To Understand M3D Thermal Plots #6

Closed yuhaohaoyu closed 2 months ago

yuhaohaoyu commented 3 months ago

In Brief:

Experiment: When running M3D, the N_tier is guarded as smaller/equal than 4. But there are 12 thermal plots under Results/result_thremal/1stacks/, each plot is titled with a 'device ID' where ID is in [0,11].
Question: How to interpret the 12 peak-heat-maps ?

Specific command:

python3 analy_model.py --thermal --chip_architect M3D --N_tile 100 --ai_model densenet121

Digging more into the code. each tier got assigned 3 sublayers. Does it reflects: upside-surface, internal, downside-surface for each tier? From 0-11, I can see the thermal reading increasing then decreasing, where the highest reading appeared around 2nd-tier-downside, 3rd-tier-upside, 3rd-tier-inside (5, 6, 7).

Does this make sense?
