Re: Houdini 6.01 released

Now, why would he do that ? If he has cluster version of Houdini, it is purely for his own enjoyment :) Because people - at least a few - would buy it.... :P Dual socket G34 boards and CPUs are dirt cheap these days. Given a supply of old HD/SSDs and power supplies (I got both) a person can piece t...

Robert,

I seem to recall you running Houdini on a giant cluster at several tournaments.
Do you have any plans to publicly release a cluster-capable version?

Thanks

Thanks all for your help.

FYI - Threadripper must be in quad channel to provide full performance!
YEA!!!

Perhaps you could run some chess benchmarks using different memory speeds and timings? Increase the latency, use a higher frequency divider, etc.

Re: RAM for chess, 16 or 32 GB ?

Also keep in mind that you can't run a 16 gig hash table on a 16 gig system without running into horrible paging. The engine, OS, etc. will always chew a gig or two.... Most cost effective would be something like 18/20 gig, or 34/36 gig. (2^X + 2/4GB) Unfortunately, this will require installing two ...

Yup. Otherwise, the Ryzen 5 sure wouldn't be splitting two R7 8 core chips!

Re: AMD Ryzen 1800X rig suggestions

Keep in mind that 32 GB of ram doesn't mean you can run 32G hash tables - the OS and chess program itself need space to live. Adding another 2x2gb or so should do the trick, but this may reduce the maximum ram speed and/or increase latency. I don't see a simple solution. Maybe get 64g and run two in...
