I’m not sure I understand the last issue. Are you still seeing a slowdown on the 3080 compared to the 2080?


yes, it’s still slower on the 3080.



 ptrblck:

If so, could you post a code snippet, which you’ve used to profile the workload (and which we could execute to reproduce it using random inputs)?


Sorry, the project replies on complex environment, It’s not easy to post online.

Do you think the method from your last post is causing a high GPU utilization?


Yes. At first I thought it was an iteration problem, but I found that the most time-consuming step was to update the parameters (Line 112- Line 122 3).
