When the –txt 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
- Name of the DPU.
- Batch
- Batch size of the DPU.
- SubGraph
- Name of subgraph in the xmodel.
- Workload
- Computation workload (MAC indicates two operations, only available for conv subgraphs now).
- Run Time (ms)
- The execution time in milliseconds.
- Perf(GOP/s)
- The DPU performance in unit of GOP per second.
- Mem (MB)
- Total load/store size of this subgraph.
- MB/s
- Average DDR memory access bandwidth.
MB/s = (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
