Description

If we run something like

https://gridwise-webgpu.github.io/gridwise/examples/scan_sort_perf.html?primitive=sort_keys&inputLengthStart=8388608&inputLengthEnd=33554432

then the plotted sort bandwidth is pretty modest. I want to check if it is reasonable. I need to go look at how I am calculating sort data volume and probably do some lower-level benchmarking.

Research direction

Start with the scan_sort_perf.html example URL and inspect how sort data volume is calculated for the sort_keys benchmark. Compare the plotted sort bandwidth with lower-level benchmark results to determine whether the calculation or the measured performance is responsible. Done means documenting whether the bandwidth is reasonable and identifying the relevant correction or follow-up.
