Thx for reporting the benchmarks. Looks good except for Reduce Max on I8, I32, 2^28. A 14% slowdown is unfortunately below @gevtushenko's rule of "no regressions of more than 2% compared to previous implementation on 2^24+ problem sizes". Could you please investigate the cause of this regression? We should try to fix this.

fbusato commented 3 days ago

14% slowdown is too large. Let me see if I can fix it

fbusato commented 3 days ago

@bernhardmgruber (and @gevtushenko) All routines that show regressions here have been "artificially" improved by the following problem. Non-standard binary operators were recognized as operators that can be optimized as binary tree reduction. In fact, the code can't optimize these operators because it has no knowledge of their structures. In summary, these regressions cannot be avoided for user-provided binary operators
