Re: Houdini 6 has been released

option name Threads type spin min 1 max 80 default 1 (and yes..max 80)!! Correct, the very early Standard purchasers have received a version that was inadvertently too highly threaded. This has already been corrected in the current download packages. So you will lose this unexpected advantage with ...

Re: Houdini 6 has been released

Will there be minor patches leading up to TCEC Robert ? :lol: You surely haven`t shown all you cards yet, have you ? There are minor patches between TCEC rounds, not leading up to it. And why would he tell you if he had shown all his cards? First of all I didnt expect Houdart to tell me or anyone e...

Re: Nodes/sec. with last new CPU's!

Maybe I can run a final match between (20 threads at 40+0.4) and (20 threads at 80+0.8) so that we also know the Elo improvement from doubling the time. Results from this match are now in. 800 games yield (+195 -58 =547) or 60±13 Elo in favor of the (80+0.8) engine. The previous matches estimated t...

Re: Houdini 6 Caused Exception Error

From the additional reports we received it appears that the issue is strictly related to the "Houdini 6 Pro" compile. There are no problems with the "Houdini 6 Standard" engine. We're trying to understand the origin of the problem, and intend to release a fix ASAP. Until the fix appears, if you're e...

Re: Houdini 6 has been released

I have a ryzen 1800 cpu and "x64-popc" is apparently the version of H6 that is installed. Correct. AMD Ryzen officially supports BMI2 instructions, but their implementation is very slow (the instructions are emulated, if I understand correctly). On Ryzen the BMI2 or "pext" compiles are about 20% sl...

Re: How many kn/sec makes Houdini 6 on a Ryzen7 CPU?

For your info, Houdini also accepts a shorter "set" command:

Code: Select all

set threads x
set hash xxxx
go movetime 60000
This works for all options that don't have spaces in their name.
Saves some typing!

Re: Houdini 6 Pro and large pages

Correct, there is no need to turn off NUMA if you're running on a system with only a single NUMA node. The NUMA support will only make a difference if Houdini detects at least 2 NUMA nodes (as reported by the appropriate Windows function). How much stronger is Houdini with Numa and LP ? It highly d...

Re: Houdini 6 Caused Exception Error

Tried, but while i can easily replicate the issue, it doesn't generate a logfile. (Using Fritz 14 GUI on playchess engine room) Seems that the issue is happening at the end of the opening book. I can however analyse for hours without any problem I suggest that we handle this problem via e-mail, I'v...
