komihash 4.5 #244

Closed avaneev closed 1 year ago

avaneev commented 2 years ago

Please update the speeds for komihash hash function. This version slightly improves performance on Intel processors. The output of the function is same as in v4.3.

branch komihash-4.4

avaneev commented 1 year ago

Since you have not released an update yet, you may now check version 4.5 out.

Still have to find time at home for the proper benchmark updates. Too many table tennis tournaments right now. Thanks.

Done, and I just updated the ryzen numbers so far, rest follows later (with wyhash)

avaneev commented 1 year ago

Thanks! The improvement seems noticeable.

However, there seems to be some mixup between ryzen3 and Intel i5-2300 2.8GHz measurements. The bulk speed and ticks per hash are now measured on Ryzen3, while they were measured on Intel previously (in the main table).

Yes

@rurban hi! i suggest you to reevaluate speed of komihash - I've posted an update which did not change anything except putting the "epologue" part into a separate inline function, may make a difference (usually beneficial). Also streamed hashing was implemented, it's even faster on large blocks than the oneshot function.
