 ### More Traces
 1. We are also releasing a new set of ChampSim traces from [PARSEC 2.1](https://parsec.cs.princeton.edu) and [Ligra](https://github.com/jshun/ligra). The trace drop-points are measured using [Intel Pinplay](https://software.intel.com/content/www/us/en/develop/articles/program-recordreplay-toolkit.html) and the traces are captured by the ChampSim PIN tool. The traces can be found in the following links:
