ICNT Bound #345

Open Evane5cence opened 2 weeks ago

Evane5cence commented 2 weeks ago

Hi, I found that the performance of ICNT performance is low, making my application bounded by it. May I ask how can I tune the config file to increase the ICNT performance? Thank you!

It seems that the Req_Network_conflicts_per_cycle is too high, and becomes the bottleneck. How should I solve this?

You can try different scheduling algorithms. I believe default uses iSLIP_Advance()
