This is the command that is mentioned in the previous pdf file that I have shared. I need the values for all the metrics for the BFS benchmark in Rodinia Benchmark. However, on executing this command I get the following error:
Device Quadro RTX 4000 (TU104)
==WARNING== The below metrics are either invalid or don’t have suffixes.
regex:.*
I am following the steps as outlined but still Iam getting the error. If anyone can help it will be great.
query-metrics-mode suffix does not support specifying metric base names via regex. You can simply use
ncu --query-metrics-mode all --devices 0
to achieve this. Note that specifying a target application binary when querying metrics is not possible/useful. You should first determine the metrics to collect and then collect them for the specific application. I recommend to not collect all possible metrics, though, but rather the “full” set and/or a subset of all possible metrics that is required for your analysis. You can combine --set full with --metrics.
ncu --set full ./bfs
ncu --metrics <comma-separated list> ./bfs
I am trying to collect all metrics when profiling. However, I was hoping to get something like --metrics “regex:.*” to work and avoid typing all metrics. Unfortunately, I could not get that to work.
Currently I am using
nv-nsight-cu-cli \
--target-processes all \
--set full \
--kernel-id ::my_kernel:32 \
-fo quick-test \
quick-test.py
However, it is not collecting some of the memory analysis metric as it can be seen below
