Review Comment:
Renamed `estimate_peak_bandwidth_global` to
`estimate_peak_bandwidth_global_mem`. Hopefully this makes it clear that
`estimate_peak_bandwidth_global_mem` estimates the peak bandwidth to global
memory. `estimate_peak_bandwidth` estimates the peak bandwidth depending on the
primfunc and features.
