Profiling Information¶
Overview¶
The quadric SDK’s output contains profiling information. Namely, it contains a breakdown of execution cycles by type, which looks like something like this, created by executing this network in the SDK:
TotalCycles: 18,387,722
predication : ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 1,981,324
compute : ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 3,616,340
