Hi Mahmood, A slight correction there, there is a patch going out soon that will enable the stats to be dumped in a Python data structure rather than as a text file (replacing stats.txt). This avoids having to parse a text file and match that to the system description. The json format is used to describe the system configuration and is already part of gem5 (replacing config.ini).
I am afraid I do not have a date for the Python stats patch…but it should be in the order of weeks.

Any news for that?

I'd like to use that script to automatically get power numbers. So I was wondering if you could share your exprience or your updated script so lazy engineers like me save some time.

I've had much more success with #2, but for various reasons, I can't make my updated version available yet. It probably wouldn't do what you need it to anyway. #2 might look a bit complex, but all it does is take a template McPAT XML file (mcpat-template.xml) and plug in values from gem5's config.ini and stats.txt. Most of the values in mcpat-template.xml are hardwired, but some are of the form value="{...}". The script just replaces everything inside {} with values from gem5. If I remember correctly, the problems with tool #2 are that the format of stats.txt has changed slightly, there are some values in the template that shouldn't be hardwired but are, and in some cases the template is picking up the wrong value from gem5. To get #2 to work, the first thing you'd need to do is get m5-mcpat.pl<http://m5-mcpat.pl> to correctly fill in the template. Depending on how comfortable you are with Perl, you might be better off rolling your own script in something like Python to complete the template--m5-mcpat.pl<http://template--m5-mcpat.pl> has some particularly nasty Perl in it. Then it's just case of figuring out what the values in mcpat-template.xml correspond to in config.ini and stats.txt. Here you can focus on the parameters you're actually researching. For the CPU core, this isn't too difficult; if you're working on something like cache or NoC, it could be hard. Keep in mind that McPAT isn't nearly as configurable as gem5, so a lot of the things you can do in gem5 won't readily translate over to McPAT. Hope this helps. -Erik On 05/10/12 04:26, Ding, Hongyuan wrote: Dear All, I'm new to gem5. Recently I tired to integrate McPAT on gem5.

Does anyone has a modified tools for McPAT integration or some clues on how to fix it?
