Figure 1. ASCII Table

The fields are defined in the following list:

DPU Id
Name of the DPU instance .
Bat
Batch size of the DPU instance.
SubGraph
Name of subgraph in the xmodel.
WL(Workload)
Computation workload (MAC indicates two operations), unit is GOP
RT(Run time)
The execution time in milliseconds, unit is ms.
Perf
The DPU performance in unit of GOP per second, unit is GOP/s.
LdFM (Load Size of Feature Map)
External memory load size of feature map, unit is MB.
LdWB (Load Size of Weight and Bias)
External memory load size of bias and weight, unit is MB.
StFM (Store Size of Feature Map)
External memory store size of feature map, unit is MB.
AvgBw(Average bandwidth)
Average DDR memory access bandwidth.

AvgBw = (total load size of the subgraph (including feature map and weight/bias, from DDR/HBM to DPU bank mem) + total store size of the subgraph (from DPU bank mem to DDR/HBM)) / subgraph runtime
