Yup, you'll see 100% utilization on a kernel over a time period if it's considered active, which includes just having a single thread executing [1]. SM occupanc

Yup, you'll see 100% utilization on a kernel over a time period if it's considered active, which includes just having a single thread executing [1]. SM occupancy is great but can be a little difficult to interpret since you're not simply trying to maximize it, unlike SM efficiency.
