 ### 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. To download these traces in bulk, please use the "Download as ZIP" option from mega.io web-interface.
