I’m trying to understand the description of available metrics in NCU.
But I couldn’t understand what non-metric names or not directly evaluable mean in the example below.
(Kernel Profiling Guide :: Nsight Compute Documentation )
## non-metric names -- *not* directly evaluable sm__inst_executed # counter smsp__average_warp_latency # ratio sm__throughput # throughput
Could you clarify what evaluable means and why it is not evaluable?
I’m especially interested in
smsp__average_warp_latency and related metrics since I want to know warp stall reasons and how much significant it is.
Plus, I wonder why the average latency is represented as a ratio, not cycles or time.
Thanks in advance.
