious not all) of the features at the end
would be a useful
addition to put it all together.
A possible approach: use pieces of this
complete example to introduce
the features, then go over the whole thing at
the end.

Everyone,
Below is roughly the outline we've used for
previous M5 tutorials.
We're in the process of updating our slides
for the ASPLOS tutorial in
a few weeks and would like any input you
have. Irrespective of if you
plan to attend the tutorial or not we would
like input about what
should be covered in more detail and what
we're spending too much time
on.
Thanks,
Ali
