Houdini 3 does not behave the same in 64-bit and 32-bit.

Post by ernest »

In the Houdini 2 series, it could be verified that the 64-bit and 32-bit versions behaved the same, for instance through infinite analysis of a position, using 1 thread for reproducibility.
This is no longer true for Houdini 3.
Compiler issue?
Maybe Robert can comment.

Herebelow the analysed position is the start_position: KiloNodes are different starting depth 15.

My CCRL 40/40 testing results with Houdini 3 32-bit aren't as impressive as I expected so far. Early days I know, but.........

Ernest, thank you for signaling this. It's certainly not the intent that the 32-bit and 64-bit produce different results.
I will investigate and report back here.

Cheers,

Hi Robert,

Note that I have a dual-boot system (XP Home 32-bit and XP Pro x64) so I could activate the Houdinis 3 w32 in XP Home 32-bit and the Houdinis 3 x64 in XP Pro x64.
I even tried to install Houdini w32 in Fritz GUI in XP Pro x64: it "seems" to work, produces yet again a different infinite analysis, but actually it's not supposed to work :) as double clicking on Houdini_3_Standard_w32.exe in XP Pro x64 environment will give, in console mode:

Code: Select all

Houdini 3 w32
(c) 2012 Robert Houdart

info string 2 processor(s) found
info string 128 MB Hash
info string No valid license found
Which leads to the (not too important question): will it be possible, some day, to activate Houdini 3 w32 in XP Pro x64 environment ?

How can you install Houdini 3 w32 in XP Pro x64 environment? We only get x64 engine when installing in x64 system.

If you copy the binary installed in your XP Home 32-bit, it can't work at all.

that's a good sign (that he may have found a big bug which will leave H3 much greater after it is solved).
