Houdini 3 update does behave the same in 64-bit and 32-bit.

[ernest]

See my previous post
http://www.talkchess.com/forum/viewtopi ... 075#489075

Just received the Houdini 3 update and tested it in 64 and 32-bit.
On my Core 2 Duo (no POPCNT ) the installed 64 and 32-bit exe(s) now both behave the same, but both different from the original version. Speed (kN/s) seem unchanged from the original version.

It would be interesting to see the infinite analysis result (start_position, 512 MB hash, 1 thread) by somebody who uses POPCNT (i7, i5, ... modern processors) and according to Robert H "does not need" to update his Houdini 3.

Herebelow my result:

Ernest
what was the original problem?
I know it was related to popcnt, but what did the user see wrong?
thanks

Ernest, I find exactly the same analysis as you, for example at depth 21:

I suppose this is with the original H3, not the update.

[Vinvin]

The analyse was not the same with and without popcount (SSE).
Robert found the little bug in the non-SSE code.

[Houdini]

Ernest, I find exactly the same analysis as you, for example at depth 21:

I suppose this is with the original H3, not the update.

For a Core i5 there is no difference.

Hi Kim,

The test should be with your original H3 (from around october 20) and 512 MB hash

Edit: I see your test was made with 1024 MB hash
Obviously, you don't need the update...

Hi Kim,

The test should be with your original H3 (from around october 20) and 512 MB hash

what does this mean?
I only have one copy.
Of course this is not the update, it was said with popcnt it was not needed.
what made you think this was not the original?

[ernest]

what made you think this was not the original?

Nono!!!... by original I meant "not the update"!!! All clear!...

Actually, only people with "old" machines (like me) need the update, for 32-bit and 64-bit.
