thanks ali!
I realized that I just have to read the cpu2000.py in order to get
things up and running(but that would'nt be possible w/o your
explanation). Additional questions though,
1. does it really take a long time for a benchmark ( i.e. gzip) to
run? It's been running for 1 hr now.
The time depends on what input set you're using. The reference input
would probably take many hours to run to completion. The smred input
set can complete a couple of hours.
2. what is the purpose of specifying the output file
(input.source.out) in M5? if it's okay can you please point me to a
URL detailing the rudimentaries of running benchmarks? the spec2000
documentation is a little bit biased on explaining things when
running Spec2000 in an operating system(i'm not surprised).
http://www.m5sim.org/wiki/index.php/Running_M5
http://www.m5sim.org/wiki/index.php/Simulation_Scripts_Explained
Those URLs are all we have on m5sim.org at the moment, perhaps
they'll be of some use. If you feel motivated, feel free to create a
new page that documents the problems and solutions you've been having.
3.in the gzip_source class in cpu2000.py, what's the difference
between {ref,smred,mdred,lgred} when you just assigned self.args
with the same value in all 4 choices?
They are various input sets ref is the reference from spec, the
others are of various sizes I think all from the minniespec set. The
selection of the different directories in cpu2000.py selects the
different sets since they all have the same input file names.
4. what are the differences between the 'ref','test','train'
directories in the input directory of each benchmark?(how will i
know which one to use)
The ref/test/train directories are different input sets. Generally
that distinction is only useful to compiler people who for example
want to profile the code with one set of inputs and then run it with
another set.
