Compile

ChampSim takes a JSON configuration script. Examine champsim_config.json for a fully-specified example. All options described in this file are optional and will be replaced with defaults if not specified. The configuration scrip can also be run without input, in which case an empty file is assumed.

$ ./config.sh {1core.json or 2core.json or champsim_config.json}
$ make -j9 TAG={uniqueid whatever you want to append to binary name or it could be just empty field}

Download DPC-3 trace

Professor Daniel Jimenez at Texas A&M University kindly provided traces for the 3rd Data Prefetching Championship (DPC-3). They can be found here (http://hpca23.cse.tamu.edu/champsim-traces/speccpu). A set of traces used for the 2nd Cache Replacement Championship (CRC-2) can be found from this link. (http://bit.ly/2t2nkUj)

This repo is part of research project carried out in a semester long course work of Memory Systems and Architecture.

Project is titled as "Selective bypassing of write intensive sets to improve lifetime of NVM based last level cache"

There are knobs on enabling/disabling bypassing, aggressive/selective bypassing inc/constant.h
