We can just decrease the default values in the axis.

I would prefer to omit this skipping condition. I recognize that we can't have 1M distinct elements in 1K rows, but this condition adds a lot of friction when sweeping NumRows for the high cardinality case. It forces me to run a full factorial of matching NumRows and Cardinality values and filter the outputs for the highest Cardinality unskipped for each NumRows.

I'll rewrite this logic. Thanks for the feedback!

Hmm. @GregoryKimball I reviewed the NVBench docs and I don't see a way to filter out certain jobs except by skipping them. https://github.com/NVIDIA/nvbench/blob/main/docs/benchmarks.md#beware-combinatorial-explosion-is-lurking
We might be able to use a string axis like {"100,100", "100,1000", ..., "1000000000,1000000000"} and parse it, but that's hard to maintain.

NVIDIA/nvbench#80 can solve this issue but the PR has been stalled for a while.

Thanks guys, here is a performance snapshot of these benchmarks on A100 I would like to merge this update ASAP and then have @srinivasyadav18 pull the changes into #16484 I'm noticing that these throughput numbers on A100 are about 10x lower than what @srinivasyadav18 posted for H100. This is another reason I'm interested in running wider benchmarks on #16484 |

Just fixed the CI style check. I'll merge this when CI passes. |
