Hi Karim, Adding to what Tushar and Gabriel mentioned, you can use Garnet standalone to do this.
>From what I understand, you want to create a custom traffic pattern according to your calculations. You can create your own traffic pattern by modifying the traffic injector. You can follow the following steps in that case: 1. Add your custom traffic pattern name to src/cpu/testers/garnet_synthetic_traffic/GarnetSyntheticTraffic.hh and in initTrafficType() src/cpu/testers/garnet_synthetic_traffic/GarnetSyntheticTraffic.cc under the rest of them. 2. Add your calculation for your traffic pattern in src/cpu/testers/garnet_synthetic_traffic/GarnetSyntheticTraffic.cc. You can look at the other traffic patterns to see how you can set the input and destination of each message. 3. Use your custom traffic pattern name when you launch experiments in your command line instead of uniform-random traffic.
