When the --txt or --txt_summary option is used, vaitrace prints an ASCII table, as shown in the following figure:

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). The unit is GOP.
RT (Runtime)
The execution time in milliseconds, unit is ms.
Perf
The DPU performance in unit of GOP per second. The unit is GOP/s.
LdFM (Load Size of Feature Map)
The external memory load size of the feature map. The unit is MB.
LdWB (Load Size of Weight and Bias)
The external memory load size of bias and weight. The unit is MB.
StFM (Store Size of Feature Map)
The external memory store size of the feature map. The 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
