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
