Hi everyone, As the issue of having a better stats format popped up, I merely wanted to grab the opportunity and highlight that there are already patches to turn the stats into Python data structures, and dump them either as shelves, or in a SQLite database (see e.g. http://reviews.gem5.org/r/1638/ and the related patches). The only issue is that the performance impact is not negligible, and the bottleneck seems to be in the C++/Python swig wrapping. More work is thus needed to improve the performance, but the functionality is there if needed.
Any volunteers? Andreas On 16/04/2014 13:39, "Lluís Vilanova" <[email protected]> wrote: >Good to know.
