Rule Description
WRN HighPipeUtilization ALU is the highest-utilized pipeline (61.3%) based on active cycles, taking into account the rates of its different instructions. It executes integer and logic operations. The pipeline is well-utilized, but might become a bottleneck if more work is added. Based on the number of executed instructions, the highest utilized pipeline (61.3%) is ALU. It executes integer and logic operations. Comparing the two, the overall pipeline utilization appears to be caused by frequent, low-latency instructions. See the Kernel Profiling Guide (https://docs.nvidia.com/nsight-compute/ProfilingGuide/index.html#metrics-decoder) or hover over the pipeline name to understand the workloads handled by each pipeline. The Instruction Statistics section shows the mix of executed instructions in this kernel.
INF Occupancy This kernel's theoretical occupancy is not impacted by any block limit.
