Houdini in IDeA

[perejaslav]

Has Anybody tried to use it? How it works? Any bugs detected?

BTW, Robert. Could you please compile Houdini 1.5 1CPU ...

[Damir]

You can adjust the number of cores to 1 manually....

Yea I know that but anyway I used to run 1CPU engines for my IDeA Projects. Maybe this is only an odd little fancy

A 1-core as compiled engine is useful because sometimes only a single core is required. Specifically:

1) The setting and saving of parameters/personalities (including the number of threads/cores) isn't always reliable, as in ChessBase running under Wine/Ubuntu, and not only then.

2) A 1-core engine could be used in e.g. IDeA/Aquarium conveniently leaving the multi-core version as it is for IA in Sandbox/Aquarium.

In my remote systems (i7-920 64bit and AMD Opteron 856x4 32 bit) Houdini 1.5 has troubles limiting itself to one core despite my RTserver settings. Two cores usually overtake more than 25% CPU each and the other two eventually go idle. This never happened with previous Houdini versions.
My workaround has been to simply use 4 cores at once. That way the machines run at 100% all the time without troubles. This means less remote engines but they are faster.

Hello Slavik & other contributors to this thread,

I could compile a 1-CPU version, my question is whether it is really useful.
Why is it difficult for the Aquarium IDeA to remember a simple "Threads=1" UCI option for Houdini?
Are there any users that successfully use Houdini in the Aquarium IDeA?

Nothing is simple in Aquarium.

I'm using the dual processing houidi version in aquiarium and idea . works just fine.

Robert,

IDeA in your local machine works flawlessly assigning one core to each instance of Houdini 1.5
It's the remote versions of Houdini where I have found troubles, i.e. using the remote RTServers to communicate the remote engines with your local Aquarium.

The point is that an engine can be used for different things, requiring different settings (even within a single GUI such as Aquarium), and the setting and saving of parameters/personalities isn't reliable, especially considering each combination of hardware, OS, GUI, etc. and individual work practices.

A 1p compilation of an mp engine is a very convenient thing to have.
