There was a problem hiding this comment.
A reference value for PT is changed to stay aligned with OV. Interestingly, the new value for OV (0.80873) is also the value that PT backend gets on some devices.

Changes
Compute division inside SE algorithm always as
a/binstead ofa*(1/b)in some cases.Reason for changes
During implementation #2727 some choices were made regarding how division operation is computed in order for the changes to be completely aligned with the previous implementation. Namely, before #2727 some divisions were computed as
a*(1/b), and this is currently still the case.The way these divisions are computed originally was not intended. Now, all divisions are aligned to the
a/bform.Compression time and memory are roughly the same.
*time column includes PT -> OV conversion time.
