gem5McPATparse v0.1

An attempt to adapt gem5 output to McPAT input. This version is implemented in Bison, Flex and C/C++. It also uses the library RapidXML for C++. Based on Fernando Endo's notes [1], this parser extracts the parameters and statistics from the output of gem5, 'config.ini' and 'stats.txt', and fills the equivalent fields in a XML based on 'template.xml'.

Compilation

To compile this version:

make

Running the parser

To run the parser and generate 'output.xml':

make run

It is also possible to run as (all these options are mandatory):

./gem5McPATparse -x <template_file> -c <config_file> -s <stats_file> -o <output_file>
./gem5McPATparse --xmltempalte <template_file> --config <config_file> --stats <stats_file> --output <output_file>

In order to get help from the program:

./gem5McPATparse -h

Software needed

It has been tested in a Linux distribution with gcc version 5.2.1, bison version 3.0.2, flex 2.5.39 and make 4.0

The template has been adapted for the last version of [McPAT 1.0]. The gem5 version tested is from 03/2015, but it should work for a more recent version.

TODO list

What can be done or improved:

Parse system.mc params and statistics
Check why dcache block_size must be 32 in order to work
Code clarity
Portability [?]

Bugs

This tool is currently in development, so if you find a bug, you can open an issue. If you do not agree with the translation of a parameter or value, please do the same in order to discuss it!

Limitations

This first version is focused on the compatibility of the output of memory system and core in gem5 with the input of McPAT. Thus, other components such as PCIe will be ignored by the moment.

Most of translations only work for X86 Architectures. It is needed to find the synonyms for the rest of ISAs
